+1. INTRODUCTION TO THE MOPAQ FORMAT
+The MoPaQ (or MPQ) format is an archive file format designed by Mike O'Brien (hence the name Mike O'brien PaCK) at Blizzard
+Entertainment. The format has been used in all Blizzard games since (and including) Diablo. It is heavily optimized to be
+a read-only game archive format, and excels at this role. 
+
+The Blizzard MoPaQ-reading functions are contained in the Storm module, which my be either statically or dynamically linked.
+The Blizzard MoPaQ-writing functions are contained in the MPQAPI module, which is always statically linked.
+
+2. THE MOPAQ FORMAT
+All numbers in the MoPaQ format are in little endian. Data types are listed either as int (integer, the number of bits specified),
+byte (8 bits), and char (bytes which contain ASCII characters). All sizes and offsets are in bytes, unless specified otherwise.
+Structure members are listed in the following general form:
+offset from the beginning of the structure: data type(array size) member name : member description
+
+2.1 GENERAL ARCHIVE LAYOUT
+- Archive Header
+- File Data
+- File Data - Special Files
+- Hash Table
+- Block Table
+- Strong Digital signature
+
+This is the usual archive format, and is not absolutely essential. Some archives have been observed placing the hash table
+and file table after the archive header, and before the file data.
+
+2.2 ARCHIVE HEADER
+00h: char(4) Magic : Indicates that the file is a MoPaQ archive. Must be ASCII "MPQ" 1Ah.
+04h: int32 HeaderSize : Size of the archive header. Should be 32.
+08h: int32 ArchiveSize : Size of the whole archive, including the header. Does not include the strong digital signature, if present.
+This size is used, among other things, for determining the region to hash in computing the digital signature.
+0Ch: int16 Unknown : Unknown
+0Eh: int8 SectorSizeShift : Power of two exponent specifying the number of 512-byte disk sectors in each logical sector
+in the archive. The size of each logical sector the archive is 512 * 2^SectorSizeShift. Bugs in the Storm library dictate
+that this should always be 3 (4096 byte sectors).
+10h: int32 HashTableOffset : Offset to the beginning of the hash table, relative to the beginning of the archive.
+14h: int32 BlockTableOffset : Offset to the beginning of the block table, relative to the beginning of the archive.
+18h: int32 HashTableEntries : Number of entries in the hash table. Must be a power of two, and must be less than 2^16.
+1Ch: int32 BlockTableEntries : Number of entries in the block table.
+
+The archive header is the first structure in the archive, at archive offset 0, but the archive does not need to be at offset
+0 of the containing file. The offset of the archive in the file is referred to here as ArchiveOffset. If the archive is not
+at the beginning of the file, it must begin at a disk sector boundary (512 bytes). Early versions of Storm require that the
+archive be at the end of the containing file (ArchiveOffset + ArchiveSize = file size), but this is not required in newer
+versions (due to the strong digital signature not being considered a part of the archive).
+
+2.3 BLOCK TABLE
+The block table contains entries for each region in the archive. Regions may be either files or empty space, which may be
+overwritten by new files (typically this space is from deleted file data). The block table is encrypted, using the hash
+of "(block table)" as the key. Each entry is structured as follows:
+
+00h: int32 BlockOffset : Offset of the beginning of the block, relative to the beginning of the archive. Meaningless if the block size is 0.
+04h: int32 BlockSize : Size of the block in the archive.
+08h: int32 FileSize : Size of the file data stored in the block. Only valid if the block is a file, otherwise meaningless, and should be 0. If the file is compressed, this is the size of the uncompressed file data.
+0Ch: int32 Flags : Bit mask of the flags for the block. The following values are conclusively identified:
+	80000000h: Block is a file, and follows the file data format; otherwise, block is free space, and may be overwritten. If the block is not a file, all other flags should be cleared.
+	01000000h: File is stored as a single unit, rather than split into sectors.
+	00020000h: The file's encryption key is adjusted by the block offset and file size (explained in detail in the File Data section). File must be encrypted.
+	00010000h: File is encrypted.
+	00000200h: File is compressed. Mutually exclusive to file imploded.
+	00000100h: File is imploded. Mutually exclusive to file compressed.
+
+2.4 HASH TABLE
+Instead of storing file names, for quick access MoPaQs use a fixed, power of two-size hash table of files in the archive. A file is uniquely identified by its file path, its language, and its platform. The home entry for a file in the hash table is computed as a hash of the file path. In the event of a collision (the home entry is occupied by another file), progressive overflow is used, and the file is placed in the next available hash table entry. Searches for a desired file in the hash table proceed from the home entry for the file until either the file is found, the entire hash table is searched, or an empty hash table entry (FileBlockIndex of FFFFFFFFh) is encountered. The hash table is encrypted using the hash of "(hash table)" as the key. Each entry is structured as follows:
+
+00h: int32 FilePathHashA : The hash of the file path, using method A.
+04h: int32 FilePathHashB : The hash of the file path, using method B.
+08h: int16 Language : The language of the file. This is a Windows LANGID data type, and uses the same values. 0 indicates the default language (American English), or that the file is language-neutral.
+0Ah: int8 Platform : The platform the file is used for. 0 indicates the default platform. No other values have been observed.
+0Ch: int32 FileBlockIndex : If the hash table entry is valid, this is the index into the block table of the file. Otherwise, one of the following two values:
+	FFFFFFFFh: Hash table entry is empty, and has always been empty. Terminates searches for a given file.
+	FFFFFFFEh: Hash table entry is empty, but was valid at some point (in other words, the file was deleted). Does not terminate searches for a given file.
+
+2.5 FILE DATA
+00h: int32(SectorsInFile + 1) SectorOffsetTable : Offsets to the start of each sector's data, relative to the beginning of the file data. Not present if this information is calculatable (see details below).
+immediately following SectorOffsetTable: SectorData : Data of each sector in the file, packed end to end (see details below).
+
+Normally, file data is split up into sectors, for simple streaming. All sectors, save for the last, will contain as many bytes of file data as specified in the archive header's SectorSizeShift; the last sector may be smaller than this, depending on the size of the file data. This sector size is the size of the raw file data; if the file is compressed, the compressed sector will be smaller or the same size as the uncompressed sector size. Individual sectors in a compressed file may be stored uncompressed; this occurs if and only if the sector could not be compressed by the algorithm used (if the compressed sector size was greater than or equal to the size of the raw data), and is indicated by the sector's compressed size in SectorOffsetTable being equal to the uncompressed size of the sector (which may be calculated from the FileSize).
+
+If the sector is compressed (but not imploded), a bit mask byte of the compression algorithm(s) used to compress the sector is appended to the beginning of the compressed sector data. This additional byte counts towards the total size of the sector; if the size of the sector (including this byte) exceeds or matches the uncompressed size of the sector data, the sector will be stored uncompressed, and this byte omitted. Multiple compression algorithms may be used on the same sector; in this case, successive compression occurs in the order the algorithms are listed below, and decompression occurs in the opposite order. For implimentations of all of these algorithms, see StormLib.
+	40h: IMA ADPCM mono
+	80h: IMA ADPCM stereo
+	01h: Huffman encoded
+	02h: Deflated (see ZLib)
+	08h: Imploded (see PKWare Data Compression Library)
+	10h: BZip2 compressed (see BZip2)
+
+If the file is stored as a single unit (indicated in the file's Flags), there is effectively only a single sector, which
+contains the entire file.
+
+If the file is encrypted, each sector (after compression and appendage of the compression type byte, if applicable)
+is encrypted with the file's key. The base key for a file is determined by a hash of the file name stripped of the
+directory (i.e. the key for a file named "directory\file" would be computed as the hash of "file"). If this key is
+adjusted, as indicated in the file's Flags, the final key is calculated as ((base key + BlockOffset - ArchiveOffset)
+XOR FileSize) (StormLib - an open-source implementation of the MoPaQ reading and writing functions,
+by Ladislav Zezula - incorrectly uses an AND in place of the XOR). Each sector is encrypted using the key + the
+0-based index of the sector in the file. The SectorOffsetTable, if present, is encrypted using the key - 1.
+
+The SectorOffsetTable is omitted when the sizes and offsets of all sectors in the file are calculatable from the FileSize.
+This can happen in several circumstances. If the file is not compressed/imploded, then the size and offset of all sectors
+is known, based on the archive's SectorSizeShift. If the file is stored as a single unit compressed/imploded, then the
+SectorOffsetTable is omitted, as the single file "sector" corresponds to BlockSize and FileSize, as mentioned previously.
+Note that the SectorOffsetTable will always be present if the file is compressed/imploded and the file is not stored as
+a single unit, even if there is only a single sector in the file (the size of the file is less than or equal to the
+archive's sector size).
+
+2.6 LISTFILE
+The listfile is a very simple extension to the MoPaQ format that contains the file paths of (most) files in the archive.
+The languages and platforms of the files are not stored in the listfile. The listfile is contained in the file "(listfile)",
+and is simply a non-Unix-style text file with one file path on each line, lines terminated with the bytes 0Dh 0Ah. The file
+"(listfile)" may not be listed in the listfile.
+
+2.7 EXTENDED ATTRIBUTES
+The extended attributes are optional file attributes for files in the block table. These attributes were added at times after
+the MoPaQ format was already finalized, and it is not necessary for every archive to have all (or any) of the extended attributes.
+If an archive contains a given attribute, there will be an instance of that attribute for every block in the block table, although
+the attribute will be meaningless if the block is not a file. The order of the attributes for blocks correspond to the order of the
+blocks in the block table, and are of the same number. The attributes are stored in parallel arrays in the "(attributes)" file,
+in the archive. The attributes corresponding to this file need not be valid (and logically cannot be). Unlike all the other
+structures in the MoPaQ format, entries in the extended attributes are NOT guaranteed to be aligned. Also note that in some
+archives, malicious zeroing of the attributes has been observed, perhaps with the intent of breaking archive viewers. This
+file is structured as follows:
+
+00h: int32 Version : Specifies the extended attributes format version. For now, must be 100.
+04h: int32 AttributesPresent : Bit mask of the extended attributes present in the archive:
+	00000001h: File CRC32s.
+	00000002h: File timestamps.
+	00000004h: File MD5s.
+08h: int32(BlockTableEntries) CRC32s : CRC32s of the (uncompressed) file data for each block in the archive. Omitted if the
+archive does not have CRC32s. immediately after CRC32s: FILETIME(BlockTableEntries) Timestamps : Timestamps for each block
+in the archive. The format is that of the Windows FILETIME structure. Omitted if the archive does not have timestamps.
+immediately after Timestamps: MD5(BlockTableEntries) MD5s : MD5s of the (uncompressed) file data for each block in the archive.
+Omitted if the archive does not have MD5s.
+
+2.8 WEAK DIGITAL SIGNATURE
+The weak digital signature is a digital signature using Microsoft CryptoAPI. It is an implimentation of the RSASSA-PKCS1-v1_5
+digital signature protocol, using the MD5 hashing algorithm and a 512-bit (weak) RSA key (for more information about this
+protocol, see the RSA Labs PKCS1 specification). The public key and exponent are stored in a resource in Storm. The signature
+is stored uncompressed, unencrypted in the file "(signature)" in the archive. The archive is hashed from the beginning of the
+archive (ArchiveOffset in the containing file) to the end of the archive (the length indicated by ArchiveSize); the signature
+file is added to the archive before signing, and the space occupied by the file is considered to be all binary 0s during
+signing/verification. This file is structured as follows:
+
+00h: int32 Unknown : Must be 0.
+04h: int32 Unknown : must be 0.
+08h: int512 Signature : The digital signature. Like all other numbers in the MoPaQ format, this is stored in little-endian order.
+
+2.9 STRONG DIGITAL SIGNATURE
+The strong digital signature uses a simple proprietary implementation of RSA signing, using the SHA-1 hashing algorithm and
+a 2048-bit (strong) RSA key. The default public key and exponent are stored in Storm, but other keys may be used as well.
+The strong digital signature is stored immediately after the archive, in the containing file; the entire archive (ArchiveSize
+bytes, starting at ArchiveOffset in the containing file) is hashed as a single block. The signature has the following format:
+
+00h: char(4) Magic : Indicates the presence of a digital signature. Must be "NGIS" ("SIGN" backwards).
+04h: int2048 Signature : The digital signature, stored in little-endian format.
+
+When the Signature field is decrypted with the public key and exponent, and the result stored in little-endian order, it is structured as follows:
+
+00h: byte Padding : Must be 0Bh.
+01h: byte(235) Padding : Must be BBh.
+ECh: byte(20) SHA-1 : SHA-1 hash of the archive, in standard SHA-1 format.
+
+3. ALGORITHM SOURCE CODE
+3.1 ENCRYPTION/DECRYPTION
+I believe this was derived at some point from code in StormLib. Assumes the long type to be 32 bits, and the machine to be little endian order.
+
+unsigned long dwCryptTable[0x500];
+
+void InitializeCryptTable()
+{
+    unsigned long seed   = 0x00100001;
+    unsigned long index1 = 0;
+    unsigned long index2 = 0;
+    int   i;
+
+    for (index1 = 0; index1 < 0x100; index1++)
+    {
+        for (index2 = index1, i = 0; i < 5; i++, index2 += 0x100)
+        {
+            unsigned long temp1, temp2;
+
+            seed  = (seed * 125 + 3) % 0x2AAAAB;
+            temp1 = (seed & 0xFFFF) << 0x10;
+
+            seed  = (seed * 125 + 3) % 0x2AAAAB;
+            temp2 = (seed & 0xFFFF);
+
+            dwCryptTable[index2] = (temp1 | temp2);

+
+1. INTRODUCTION TO THE MOPAQ FORMAT
+The MoPaQ (or MPQ) format is an archive file format designed by Mike O'Brien (hence the name Mike O'brien PaCK) at Blizzard Entertainment. The format has been used in all Blizzard games since (and including) Diablo. It is heavily optimized to be a read-only game archive format, and excels at this role. 
+
+The Blizzard MoPaQ-reading functions are contained in the Storm module, which my be either statically or dynamically linked. The Blizzard MoPaQ-writing functions are contained in the MPQAPI module, which is always statically linked.
+
+StormLib - mentioned several times in this specification - is an open-source MoPaQ reading and writing library written by Ladislav Zezula (no affiliation with Blizzard Entertainment). While it's a bit dated, and does not support all of the newer MoPaQ features, it contains source code to the more exotic compression methods used by MoPaQ, such as the PKWare implode algorithm, MoPaQ's huffman compression algorithm, and the IMA ADPCM compression used by MoPaQ.
+
+2. THE MOPAQ FORMAT
+All numbers in the MoPaQ format are in little endian byte order; signed numbers use the two's complement system. Data types are listed either as int (integer, the number of bits specified), byte (8 bits), or char (bytes which contain ASCII characters). All sizes and offsets are in bytes, unless specified otherwise. Structure members are listed in the following general form:
+offset from the beginning of the structure: data type(array size) member name : member description
+
+2.1 GENERAL ARCHIVE LAYOUT
+- Archive Header
+- File Data
+- File Data - Special Files
+- Hash Table
+- Block Table
+- Extended Block Table
+- Strong Digital signature
+
+This is the usual archive format, but it is not mandatory. Some archives have been observed placing the hash table and file table after the archive header, and before the file data.
+
+2.2 ARCHIVE HEADER
+00h: char(4) Magic : Indicates that the file is a MoPaQ archive. Must be ASCII "MPQ" 1Ah.
+04h: int32 HeaderSize : Size of the archive header.
+08h: int32 ArchiveSize : Size of the whole archive, including the header. Does not include the strong digital signature, if present. This size is used, among other things, for determining the region to hash in computing the digital signature. This field is deprecated in the Burning Crusade MoPaQ format, and the size of the archive is calculated as the size from the beginning of the archive to the end of the hash table, block table, or extended block table (whichever is largest).
+0Ch: int16 FormatVersion : MoPaQ format version. MPQAPI will not open archives where this is negative. Known versions:
+	0000h: Original format. HeaderSize should be 20h, and large archives are not supported.
+	0001h: Burning Crusade format. Header size should be 2Ch, and large archives are supported.
+0Eh: int8 SectorSizeShift : Power of two exponent specifying the number of 512-byte disk sectors in each logical sector in the archive. The size of each logical sector in the archive is 512 * 2^SectorSizeShift. Bugs in the Storm library dictate that this should always be 3 (4096 byte sectors).
+10h: int32 HashTableOffset : Offset to the beginning of the hash table, relative to the beginning of the archive.
+14h: int32 BlockTableOffset : Offset to the beginning of the block table, relative to the beginning of the archive.
+18h: int32 HashTableEntries : Number of entries in the hash table. Must be a power of two, and must be less than 2^16 for the original MoPaQ format, or less than 2^20 for the Burning Crusade format.
+1Ch: int32 BlockTableEntries : Number of entries in the block table.
+Fields only present in the Burning Crusade format and later:
+20h: int64 ExtendedBlockTableOffset : Offset to the beginning of the extended block table, relative to the beginning of the archive.
+28h: int16 HashTableOffsetHigh : High 16 bits of the hash table offset for large archives.
+2Ah: int16 BlockTableOffsetHigh : High 16 bits of the block table offset for large archives.
+
+The archive header is the first structure in the archive, at archive offset 0; however, the archive does not need to be at offset 0 of the containing file. The offset of the archive in the file is referred to here as ArchiveOffset. If the archive is not at the beginning of the file, it must begin at a disk sector boundary (512 bytes). Early versions of Storm require that the archive be at the end of the containing file (ArchiveOffset + ArchiveSize = file size), but this is not required in newer versions (due to the strong digital signature not being considered a part of the archive).
+
+2.3 BLOCK TABLE
+The block table contains entries for each region in the archive. Regions may be either files, empty space, which may be overwritten by new files (typically this space is from deleted file data), or unused block table entries. Empty space entries should have BlockOffset and BlockSize nonzero, and FileSize and Flags zero; unused block table entries should have BlockSize, FileSize, and Flags zero. The block table is encrypted, using the hash of "(block table)" as the key. Each entry is structured as follows:
+
+00h: int32 BlockOffset : Offset of the beginning of the block, relative to the beginning of the archive.
+04h: int32 BlockSize : Size of the block in the archive.
+08h: int32 FileSize : Size of the file data stored in the block. Only valid if the block is a file; otherwise meaningless, and should be 0. If the file is compressed, this is the size of the uncompressed file data.
+0Ch: int32 Flags : Bit mask of the flags for the block. The following values are conclusively identified:
+	80000000h: Block is a file, and follows the file data format; otherwise, block is free space or unused. If the block is not a file, all other flags should be cleared, and FileSize should be 0.
+	01000000h: File is stored as a single unit, rather than split into sectors.
+	00020000h: The file's encryption key is adjusted by the block offset and file size (explained in detail in the File Data section). File must be encrypted.
+	00010000h: File is encrypted.
+	00000200h: File is compressed. File cannot be imploded.
+	00000100h: File is imploded. File cannot be compressed.
+
+2.4 EXTENDED BLOCK TABLE
+The extended block table was added to support archives larger than 4 gigabytes (2^32 bytes). The table contains the upper bits of the archive offsets for each block in the block table. It is simply an array of int16s, which become bits 32-47 of the archive offsets for each block, with bits 48-63 being zero. Individual blocks in the archive are still limited to 4 gigabytes in size. This table is only present in Burning Crusade format archives that exceed 4 gigabytes size.
+
+As of the Burning Crusade Friends and Family beta, this table is not encrypted.
+
+2.5 HASH TABLE
+Instead of storing file names, for quick access MoPaQs use a fixed, power of two-size hash table of files in the archive. A file is uniquely identified by its file path, its language, and its platform. The home entry for a file in the hash table is computed as a hash of the file path. In the event of a collision (the home entry is occupied by another file), progressive overflow is used, and the file is placed in the next available hash table entry. Searches for a desired file in the hash table proceed from the home entry for the file until either the file is found, the entire hash table is searched, or an empty hash table entry (FileBlockIndex of FFFFFFFFh) is encountered. The hash table is encrypted using the hash of "(hash table)" as the key. Each entry is structured as follows:
+
+00h: int32 FilePathHashA : The hash of the file path, using method A.
+04h: int32 FilePathHashB : The hash of the file path, using method B.
+08h: int16 Language : The language of the file. This is a Windows LANGID data type, and uses the same values. 0 indicates the default language (American English), or that the file is language-neutral.
+0Ah: int8 Platform : The platform the file is used for. 0 indicates the default platform. No other values have been observed.
+0Ch: int32 FileBlockIndex : If the hash table entry is valid, this is the index into the block table of the file. Otherwise, one of the following two values:
+	FFFFFFFFh: Hash table entry is empty, and has always been empty. Terminates searches for a given file.
+	FFFFFFFEh: Hash table entry is empty, but was valid at some point (in other words, the file was deleted). Does not terminate searches for a given file.
+
+2.6 FILE DATA
+The data for each file is composed of the following structure:
+00h: int32(SectorsInFile + 1) SectorOffsetTable : Offsets to the start of each sector, relative to the beginning of the file data. The last entry contains the file size, making it possible to easily calculate the size of any given sector. This table is not present if this information can be calculated (see details below).
+immediately following SectorOffsetTable: SECTOR Sectors(SectorsInFile) : Data of each sector in the file, packed end to end (see details below).
+
+Normally, file data is split up into sectors, for simple streaming. All sectors, save for the last, will contain as many bytes of file data as specified in the archive header's SectorSizeShift; the last sector may contain less than this, depending on the size of the entire file's data. If the file is compressed or imploded, the sector will be smaller or the same size as the file data it contains. Individual sectors in a compressed or imploded file may be stored uncompressed; this occurs if and only if the file data the sector contains could not be compressed by the algorithm(s) used (if the compressed sector size was greater than or equal to the size of the file data), and is indicated by the sector's size in SectorOffsetTable being equal to the size of the file data in the sector (which may be calculated from the FileSize). 
+
+The format of each sector depends on the kind of sector it is. Uncompressed sectors are simply the the raw file data contained in the sector. Imploded sectors are the raw compressed data following compression with the implode algorithm (these sectors can only be in imploded files). Compressed sectors (only found in compressed - not imploded - files) are compressed with one or more compression algorithms, and have the following structure:
+00h: byte CompressionMask : Mask of the compression types applied to this sector. If multiple compression types are used, they are applied in the order listed below, and decompression is performed in the opposite order. This byte counts towards the total sector size, meaning that the sector will be stored uncompressed if the data cannot be compressed by at least two bytes; as well, this byte is encrypted with the sector data, if applicable. The following compression types are defined (for implementations of these algorithms, see StormLib):
+	40h: IMA ADPCM mono
+	80h: IMA ADPCM stereo
+	01h: Huffman encoded
+	02h: Deflated (see ZLib)
+	08h: Imploded (see PKWare Data Compression Library)
+	10h: BZip2 compressed (see BZip2)
+01h: byte(SectorSize - 1) SectorData : The compressed data for the sector.
+
+If the file is stored as a single unit (indicated in the file's Flags), there is effectively only a single sector, which contains the entire file data.
+
+If the file is encrypted, each sector (after compression/implosion, if applicable) is encrypted with the file's key. The base key for a file is determined by a hash of the file name stripped of the directory (i.e. the key for a file named "directory\file" would be computed as the hash of "file"). If this key is adjusted, as indicated in the file's Flags, the final key is calculated as ((base key + BlockOffset - ArchiveOffset) XOR FileSize) (StormLib incorrectly uses an AND in place of the XOR). Each sector is encrypted using the key + the 0-based index of the sector in the file. The SectorOffsetTable, if present, is encrypted using the key - 1.
+
+The SectorOffsetTable is omitted when the sizes and offsets of all sectors in the file are calculatable from the FileSize. This can happen in several circumstances. If the file is not compressed/imploded, then the size and offset of all sectors is known, based on the archive's SectorSizeShift. If the file is stored as a single unit compressed/imploded, then the SectorOffsetTable is omitted, as the single file "sector" corresponds to BlockSize and FileSize, as mentioned previously. However, the SectorOffsetTable will be present if the file is compressed/imploded and the file is not stored as a single unit, even if there is only a single sector in the file (the size of the file is less than or equal to the archive's sector size).
+
+2.7 LISTFILE
+The listfile is a very simple extension to the MoPaQ format that contains the file paths of (most) files in the archive. The languages and platforms of the files are not stored in the listfile. The listfile is contained in the file "(listfile)" (default language and platform), and is simply a text file with file paths separated by ';', 0Dh, 0Ah, or some combination of these. The file "(listfile)" may not be listed in the listfile.
+
+2.8 EXTENDED ATTRIBUTES
+The extended attributes are optional file attributes for files in the block table. These attributes were added at times after the MoPaQ format was already finalized, and it is not necessary for every archive to have all (or any) of the extended attributes. If an archive contains a given attribute, there will be an instance of that attribute for every block in the block table, although the attribute will be meaningless if the block is not a file. The order of the attributes for blocks correspond to the order of the blocks in the block table, and are of the same number. The attributes are stored in parallel arrays in the "(attributes)" file (default language and platform), in the archive. The attributes corresponding to this file need not be valid (and logically cannot be). Unlike all the other structures in the MoPaQ format, entries in the extended attributes are NOT guaranteed to be aligned. Also note that in some archives, malicious zeroing of the attributes has been observed, perhaps with the intent of breaking archive viewers. This file is structured as follows:
+
+00h: int32 Version : Specifies the extended attributes format version. For now, must be 100.
+04h: int32 AttributesPresent : Bit mask of the extended attributes present in the archive:
+	00000001h: File CRC32s.
+	00000002h: File timestamps.
+	00000004h: File MD5s.
+08h: int32(BlockTableEntries) CRC32s : CRC32s of the (uncompressed) file data for each block in the archive. Omitted if the archive does not have CRC32s.
+immediately after CRC32s: FILETIME(BlockTableEntries) Timestamps : Timestamps for each block in the archive. The format is that of the Windows FILETIME structure. Omitted if the archive does not have timestamps.
+immediately after Timestamps: MD5(BlockTableEntries) MD5s : MD5s of the (uncompressed) file data for each block in the archive. Omitted if the archive does not have MD5s.
+
+2.9 WEAK DIGITAL SIGNATURE
+The weak digital signature is a digital signature using Microsoft CryptoAPI. It is an implimentation
+of the RSASSA-PKCS1-v1_5 digital signature protocol, using the MD5 hashing algorithm and a 512-bit (weak)
+RSA key (for more information about this protocol, see the RSA Labs PKCS1 specification). The public key
+and exponent are stored in a resource in Storm, the private key is stored in a separate file, whose filename
+is passed to MPQAPI (the private key is not stored in MPQAPI). The signature is stored uncompressed,
+unencrypted in the file "(signature)" (default language and platform) in the archive. The archive
+is hashed from the beginning of the archive (ArchiveOffset in the containing file) to the end of
+the archive (the length indicated by ArchiveSize, or calculated in the Burning Crusade MoPaQ format);
+the signature file is added to the archive before signing, and the space occupied by the file is considered
+to be all binary 0s during signing/verification. This file is structured as follows:
+
+00h: int32 Unknown : Must be 0.
+04h: int32 Unknown : Must be 0.
+08h: int512 Signature : The digital signature. Like all other numbers in the MoPaQ format, this is stored
+in little-endian order. The structure of this, when decrypted, follows the RSASSA-PKCS1-v1_5 specification;
+this format is rather icky to work with (I wrote a program to verify this signature using nothing but an MD5
+function and huge integer functions; it wasn't pleasant), and best left to an encryption library such as Cryto++.
+
+2.10 STRONG DIGITAL SIGNATURE
+The strong digital signature uses a simple proprietary implementation of RSA signing, using the SHA-1 hashing algorithm and a 2048-bit (strong) RSA key. The default public key and exponent are stored in Storm, but other keys may be used as well. The strong digital signature is stored immediately after the archive, in the containing file; the entire archive (ArchiveSize bytes, starting at ArchiveOffset in the containing file) is hashed as a single block. The signature has the following format:
+
+00h: char(4) Magic : Indicates the presence of a digital signature. Must be "NGIS" ("SIGN" backwards).
+04h: int2048 Signature : The digital signature, stored in little-endian format.
+
+When the Signature field is decrypted with the public key and exponent, and the resulting large integer is stored in little-endian order, it is structured as follows:
+
+00h: byte Padding : Must be 0Bh.
+01h: byte(235) Padding : Must be BBh.
+ECh: byte(20) SHA-1 : SHA-1 hash of the archive, in standard SHA-1 byte order.
+
+3. ALGORITHM SOURCE CODE
+All of the sample code here assumes little endian machine byte order, that the short type is 16 bits, that the long type is 32 bits, and that the long long type is 64 bits. Adjustments must be made if these assumptions are not correct on a given platform. All code not credited otherwise was written by myself in the writing of this specification.
+
+3.1 ENCRYPTION/DECRYPTION
+Based on code from StormLib.

+
+3.2 HASHING AND FILE KEY COMPUTATION
+These functions may have been derived from StormLib code at some point in the very distant past. It was so long ago that I don't remember for certain.

+#define MPQ_HASH_NAME_A	1
+#define MPQ_HASH_NAME_B	2

+unsigned long HashString(const char *lpszString, unsigned long dwHashType)
+{
+    assert(lpszString);
+    assert(dwHashType <= MPQ_HASH_FILE_KEY);
+

+4. REVISION HISTORY
+1.0
+	- Updated to include most of the changes found in the Burning Crusade Friends and Family beta
+
+0.91.
+	- Updated several structure member descriptions
+	- Listed the full set of characters that can separate list file entries
+	- Noted that (attributes), (listfile), and (signature) use the default language and platform codes
+	- Redid part of the file data specs to clarify the format of sectors
+	- Enhanced descriptions of the different kinds of block table entries
+	- Added ComputeFileKey, FindFileInHashTable, and DeleteFile source

+lookup3.c, by Bob Jenkins, May 2006, Public Domain.
+
+These are functions for producing 32-bit hashes for hash table lookup.
+hashword(), hashlittle(), hashlittle2(), hashbig(), mix(), and final() 
+are externally useful functions.  Routines to test the hash are included 
+if SELF_TEST is defined.  You can use this free for any purpose.  It's in
+the public domain.  It has no warranty.
+
+You probably want to use hashlittle().  hashlittle() and hashbig()
+hash byte arrays.  hashlittle() is is faster than hashbig() on
+little-endian machines.  Intel and AMD are little-endian machines.
+On second thought, you probably want hashlittle2(), which is identical to
+hashlittle() except it returns two 32-bit hashes for the price of one.  
+You could implement hashbig2() if you wanted but I haven't bothered here.
+
+If you want to find a hash of, say, exactly 7 integers, do
+  a = i1;  b = i2;  c = i3;
+  mix(a,b,c);
+  a += i4; b += i5; c += i6;
+  mix(a,b,c);
+  a += i7;
+  final(a,b,c);
+then use c as the hash value.  If you have a variable length array of
+4-byte integers to hash, use hashword().  If you have a byte array (like
+a character string), use hashlittle().  If you have several byte arrays, or
+a mix of things, see the comments above hashlittle().  
+
+Why is this so big?  I read 12 bytes at a time into 3 4-byte integers, 
+then mix those integers.  This is fast (you can do a lot more thorough
+mixing with 12*3 instructions on 3 integers than you can with 3 instructions
+on 1 byte), but shoehorning those bytes into integers efficiently is messy.

+mix -- mix 3 32-bit values reversibly.
+
+This is reversible, so any information in (a,b,c) before mix() is
+still in (a,b,c) after mix().
+
+If four pairs of (a,b,c) inputs are run through mix(), or through
+mix() in reverse, there are at least 32 bits of the output that
+are sometimes the same for one pair and different for another pair.
+This was tested for:
+* pairs that differed by one bit, by two bits, in any combination
+  of top bits of (a,b,c), or in any combination of bottom bits of
+  (a,b,c).
+* "differ" is defined as +, -, ^, or ~^.  For + and -, I transformed
+  the output delta to a Gray code (a^(a>>1)) so a string of 1's (as
+  is commonly produced by subtraction) look like a single 1-bit
+  difference.
+* the base values were pseudorandom, all zero but one bit set, or 
+  all zero plus a counter that starts at zero.
+
+Some k values for my "a-=c; a^=rot(c,k); c+=b;" arrangement that
+satisfy this are
+    4  6  8 16 19  4
+    9 15  3 18 27 15
+   14  9  3  7 17  3
+Well, "9 15 3 18 27 15" didn't quite get 32 bits diffing
+for "differ" defined as + with a one-bit base and a two-bit delta.  I
+used http://burtleburtle.net/bob/hash/avalanche.html to choose 
+the operations, constants, and arrangements of the variables.
+
+This does not achieve avalanche.  There are input bits of (a,b,c)
+that fail to affect some output bits of (a,b,c), especially of a.  The
+most thoroughly mixed value is c, but it doesn't really even achieve
+avalanche in c.
+
+This allows some parallelism.  Read-after-writes are good at doubling
+the number of bits affected, so the goal of mixing pulls in the opposite
+direction as the goal of parallelism.  I did what I could.  Rotates
+seem to cost as much as shifts on every machine I could lay my hands
+on, and rotates are much kinder to the top and bottom bits, so I used
+rotates.

+/* LibTomMath, multiple-precision integer library -- Tom St Denis
+ *
+ * LibTomMath is a library that provides multiple-precision
+ * integer arithmetic as well as number theoretic functionality.
+ *
+ * The library was designed directly after the MPI library by
+ * Michael Fromberger but has been written from scratch with
+ * additional optimizations in place.
+ *
+ * The library is free for all purposes without any express
+ * guarantee it works.

+  Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:
+  x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
+
+  Polynomials over GF(2) are represented in binary, one bit per coefficient,
+  with the lowest powers in the most significant bit.  Then adding polynomials
+  is just exclusive-or, and multiplying a polynomial by x is a right shift by
+  one.  If we call the above polynomial p, and represent a byte as the
+  polynomial q, also with the lowest power in the most significant bit (so the
+  byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
+  where a mod b means the remainder after dividing a by b.
+
+  This calculation is done using the shift-register method of multiplying and
+  taking the remainder.  The register is initialized to zero, and for each
+  incoming bit, x^32 is added mod p to the register if the bit is a one (where
+  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
+  x (which is shifting right by one and adding x^32 mod p if the bit shifted
+  out is a one).  We start with the highest power (least significant bit) of
+  q and repeat for all eight bits of q.
+
+  The first table is simply the CRC of all possible eight bit values.  This is
+  all the information needed to generate CRCs on data a byte at a time for all
+  combinations of CRC register values and incoming bytes.  The remaining tables
+  allow for word-at-a-time CRC calculation for both big-endian and little-
+  endian machines, where a word is four bytes.

+/*
+ *  ALGORITHM
+ *
+ *      The "deflation" process depends on being able to identify portions
+ *      of the input text which are identical to earlier input (within a
+ *      sliding window trailing behind the input currently being processed).
+ *
+ *      The most straightforward technique turns out to be the fastest for
+ *      most input files: try all possible matches and select the longest.
+ *      The key feature of this algorithm is that insertions into the string
+ *      dictionary are very simple and thus fast, and deletions are avoided
+ *      completely. Insertions are performed at each input character, whereas
+ *      string matches are performed only when the previous match ends. So it
+ *      is preferable to spend more time in matches to allow very fast string
+ *      insertions and avoid deletions. The matching algorithm for small
+ *      strings is inspired from that of Rabin & Karp. A brute force approach
+ *      is used to find longer strings when a small match has been found.
+ *      A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
+ *      (by Leonid Broukhis).
+ *         A previous version of this file used a more sophisticated algorithm
+ *      (by Fiala and Greene) which is guaranteed to run in linear amortized
+ *      time, but has a larger average cost, uses more memory and is patented.
+ *      However the F&G algorithm may be faster for some highly redundant
+ *      files if the parameter max_chain_length (described below) is too large.
+ *
+ *  ACKNOWLEDGEMENTS
+ *
+ *      The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
+ *      I found it in 'freeze' written by Leonid Broukhis.
+ *      Thanks to many people for bug reports and testing.

+   Decode literal, length, and distance codes and write out the resulting

+   When large enough input and output buffers are supplied to inflate(), for
+   example, a 16K input buffer and a 64K output buffer, more than 95% of the
+   inflate execution time is spent in this routine.
+
+   Entry assumptions:

+

+      Therefore if strm->avail_in >= 6, then there is enough input to avoid
+      checking for available input while decoding.
+
+    - The maximum bytes that a single length/distance pair can output is 258
+      bytes, which is the maximum length that can be coded.  inflate_fast()

+/* inflate.c -- zlib decompression
+ * Copyright (C) 1995-2005 Mark Adler
+ * For conditions of distribution and use, see copyright notice in zlib.h
+ */
+
+/*
+ * Change history:
+ *
+ * 1.2.beta0    24 Nov 2002
+ * - First version -- complete rewrite of inflate to simplify code, avoid
+ *   creation of window when not needed, minimize use of window when it is
+ *   needed, make inffast.c even faster, implement gzip decoding, and to
+ *   improve code readability and style over the previous zlib inflate code
+ *
+ * 1.2.beta1    25 Nov 2002
+ * - Use pointers for available input and output checking in inffast.c
+ * - Remove input and output counters in inffast.c
+ * - Change inffast.c entry and loop from avail_in >= 7 to >= 6
+ * - Remove unnecessary second byte pull from length extra in inffast.c
+ * - Unroll direct copy to three copies per loop in inffast.c
+ *
+ * 1.2.beta2    4 Dec 2002
+ * - Change external routine names to reduce potential conflicts
+ * - Correct filename to inffixed.h for fixed tables in inflate.c
+ * - Make hbuf[] unsigned char to match parameter type in inflate.c
+ * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset)
+ *   to avoid negation problem on Alphas (64 bit) in inflate.c
+ *
+ * 1.2.beta3    22 Dec 2002
+ * - Add comments on state->bits assertion in inffast.c
+ * - Add comments on op field in inftrees.h
+ * - Fix bug in reuse of allocated window after inflateReset()
+ * - Remove bit fields--back to byte structure for speed
+ * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths
+ * - Change post-increments to pre-increments in inflate_fast(), PPC biased?
+ * - Add compile time option, POSTINC, to use post-increments instead (Intel?)
+ * - Make MATCH copy in inflate() much faster for when inflate_fast() not used
+ * - Use local copies of stream next and avail values, as well as local bit
+ *   buffer and bit count in inflate()--for speed when inflate_fast() not used
+ *
+ * 1.2.beta4    1 Jan 2003
+ * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings
+ * - Move a comment on output buffer sizes from inffast.c to inflate.c
+ * - Add comments in inffast.c to introduce the inflate_fast() routine
+ * - Rearrange window copies in inflate_fast() for speed and simplification
+ * - Unroll last copy for window match in inflate_fast()
+ * - Use local copies of window variables in inflate_fast() for speed
+ * - Pull out common write == 0 case for speed in inflate_fast()
+ * - Make op and len in inflate_fast() unsigned for consistency
+ * - Add FAR to lcode and dcode declarations in inflate_fast()
+ * - Simplified bad distance check in inflate_fast()
+ * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new
+ *   source file infback.c to provide a call-back interface to inflate for
+ *   programs like gzip and unzip -- uses window as output buffer to avoid
+ *   window copying
+ *
+ * 1.2.beta5    1 Jan 2003
+ * - Improved inflateBack() interface to allow the caller to provide initial
+ *   input in strm.
+ * - Fixed stored blocks bug in inflateBack()
+ *
+ * 1.2.beta6    4 Jan 2003
+ * - Added comments in inffast.c on effectiveness of POSTINC
+ * - Typecasting all around to reduce compiler warnings
+ * - Changed loops from while (1) or do {} while (1) to for (;;), again to
+ *   make compilers happy
+ * - Changed type of window in inflateBackInit() to unsigned char *
+ *
+ * 1.2.beta7    27 Jan 2003
+ * - Changed many types to unsigned or unsigned short to avoid warnings
+ * - Added inflateCopy() function
+ *
+ * 1.2.0        9 Mar 2003
+ * - Changed inflateBack() interface to provide separate opaque descriptors
+ *   for the in() and out() functions
+ * - Changed inflateBack() argument and in_func typedef to swap the length
+ *   and buffer address return values for the input function
+ * - Check next_in and next_out for Z_NULL on entry to inflate()
+ *
+ * The history for versions after 1.2.0 are in ChangeLog in zlib distribution.

+   advantage, since only the last 32K of output is copied to the sliding window
+   upon return from inflate(), and since all distances after the first 32K of
+   output will fall in the output data, making match copies simpler and faster.
+   The advantage may be dependent on the size of the processor's data caches.

+   inflate() uses a state machine to process as much input data and generate as
+   much output data as possible before returning.  The state machine is
+   structured roughly as follows:
+
+    for (;;) switch (state) {
+    ...
+    case STATEn:
+        if (not enough input data or output space to make progress)
+            return;
+        ... make progress ...
+        state = STATEm;
+        break;
+    ...
+    }
+
+   so when inflate() is called again, the same case is attempted again, and
+   if the appropriate resources are provided, the machine proceeds to the
+   next state.  The NEEDBITS() macro is usually the way the state evaluates
+   whether it can proceed or should return.  NEEDBITS() does the return if
+   the requested bits are not available.  The typical use of the BITS macros
+   is:
+
+        NEEDBITS(n);
+        ... do something with BITS(n) ...
+        DROPBITS(n);
+
+   where NEEDBITS(n) either returns from inflate() if there isn't enough
+   input left to load n bits into the accumulator, or it continues.  BITS(n)
+   gives the low n bits in the accumulator.  When done, DROPBITS(n) drops
+   the low n bits off the accumulator.  INITBITS() clears the accumulator
+   and sets the number of available bits to zero.  BYTEBITS() discards just
+   enough bits to put the accumulator on a byte boundary.  After BYTEBITS()
+   and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
+
+   NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
+   if there is no input available.  The decoding of variable length codes uses
+   PULLBYTE() directly in order to pull just enough bytes to decode the next
+   code, and no more.
+
+   Some states loop until they get enough input, making sure that enough
+   state information is maintained to continue the loop where it left off
+   if NEEDBITS() returns in the loop.  For example, want, need, and keep
+   would all have to actually be part of the saved state in case NEEDBITS()
+   returns:
+
+    case STATEw:
+        while (want < need) {
+            NEEDBITS(n);
+            keep[want++] = BITS(n);
+            DROPBITS(n);
+        }
+        state = STATEx;
+    case STATEx:
+
+   As shown above, if the next state is also the next case, then the break
+   is omitted.
+
+   A state may also return if there is not enough output space available to
+   complete that state.  Those states are copying stored data, writing a
+   literal byte, and copying a matching string.
+
+   When returning, a "goto inf_leave" is used to update the total counters,
+   update the check value, and determine whether any progress has been made
+   during that inflate() call in order to return the proper return code.
+   Progress is defined as a change in either strm->avail_in or strm->avail_out.
+   When there is a window, goto inf_leave will update the window with the last
+   output written.  If a goto inf_leave occurs in the middle of decompression
+   and there is no window currently, goto inf_leave will create one and copy
+   output to the window for the next call of inflate().
+
+   In this implementation, the flush parameter of inflate() only affects the
+   return code (per zlib.h).  inflate() always writes as much as possible to
+   strm->next_out, given the space available and the provided input--the effect
+   documented in zlib.h of Z_SYNC_FLUSH.  Furthermore, inflate() always defers
+   the allocation of and copying into a sliding window until necessary, which
+   provides the effect documented in zlib.h for Z_FINISH when the entire input
+   stream available.  So the only thing the flush parameter actually does is:
+   when flush is set to Z_FINISH, inflate() cannot return Z_OK.  Instead it
+   will return Z_BUF_ERROR if it has not reached the end of the stream.

+       symbols by length from short to long, and retaining the symbol order
+       for codes with equal lengths.  Then the code starts with all zero bits
+       for the first code of the shortest length, and the codes are integer

+       increases.  For the deflate format, these bits are stored backwards

+       are incremented backwards.

+       creating from that a table of starting indices for each length in the
+       sorted table, and then entering the symbols in order in the sorted
+       table.  The sorted table is work[], with that space being provided by
+       the caller.
+
+       The length counts are used for other purposes as well, i.e. finding
+       the minimum and maximum length codes, determining if there are any
+       codes at all, checking for a valid set of lengths, and looking ahead
+       at length counts to determine sub-table sizes when building the

+     The 'zlib' compression library provides in-memory compression and
+  decompression functions, including integrity checks of the uncompressed
+  data.  This version of the library supports only one compression method
+  (deflation) but other algorithms will be added later and will have the same
+  stream interface.
+
+     Compression can be done in a single step if the buffers are large
+  enough (for example if an input file is mmap'ed), or can be done by
+  repeated calls of the compression function.  In the latter case, the
+  application must provide more input and/or consume the output
+  (providing more output space) before each call.
+
+     The compressed data format used by default by the in-memory functions is
+  the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+  around a deflate stream, which is itself documented in RFC 1951.
+
+     The library also supports reading and writing files in gzip (.gz) format
+  with an interface similar to that of stdio using the functions that start
+  with "gz".  The gzip format is different from the zlib format.  gzip is a
+  gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
+
+     This library can optionally read and write gzip streams in memory as well.
+
+     The zlib format was designed to be compact and fast for use in memory
+  and on communications channels.  The gzip format was designed for single-
+  file compression on file systems, has a larger header than zlib to maintain
+  directory information, and uses a different, slower check method than zlib.
+
+     The library does not install any signal handler. The decoder checks
+  the consistency of the compressed data, so the library should never
+  crash even in case of corrupted input.

+    deflate compresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full. It may introduce some
+  output latency (reading input without producing any output) except when
+  forced to flush.
+
+    The detailed semantics are as follows. deflate performs one or both of the
+  following actions:
+
+  - Compress more input starting at next_in and update next_in and avail_in
+    accordingly. If not all input can be processed (because there is not
+    enough room in the output buffer), next_in and avail_in are updated and
+    processing will resume at this point for the next call of deflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly. This action is forced if the parameter flush is non zero.
+    Forcing flush frequently degrades the compression ratio, so this parameter
+    should be set only when necessary (in interactive applications).
+    Some output may be provided even if flush is not set.
+
+  Before the call of deflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming
+  more output, and updating avail_in or avail_out accordingly; avail_out
+  should never be zero before the call. The application can consume the
+  compressed output when it wants, for example when the output buffer is full
+  (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
+  and with zero avail_out, it must be called again after making room in the
+  output buffer because there might be more output pending.
+
+    Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
+  decide how much data to accumualte before producing output, in order to
+  maximize compression.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+  flushed to the output buffer and the output is aligned on a byte boundary, so
+  that the decompressor can get all input data available so far. (In particular
+  avail_in is zero after the call if enough output space has been provided
+  before the call.)  Flushing may degrade compression for some compression
+  algorithms and so it should be used only when necessary.
+
+    If flush is set to Z_FULL_FLUSH, all output is flushed as with
+  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+  restart from this point if previous compressed data has been damaged or if
+  random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
+  compression.
+
+    If deflate returns with avail_out == 0, this function must be called again
+  with the same value of the flush parameter and more output space (updated
+  avail_out), until the flush is complete (deflate returns with non-zero
+  avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
+  avail_out is greater than six to avoid repeated flush markers due to
+  avail_out == 0 on return.
+
+    If the parameter flush is set to Z_FINISH, pending input is processed,
+  pending output is flushed and deflate returns with Z_STREAM_END if there
+  was enough output space; if deflate returns with Z_OK, this function must be
+  called again with Z_FINISH and more output space (updated avail_out) but no
+  more input data, until it returns with Z_STREAM_END or an error. After
+  deflate has returned Z_STREAM_END, the only possible operations on the
+  stream are deflateReset or deflateEnd.
+
+    Z_FINISH can be used immediately after deflateInit if all the compression
+  is to be done in a single step. In this case, avail_out must be at least
+  the value returned by deflateBound (see below). If deflate does not return
+  Z_STREAM_END, then it must be called again as described above.
+
+    deflate() sets strm->adler to the adler32 checksum of all input read
+  so far (that is, total_in bytes).
+
+    deflate() may update strm->data_type if it can make a good guess about
+  the input data type (Z_BINARY or Z_TEXT). In doubt, the data is considered
+  binary. This field is only for information purposes and does not affect
+  the compression algorithm in any manner.
+
+    deflate() returns Z_OK if some progress has been made (more input
+  processed or more output produced), Z_STREAM_END if all input has been
+  consumed and all output has been produced (only when flush is set to
+  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
+  if next_in or next_out was NULL), Z_BUF_ERROR if no progress is possible

+    accordingly.  inflate() provides as much output as possible, until there
+    is no more input data or no more space in the output buffer (see below
+    about the flush parameter).
+
+  Before the call of inflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming
+  more output, and updating the next_* and avail_* values accordingly.
+  The application can consume the uncompressed output when it wants, for
+  example when the output buffer is full (avail_out == 0), or after each
+  call of inflate(). If inflate returns Z_OK and with zero avail_out, it
+  must be called again after making room in the output buffer because there
+  might be more output pending.
+
+    The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH,
+  Z_FINISH, or Z_BLOCK. Z_SYNC_FLUSH requests that inflate() flush as much
+  output as possible to the output buffer. Z_BLOCK requests that inflate() stop
+  if and when it gets to the next deflate block boundary. When decoding the
+  zlib or gzip format, this will cause inflate() to return immediately after
+  the header and before the first block. When doing a raw inflate, inflate()
+  will go ahead and process the first block, and will return when it gets to
+  the end of that block, or when it runs out of data.
+
+    The Z_BLOCK option assists in appending to or combining deflate streams.
+  Also to assist in this, on return inflate() will set strm->data_type to the
+  number of unused bits in the last byte taken from strm->next_in, plus 64
+  if inflate() is currently decoding the last block in the deflate stream,
+  plus 128 if inflate() returned immediately after decoding an end-of-block
+  code or decoding the complete header up to just before the first byte of the
+  deflate stream. The end-of-block will not be indicated until all of the
+  uncompressed data from that block has been written to strm->next_out.  The
+  number of unused bits may in general be greater than seven, except when
+  bit 7 of data_type is set, in which case the number of unused bits will be
+  less than eight.
+
+    inflate() should normally be called until it returns Z_STREAM_END or an
+  error. However if all decompression is to be performed in a single step
+  (a single call of inflate), the parameter flush should be set to
+  Z_FINISH. In this case all pending input is processed and all pending
+  output is flushed; avail_out must be large enough to hold all the
+  uncompressed data. (The size of the uncompressed data may have been saved
+  by the compressor for this purpose.) The next operation on this stream must
+  be inflateEnd to deallocate the decompression state. The use of Z_FINISH
+  is never required, but can be used to inform inflate that a faster approach
+  may be used for the single inflate() call.
+
+     In this implementation, inflate() always flushes as much output as
+  possible to the output buffer, and always uses the faster approach on the
+  first call. So the only effect of the flush parameter in this implementation
+  is on the return value of inflate(), as noted below, or when it returns early
+  because Z_BLOCK is used.
+
+     If a preset dictionary is needed after this call (see inflateSetDictionary
+  below), inflate sets strm->adler to the adler32 checksum of the dictionary
+  chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+  strm->adler to the adler32 checksum of all output produced so far (that is,
+  total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+  below. At the end of the stream, inflate() checks that its computed adler32
+  checksum is equal to that saved by the compressor and returns Z_STREAM_END
+  only if the checksum is correct.
+
+    inflate() will decompress and check either zlib-wrapped or gzip-wrapped
+  deflate data.  The header type is detected automatically.  Any information
+  contained in the gzip header is not retained, so applications that need that
+  information should instead use raw inflate, see inflateInit2() below, or
+  inflateBack() and perform their own processing of the gzip header and
+  trailer.
+
+    inflate() returns Z_OK if some progress has been made (more input processed
+  or more output produced), Z_STREAM_END if the end of the compressed data has
+  been reached and all uncompressed output has been produced, Z_NEED_DICT if a
+  preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
+  corrupted (input stream not conforming to the zlib format or incorrect check
+  value), Z_STREAM_ERROR if the stream structure was inconsistent (for example
+  if next_in or next_out was NULL), Z_MEM_ERROR if there was not enough memory,

+
+     This is another version of deflateInit with more compression options. The
+   fields next_in, zalloc, zfree and opaque must be initialized before by
+   the caller.
+
+     The method parameter is the compression method. It must be Z_DEFLATED in
+   this version of the library.
+
+     The windowBits parameter is the base two logarithm of the window size
+   (the size of the history buffer). It should be in the range 8..15 for this
+   version of the library. Larger values of this parameter result in better
+   compression at the expense of memory usage. The default value is 15 if
+   deflateInit is used instead.
+
+     windowBits can also be -8..-15 for raw deflate. In this case, -windowBits
+   determines the window size. deflate() will then generate raw deflate data
+   with no zlib header or trailer, and will not compute an adler32 check value.
+
+     windowBits can also be greater than 15 for optional gzip encoding. Add
+   16 to windowBits to write a simple gzip header and trailer around the
+   compressed data instead of a zlib wrapper. The gzip header will have no
+   file name, no extra data, no comment, no modification time (set to zero),
+   no header crc, and the operating system will be set to 255 (unknown).  If a
+   gzip stream is being written, strm->adler is a crc32 instead of an adler32.
+
+     The memLevel parameter specifies how much memory should be allocated
+   for the internal compression state. memLevel=1 uses minimum memory but
+   is slow and reduces compression ratio; memLevel=9 uses maximum memory
+   for optimal speed. The default value is 8. See zconf.h for total memory
+   usage as a function of windowBits and memLevel.
+
+     The strategy parameter is used to tune the compression algorithm. Use the
+   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+   filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
+   string match), or Z_RLE to limit match distances to one (run-length
+   encoding). Filtered data consists mostly of small values with a somewhat
+   random distribution. In this case, the compression algorithm is tuned to
+   compress them better. The effect of Z_FILTERED is to force more Huffman
+   coding and less string matching; it is somewhat intermediate between
+   Z_DEFAULT and Z_HUFFMAN_ONLY. Z_RLE is designed to be almost as fast as
+   Z_HUFFMAN_ONLY, but give better compression for PNG image data. The strategy
+   parameter only affects the compression ratio but not the correctness of the
+   compressed output even if it is not set appropriately.  Z_FIXED prevents the
+   use of dynamic Huffman codes, allowing for a simpler decoder for special
+   applications.
+
+      deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough

+
+     The dictionary should consist of strings (byte sequences) that are likely

+
+     The windowBits parameter is the base two logarithm of the maximum window
+   size (the size of the history buffer).  It should be in the range 8..15 for
+   this version of the library. The default value is 15 if inflateInit is used
+   instead. windowBits must be greater than or equal to the windowBits value
+   provided to deflateInit2() while compressing, or it must be equal to 15 if
+   deflateInit2() was not used. If a compressed stream with a larger window
+   size is given as input, inflate() will return with the error code
+   Z_DATA_ERROR instead of trying to allocate a larger window.
+
+     windowBits can also be -8..-15 for raw inflate. In this case, -windowBits
+   determines the window size. inflate() will then process raw deflate data,
+   not looking for a zlib or gzip header, not generating a check value, and not
+   looking for any check values for comparison at the end of the stream. This
+   is for use with other formats that use the deflate compressed data format
+   such as zip.  Those formats provide their own check values. If a custom
+   format is developed using the raw deflate format for compressed data, it is
+   recommended that a check value such as an adler32 or a crc32 be applied to
+   the uncompressed data as is done in the zlib, gzip, and zip formats.  For
+   most applications, the zlib format should be used as is. Note that comments
+   above on the use in deflateInit2() applies to the magnitude of windowBits.
+

+     inflateBack() does a raw inflate with a single call using a call-back
+   interface for input and output.  This is more efficient than inflate() for
+   file i/o applications in that it avoids copying between the output and the
+   sliding window by simply making the window itself the output buffer.  This
+   function trusts the application to not change the output buffer passed by
+   the output function, at least until inflateBack() returns.
+
+     inflateBackInit() must be called first to allocate the internal state
+   and to initialize the state with the user-provided window buffer.
+   inflateBack() may then be used multiple times to inflate a complete, raw
+   deflate stream with each call.  inflateBackEnd() is then called to free
+   the allocated state.
+
+     A raw deflate stream is one with no zlib or gzip header or trailer.
+   This routine would normally be used in a utility that reads zip or gzip
+   files and writes out uncompressed files.  The utility would decode the
+   header and process the trailer on its own, hence this routine expects
+   only the raw deflate stream to decompress.  This is different from the
+   normal behavior of inflate(), which expects either a zlib or gzip header and
+   trailer around the deflate stream.
+
+     inflateBack() uses two subroutines supplied by the caller that are then
+   called by inflateBack() for input and output.  inflateBack() calls those
+   routines until it reads a complete deflate stream and writes out all of the
+   uncompressed data, or until it encounters an error.  The function's
+   parameters and return types are defined above in the in_func and out_func
+   typedefs.  inflateBack() will call in(in_desc, &buf) which should return the
+   number of bytes of provided input, and a pointer to that input in buf.  If
+   there is no input available, in() must return zero--buf is ignored in that
+   case--and inflateBack() will return a buffer error.  inflateBack() will call
+   out(out_desc, buf, len) to write the uncompressed data buf[0..len-1].  out()
+   should return zero on success, or non-zero on failure.  If out() returns
+   non-zero, inflateBack() will return with an error.  Neither in() nor out()
+   are permitted to change the contents of the window provided to
+   inflateBackInit(), which is also the buffer that out() uses to write from.
+   The length written by out() will be at most the window size.  Any non-zero
+   amount of input may be provided by in().
+
+     For convenience, inflateBack() can be provided input on the first call by
+   setting strm->next_in and strm->avail_in.  If that input is exhausted, then
+   in() will be called.  Therefore strm->next_in must be initialized before
+   calling inflateBack().  If strm->next_in is Z_NULL, then in() will be called
+   immediately for input.  If strm->next_in is not Z_NULL, then strm->avail_in
+   must also be initialized, and then if strm->avail_in is not zero, input will
+   initially be taken from strm->next_in[0 .. strm->avail_in - 1].
+
+     The in_desc and out_desc parameters of inflateBack() is passed as the
+   first parameter of in() and out() respectively when they are called.  These
+   descriptors can be optionally used to pass any information that the caller-
+   supplied in() and out() functions need to do their job.
+
+     On return, inflateBack() will set strm->next_in and strm->avail_in to
+   pass back any unused input that was provided by the last in() call.  The
+   return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
+   if in() or out() returned an error, Z_DATA_ERROR if there was a format
+   error in the deflate stream (in which case strm->msg is set to indicate the
+   nature of the error), or Z_STREAM_ERROR if the stream was not properly
+   initialized.  In the case of Z_BUF_ERROR, an input or output error can be
+   distinguished using strm->next_in which will be Z_NULL only if in() returned
+   an error.  If strm->next is not Z_NULL, then the Z_BUF_ERROR was due to
+   out() returning non-zero.  (in() will always be called before out(), so
