Modified StormLib (MPQ). Here general info

Code: Select all

struct MPKHeader
{
	DWORD	pID;			//MPK\x1A
	DWORD	pVersion;		//String 2000
	DWORD	pArchiveSize;
	DWORD	pUnknown;
	DWORD	pHashTableOffset;
	DWORD	pHashTableSize;
	DWORD	pBlockTableOffset;
	DWORD	pBlockTableSize;
};

Code: Select all

struct MPKHashTable
{
	DWORD	pHashA;
	DWORD	pHashB;
	DWORD	pHashC;
	DWORD	pIndex;			// Index for block table - pBlockIndex = MPKHashTable.pIndex * 20 & 0xFF
};

Code: Select all

struct MPKBlockTable
{
	SHORT	pCFlag;			// 0x1121 - Compressed , 0x1120 - Not compressed
	SHORT	pFlag;			// 0x0001
	DWORD	pOffset;		// File offset
	DWORD	pSize;			// Uncompressed size
	DWORD	pZSize;			// Compressed size
	DWORD	pUnknown;		// 0x86364E6D
};

Here simple code for decrypt block and hash table's + modified hash generator (added alphabet table)

Code: Select all

Currently working on it, but have some problems with saving files.

Done. Archives dont contain file names (only hashes). If you found file name just add in Projects\FileNames.list

WinXP/7 tested. Enjoy.
