Unknown compression algorithm and possible usage of obfuscation, personally I will not work on this.

@ekey
What was the xor key used in the old beta?

Dynamic keys generated by Mersenne Twister algorithm from dwSeed. As dwSeed used hash (fnv1a) from file name.

In old client version packages names hashed like.

Code:

Idk in latest version.

Ok it is use zlib to compression,but data are encrypted by the files name!?

who can help decode the .dat package?

Ekey, posted Sun Dec 07, 2014 2:50 pm (2124)

Algorithm used SHA1 Salsa20 XOR. Keys and IVs not static. As compression used LZMA.

I pass.
