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

[Ekey]

First closed beta and second using simple xor. Compression lz series

[heng32032]

i cant find the name of res.

[aluigi]

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

[Ekey]

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

the package name has hashed?It looks like a very hard job

[Ekey]

In old client version packages names hashed like.

Idk in latest version.

[heng32032]

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

[heng32032]

who can help decode the .dat package?

[Ekey]

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

I pass.
