Small question

Hey everyone.

By the looks of it, it would appear as though the entire "private server" scene for Perfect World is run by binaries, and thus the actual workings of packets between the server / client is probably not very well known, but I figured I would ask anyway.

Does anyone know the game encryptions used by Perfect World, the packet structs, anything like this?

Thanks!

For encryption PW use RC4 (ArcFour algorithm). For decompression packets - MPPC decompression algorithm (read rfc 2118, MPPE/MPPC). Also, for keys - md5 and SHA-256 which choose before auth packets will be sent to server.
