hi anyone find a way to calculate crc_hash in the AUTH_PROOF msg from the client? that value is needed for the SRP6 calculation in the authorisation section... i think its builded from the values B, M1, A, S and so (see SRP6)... some data from game files are also used... it must be like that: 1. get the auth_challenge_packet from server (provides B, N, g, s values for SRP6-calculation) 2. calculate client-side the values A, M1 3. make a crc from : wow files (*.dll a part of wow.exe) and A,B, M1, s, g? 4. use SHA1 to hash the crc :=> crc_hash key (20 bytes) if that value is not correct the login process fails and the response from the server is a msg (HEX : 01 09) that causes the client to give the msg that the version of the game couldn't readed... thx for ur response exc
