Revision as of 12:51, 9 December 2015
How the thing works(WIP!): At the beginning, the WoW Client sends an Authentication Packet to the Server. Then the Server checks if the Account is banned etc. and ,if not, sends an Packet containing information for the SRP-6 algorithm.
Logon
The authentication server (and the WoW client) utilizes the SRP-protocol for secure authentication.
