How the thing works(WIP!):
Packets have been moved to more meaningful pages.
At the beginning, the WoW Client sends an [[Packets#AuthLogonChallenge_Client|Authentication]] Packet to the Server.
Then the Server checks if the Account is banned etc. and ,if not, sends an [[Packets#AuthLogonChallenge_Server|Packet]] containing information for the [http://srp.stanford.edu/ SRP-6] algorithm.


=Logon=
Login:
The authentication server (and the WoW client) utilizes the [https://en.wikipedia.org/wiki/Secure_Remote_Password_protocol SRP-protocol] for secure authentication.
