if sc2 has the same auth method as wow .. then here goes the wow srp6 auth

if you need wow encryption protocol, you can find it in open source wow servers, ascent is a great source if you need that info.

as i remember wow uses srp6 as encryption protocol

as for the server programming, use python with twisted python and you'll ready

maybe this will help, it is String folder out of battlenet.mpq, it contains some xml files with uid for different client/server states.
