Understanding srp6..

[ghroth]

Hello, i would like to get some knowledge about how the account values are generated. To be honest, i'm a delphi beginner and looking in AuthSocket.cpp is just killing my brain cells. What i've foudn so far, are the given values that can be used:

• Account's username is stored in database.
  
• Account's password is stored in database like "sha1(USERNAME:PASSWORD)"
  For example: sha1("USERNAME:PASSWORD") is "5B039D152722E351C8BDEBCF06FD8CD4E5244D78"
  
• N = B79B3E2A87823CAB8F5EBFBF8EB10108535006298B5BADBD5B53E1895E644B89
  
• g = 7
  
• k = 3
  
• Packets stracture: http://www.madx.dk/wowdev/wiki/index.php?title=Packets
  
• SRP Protocol Design: http://srp.stanford.edu/design.html
  

I can also understand that the "v" and the "s" values in database are created and stored by the first account's verification while seasonkey is generating each time the account connects.

What i can't understand is the way of creation of the "seasonkey" and "s" (salt?) values in database.

..the "v" must be "g ^ sha1(s, sha_pass_hash)", right?

Sorry for my bad english and my noobish questions
