Message Format:
(does not include protocol header)		 
(UINT32)     Client Token
(UINT32)     Server Token
 (UINT8)[20] Password Hash
(STRING)     Username

Remarks

Contains Client's username and hashed password.

Battle.net password hashes are hashed twice using XSHA-1. First, the password is hashed by itself, then the following data is hashed again and sent to Battle.net:

  1. (UINT32) Client Token
  2. (UINT32) Server Token
  3. (UINT8)[20] First password hash

Passwords should be converted to lowercase before hashing, for compatibility with Blizzard games.
