MsgAccountSRP6Ex
This client message is sent to the account server to request authentication using SRP6 as an augmented password-authenticated key exchange, replacing the previous MsgAccountSRP6 message. It combines MsgAccountSRP6, MsgConnect, MsgEncryptCode, and MsgPCNum into a single message, and implements a random buffer used as a key derivation function (KDF) in SRP6.
Before handling this message, an account needs to be created using a password verifier and salt rather than a password. The account server is expected look up the account's password verifier in the database to send MsgLoginChallengeS in response to this message.
