Thanks. Fortunately Hajime Nakagami has already done a partial protocol 13 implementation (without Srp and wire encryption) as a pull request, so we have a starting point. > In brief handshake in p.13 looks as follows - client sends CONNECT > packet, containing information about login, database client wants to > talk to (required for correct choice of security database on server), > list of known plugins, requirements for line encryption and compression > and some plugin's data (created by the first plugin in that list) for > earlier authentication start.
