TCP (md5 Authentifizierung) TCP-Handshake-Protokolls

[Klaus01]

Hi,
how you have to send the md5 hash to the database
depends on how the database expects the md5hash
as a String or as a ByteCode?

How should the handshake work?
application md5(key) -> database (compares stored md5 hash with received md5hash)

Greetings
Klaus
