The difference between SSH1 and SSH2 is they are two entirely different protocols. SSH1 and SSH2 encrypt at different parts of the packets, and SSH1 uses server and host keys to authenticate systems where SSH2 only uses host keys. SSH2 is a complete rewrite of the protocol, and it does not use the same networking implementation that SSH1 does. Also, SSH2 is more secure. Because of the different protocol implementation, they are not compatible.
