Quick SSH History
Secure SHell (SSH) simply is a point to point encrypted connection that acts much like rsh or telnet. It was originally written by Tatu Ylönen (who later started "SSH Communication Security"). This version is referred to as SSH v1 protocol. A later modification to the protocol to improve security is referred to as v1.5. Later Tatu turned over the next version of the protocol to the IETF which is referred to as v2 protocol.
