2.13.7 SSH
The SSH, or Secure Shell, protocol is a cryptographic network protocol, allowing secure
remote login by establishing a secure channel between an SSH client and an SSH server. SSH
uses host keys to uniquely identify each SSH server. Host keys are used for server authentication
and identification. A secure unit permits users to create or delete RSA or DSA keys for the
SSH2 protocol.
Note: Only SSH2 is supported due to vulnerabilities in the SSH1 protocol.
