Usage Guidelines
This command stores the host key pair in memory (For example, RAM). Use the ip ssh save host-key
command to save the host key pair to flash memory.
Some SSH client programs automatically add the public key to the known hosts file as part of the
configuration process. Otherwise, you must manually create a known hosts file and place the host public key
in it.
The SSH server uses this host key to negotiate a session key and encryption method with the client trying to
connect to it.

Console#ip ssh crypto host-key generate dsa
