Command Usage

• This command stores the host key pair in memory (i.e., 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.

Example

Console#delete public-key admin dsa
Console#

Console#ip ssh crypto host-key generate dsa
