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# ip ssh crypto host-key generate dsa
Console#
Related Commands

ip ssh save host-key
