Information
After you regenerate an SSH server key with a customized bit size, disable and re-enable the SSH server to
use the new public keys. To verify the changes, use the show crypto command.
If a remote SSH client uses strict host-key checking, copy a newly generated host key to the list of known
hosts on the client device.
