I've created an RSA keypair for ssh access to a remote server. This all works. When creating the keypair, I didn't enter a password. Now I would like to encrypt the key, secure it with a password.
Is that possible, and if so how can I do that?
How can I encrypt an existing ssh key with a password?
Use this command: ssh-keygen -o -p -f keyfile
Changing the private key's passphrase without changing the key
-p.

-o for new format only works since 6.5 released 2014-01 and is no longer needed (now default) since 7.8 released 2018-08 (in both cases distros often don't take new version immediately).
