@skyblond gpg keys FTW :)
@freemo I use xshell to help me remember the password. It's a really complicated one so I can't remember it.
Anyway, I just copied my pub key to the server. Now I can log in using my windows's built-in ssh.
Need some quick port forwarding.
@Hyolobrika You can setup GPG on YubiKeys, so you can sign and encrypt anything using GPG, but that need specific support from application.
@skyblond I usually recommend you keep the original key and encrypt it and secure it away. At the very least you shouldnt be using your master key anyway and should use subkeys.
