I downloaded my private key block from keybase.io (into file keybase.ppk). It starts with:
-----BEGIN PGP PRIVATE KEY BLOCK----- Version: Keybase OpenPGP v2.0.49
I would now like to create a ssh key pair so I can put a public key on a remote server and use the private key to log into it. How do I do it on Linux?
I tried various methods I found on the net and all I learned is that my understanding of applications and standards in contemporary cryptography is very limited :-/
