I have the public key I generated using PGP in 2006: PGP PUBLIC KEY BLOCK-----Version: PGP for Personal Privacy 5.0. It is working without problems.
I’m teaching someone how to use Kleopatra, so I exported my public key going through the steps with her over the phone. The PGP PUBLIC KEY BLOCK-----Version: GnuPG v2.0.20 (MingW32) that was generated is much longer than the old one.
I’m confused. Can they both be valid public keys?
