@BeAware@cdp1337 I couldn’t even export my private key accidentally, even if I wanted. It was generated and lives on an OpenPGP Smartcard and cannot be exported from there (by design!). To decrypt the message @cdp1337 wrote me, I had to insert the card and enter its pin in order to let the smartcard decrypt the message.
Of course, GPG keys can also be stored on the computer within files and nowadays there are USB based solutions like the Yubikey and the Nitrokey, which implemented the same protocol but I still use my old GPG cards. (My primary use-case is that I use them for SSH Public Key authentication to my servers and to sign rpm packages for software, I built)
