We have a set of public and private keys and certificates on the server. GPG will generate your keys. Now that we have the private key from Keybase we are ready to import it. Protecting a private key with a passphrase needs to be done carefully, as is usually the case in crypto matters. $ gpg --export-secret-keys -a keyid > my_private_key.asc $ gpg --export -a keyid > my_public_key.asc Where keyid is your PGP Key ID, such as A1E732BB. it doesn't matter whether you're using gpg4win or gnupg in order to execute the decryption.
