Copy your private GPG key to a new machine

It’s really simple to copy your private GPG keys to another machine of yours. Let’s do public key first: $ gpg --export --armor KEY | ssh me@my-other-machine 'gpg --import' gpg: keyring `/home/me/.gnupg/secring.gpg' created gpg: keyring `/home/me/.gnupg/pubring.gpg' created gpg: /home/me/.gnupg/trustdb.gpg: trustdb created gpg: key 4937B925: public key "KEY" imported gpg: Total number processed: 1 gpg: imported: 1 (RSA: 1) It worked! Now the private: $ gpg --export-secret-key --armor KEY | ssh me@my-other-machine 'gpg --import --allow-secret-key-import' gpg: key 4937B925: secret key imported gpg: key 4937B925: "KEY" not changed gpg: Total number processed: 1 gpg: unchanged: 1 gpg: secret keys read: 1 gpg: secret keys imported: 1 (--armor is optional, it’s just for sake of checking the output first before piping it to ssh)
