How are GPG keys used?

Private keys are the first half of a GPG key which is used to decrypt messages that are encrypted using the public key, as well as signing messages – a technique used to prove that you own the key. Public keys are the second half of a key which is used to encrypt messages for the owner of the private key.

How do I find my GPG key in Linux?

To check if you have existing GPG keys:

1. In a terminal, use this command to list GPG keys you have access to: gpg –list-secret-keys –keyid-format LONG.
2. Check the output to see if you have a GPG key pair.
3. If there are no GPG key pairs, you’ll need to generate a new GPG key.
