gpg –fingerprint \A key’s fingerprint is verified with the key’s owner. This may be done in person or over the phone or through any other means as long as you can guarantee that you are communicating with the key’s true owner. If the fingerprint you get is the same as the fingerprint the key’s owner gets, then you can be sure that you have a correct copy of the key.
