I suspect you mean "What is the commonly used means of authentication?" This is not a simple subject, but I will attempt to answer only the question that I think you are asking. To associate an electronic object (email message, web page, other electronic document) with a person, that person should sign the object using PGP/GPG. A public key is just a means of checking the signature. A fingerprint is just a way to identify a public key.

You do not need to include your public key in email messages, just include your keyid. The keyid can be used to retrieve your key from key servers. Tony -- Anthony E.
