I agree with Avi that the KEY field offers a vCard-specific OpenPGP
reference. But the two mechanisms offered have major drawbacks:
KEY lets you include either the full OpenPGP key (very large with modern
RSA keys!) or a download URL (not cryptographically verifiable).
the syntax for KEY has also changed from version to version of vCard :(
I'll try to write up the proposed OPENPGP4FPR: field more explicitly
since it is both short and cryptographically verifiable. You can of
course combine OPENPGP4FPR with the KEY field in a vCard record if you like.
