Exactly! We haven't yet learned that small and commonly used set -- understandably, since the field is so new. I'd be willing to bet that association between a key and a checking account would be on the list. Beyond that, I don't know. Once an element of that set is identified, it can be assigned a codeword (to make parsing easier). For example, a general certificate might be: - -----BEGIN PGP SIGNED MESSAGE----- Signing-Key-ID: f149b8e7e1f71e60964fff361dae2460 Signed-Key-ID: 76c68cb46a8e3de1509acaf4170feb10 Meaning: I have met this person, introduced to me as James, who signed with that key and I found him to be about 25 years old, roughly 5'11" and with dark hair. Beyond that I don't remember much. - -----BEGIN PGP SIGNATURE----- [...] signature with the signing key - -----END PGP SIGNATURE----- While the specialized one might be: - -----BEGIN PGP SIGNED MESSAGE----- Signing-Key-ID: bc2cb00144f223498fcc074eabb821d0 Signed-Key-ID: e05c601c4ec4af3aeb54a53171ed65da Meaning: checking-account: 116 94265, First Security Bank - -----BEGIN PGP SIGNATURE----- [...] signature with First Security Bank's key - -----END PGP SIGNATURE----- This format has several advantages over ASN.1, of course, but I won't belabor that point here. - Carl +--------------------------------------------------------------------------+ |Carl M.
