I'm looking for a web front-end or some easy way to get a user who's never been exposed to cryptography / digital signatures etc. to simply copy/paste my GPG signed (not encrypted) email and specify whether that email/text has been correctly signed - meaning contents are untampered and from me - the sender.
Ideally, it would be able to pull my public key off a key server in order to verify or allow a user to upload the key along with the signed text for verification.
Basically - how would I be able to convince an ordinary user that the email sent is indeed from me.
UPDATE: I found something similar here, but apparently it only works for users who've signed up for HushMail.
3thats the main reason why crypto is not (yet) deployed among non-techies :) – akira – 2010-12-12T10:02:03.837
@akira, well not when using PGP maybe. S/MIME signed email is handled fine by sane email clients.
