Re: [cryptography] [Cryptography] Email encryption for the wider public
very good suggestion! i've been following this thread with interest. relevant to a commercial product i am working on. i thought keeping the key in the address book was the most practical idea. but, you still have to exchange the keys. the biggest problem is the lookup for a key in a key server (keystore). but, automatically sending a separate header sounds, er...automatic, transparent to the user. and lets the system do the work. long, more than 10 digits, unintelligible email addresses won't work. imho. can't be memorized, even if chunked. too many pieces.
