He does have to do more: He has to intercept the messages or deceive you about the email address to use. Both is possible, both are non-triviasl tasks so that you also have to ask: If he can to that why assume that he doesn't just hack your system? > That MITM > is following and logging your interesting conversation without either > of you noticing... So would he with unencrypted messages. Certificate validation does not appear from nowhere. Either you have it or you don't. And in reality you usually have to send the message anyway. IMHO we especially need education for the masses that they become aware that different messages require different security levels (in all areas: key security, authentication security and system security). OpenPGP is not a model technology in that regard, too. As you can read German, at least slowly... ;-) http://www.crypto-fuer-alle.de/wishlist/securitylevel/ Hauke -- Crypto für alle: http://www.openpgp-schulungen.de/fuer/unterstuetzer/ http://userbase.kde.org/Concepts/OpenPGP_Help_Spread OpenPGP: 7D82 FB9F D25A 2CE4 5241 6C37 BF4B 8EEF 1A57 1DF5
