I think a Diffie-Hellman key exchange would mean even if you surrender your passwords/certificates/etc they still can't decode previously captured network data. Though I think it only works for "real time" communications where the key is destroyed after the communication has completed (e.g. SSL), so it'd protect you from man in the middle attacks when sending email to a trusted server, but it's not useful for storing said data securely.
If my understanding of the above is incorrect I would be interested to know - cryptography is not my strong suit.
