Off the top of my head, you could have an encrypted index = +too, which you can only search while able to decrypt. Certainly another lev= +el of complexity.

As far I understand an attacker could reconstruct the message from th= +e
+index, so one question is whether the extra complexity in notmuch is
+worth the minimal extra security over decrypting on delivery and storing +plaintext on the (presumably encrypted) disk. Of course decrypting on
+delivery may be inconvenient (or impossible). I have CCed the two people +who have implemented most of the crypto related stuff in notmuch so they +can comment.
