As long as we're talking solely about "signed" and "encrypted" (so no
verification-wise information whatsoever), I'd definitely vote for a
dedicated database field.

It's absolutely immutable metadata, embedded in the message content.

No point in using tags for that, though it's not mutually exclusive:
"notmuch tag +signed -- is:signed" (or whatever, knock yourself out)

If folders -which DO change, although rarely- got one, so should crypto.


...but that's just my (insufficiently) humble opinion.
