test: add test for "Mixed-Up Mime" message mangling Some MTAs mangle e-mail messages in transit in ways that are repairable. Microsoft Exchange (in particular, the version running today on Office365's mailservers) appears to mangle multipart/encrypted messages in a way that makes them undecryptable by the recipient. I've documented this in section 4.1 "Mixed-up encryption" of draft -00 of https://tools.ietf.org/html/draft-dkg-openpgp-pgpmime-message-mangling Fortunately, it's possible to repair such a message, and notmuch can do that so that a user who receives an encrypted message from a user of office365.com can still decrypt the message. Enigmail already knows about this particular kind of mangling. It describes it as "broken PGP email format probably caused by an old Exchange server", and it tries to repair by directly changing the message held by the user. if this kind of repair goes wrong, the repair process can cause data loss (https://sourceforge.net/p/enigmail/bugs/987/, yikes). The tests introduced here are currently broken. In subsequent patches, i'll introduce a non-destructive form of repair for notmuch so that notmuch users can read mail that has been mangled in this way, and the tests will succeed.

test: replace aging OpenPGP key used in the test suite This replaces the old OpenPGPv4 key that is used in the test suite with a more modern OpenPGPv4 key. All cryptographic artifacts in the test suite are updated accordingly. Having old cryptographic artifacts in the test suite presents a problem once the old algorithms are rejected by contemporary implementations. For reference, this is the old key. sec rsa1024 2011-02-05 [SC] 5AEAB11F5E33DCE875DDB75B6D92612D94E46381 uid [ unknown] Notmuch Test Suite <test_suite@notmuchmail.org> (INSECURE!) ssb rsa1024 2011-02-05 [E] And this is the new key. Note that is has the same shape, but uses Ed25519 and Cv25519 instead of 1024-bit RSA. sec ed25519 2022-09-07 [SC] 9A3AFE6C60065A148FD4B58A7E6ABE924645CC60 uid [ultimate] Notmuch Test Suite (INSECURE!) <test_suite@notmuchmail.org> ssb cv25519 2022-09-07 [E]
