- Use regular expressions instead of finding particular characters in gnupg
output to decide whether confirmation line was found.
- Use tempfile.mkdtemp to create secure temporary directories.
- Record information about the key considered by GnuPG. When missing in
exception, it means no key was found.
- ContentManager sets default Content-Type even if it was missing in the
original message.
- Make sure that when Content-Type is missing, copying parameters doesn't
raise an error.
- Add a unit-test to check that.
In the daemon, specify policy as SMTPUTF8. That sets the deafult message type
to EmailMessage.
EmailMessage class is richer, including support for Content Managers, giving
it the capability to properly handle textual data and its encodings.
Also: add another contract test.
- Use MIMEPart instead of Message when encrypting in PGP/MIME mode.
- Wrap text/plain messages in MIMEPart, instead of manipulating payloads
manually.
- Add a test for wrapping.
- Clean up PGP/MIME flow by using API instead of explicit/manual generation of
headers.
- Fix E2E test configuration for PGP/MIME case.
- Add first lacre.core unit tests.
- Add another Contract Test.
When GnuPG refuses to encrypt a message (e.g. when key has expired), record
information about the failure and send to logs, then deliver cleartext. This
way we won't bounce email that could be delivered without encryption.
Also: add more E2E tests.
- Cover basic GnuPG functionality with tests (confirm_key, public_keys).
- Add a test public key file.
- Fix resource leak by closing streams opened by Popen.
Extract key-loading code to a dedicated class KeyRing in lacre.keyring module.
KeyCache only keeps a static map of identities, making it safe to use in
asynchronous context (and race condition resistant).
In particular, move:
- test utilities to test/utils;
- unit tests to test/modules.
Also: start implementing the Lacre daemon test (just a stub for now).
