Support editing archives, keeping encrypted notes #65

Closed covert-encryption closed 2 years ago

covert-encryption commented 2 years ago

Implements covert edit CLI command that extracts an existing archive, allows editing its text and then re-encrypts the data. Any attached files of the archive are kept without extracting them or the message to disk. The original file is overwritten.

This function is intended to allow adding and removing attachments, as well as using public keys, but for now it is limited to message editing and passphrases. Also, all data must fit in RAM, as no streaming is yet implemented for this mode.

Fixes #57

This needs still some additional work on decoding from pipe (an unrelated bug discovered while testing the new feature), but should be essentially usable now. Armor decoding got an optimisation that makes it noticeably faster for large data.

As additional benefits on end-to-end testing, we can now use stdio pipes and hashing passwords is much faster.

Will need to address that FIXME added in another PR prior to 0.6 release.
