Stacktrace of decryption attempt, with repro. #258

Open sharon-indegy opened 5 years ago

sharon-indegy commented 5 years ago

Hi first let me thank you for this brilliant library.

Repro: import gnupg

gpg = gnupg.GPG(homedir="my .gnupg") decrypt = gpg.decrypt("valid msg omitted, works with 'gpg -d' ")

print decrypt.ok print decrypt.data

I get: Exception in thread Thread-2: Traceback (most recent call last): File "/usr/lib/python2.7/threading.py", line 801, in __bootstrap_inner self.run() File "/usr/lib/python2.7/threading.py", line 754, in run self.target(*self.args, **self.__kwargs) File "/home/sharon/.local/lib/python2.7/site-packages/gnupg/_meta.py", line 650, in _read_response result._handle_status(keyword, value) File "/home/sharon/.local/lib/python2.7/site-packages/gnupg/_parsers.py", line 1757, in _handle_status super(Crypt, self)._handle_status(key, value) File "/home/sharon/.local/lib/python2.7/site-packages/gnupg/_parsers.py", line 1656, in _handle_status raise ValueError("Unknown status message: %r" % key) ValueError: Unknown status message: u'DECRYPTION_KEY'

I think it's a small matter of adding DECRYPTION_KEY to the 'pass' section of the relevant handler. But will take me some time to verify so letting you know right away.

Also, possible that I have an old version compared to this repo, used pip install on debian testing.

Please let me know if more info or testing by me is needed. Great work!

Just saw in your blog how much pain these GnuPG flags cause, I'm sorry to have raised yet another one of those.

First, I'd like to echo, "Hi first let me thank you for this brilliant library."

Second, the bug is a little noisy, but nothing is actually broken.

On WSL2/Debian, latest pip download available as of today ... Requirement already satisfied: gnupg in ./venv/lib/python3.11/site-packages (from -r requirements.txt (line 1)) (2.3.1)

Reading ... which I think relates ... https://gnupg.readthedocs.io/en/latest/ "New in version 0.4.2: The keyid and username of the signing key are stored in the key_id and username attributes of the result, if this information is provided by gpg (which should happen if you specify extra_args=['--verbose'])."

And ... https://github.com/gpg/gnupg/blob/master/doc/DETAILS "DECRYPTION_KEY This line is emitted when a public key decryption succeeded in providing a session key. is the hexified fingerprint of the actual key used for decryption. is the fingerprint of the primary key. is the letter with the ownertrust; this is in general a ‘u’ which stands for ultimately trusted."

I'm currently working around with ...

$ diff _parsers.py.orig _parsers.py 1654a1655,1656

    elif key == 'DECRYPTION_KEY':
        pass
