Well, then it is not python-gpg's fault, but the underlying library or components do not differentiate that. > But good to know someone is working on this I'm not. If you feel that this is important, please file a bug.

I gave it a try with 3 tests, one decrypt with cancel'ing the pinentry, one with missing private key and one with a truncated input file. All three gave print str(e): Invocation of gpgme_op_decrypt_verify: GPGME: Decryption failed print e.getcode(): 152 So this doesn't help. But good to know someone is working on this; I'd be happy to help where I can. I am not a C developer, though, but I could test if neccessary.

GPGMEError is a very general error, this is a bit of pyme legacy. You can inspect the error code using .getcode(). For a quick check, try to str() the error.

Questions using GPGME
Hello, I am currently taking first steps using GPGME with the Python interface. I am facing two questions: 1.) I'm looking for a way to get the recipients of encrypted data which I can not/do not want to decrypt. I.e. a message for which I do not have the private key. Enigmail tells me "This message was encrypted for ..." in such cases, and the gpg command line does the same. Is this possible with GPGME? Calling 'decrypt' just raises a GPGMEError in this case and does not return a result. 2.) Is there a way to safely distinguish "User clicked cancel when asked for the passphrase" from other errors? I think an application should abort silently in this case, but I'm getting another GPGMEError without any clue to the reason. I wonder if these are just problems with the python interface or if the functionality is missing from libgpgme. I am currently using gpgme 1.8.0 because that's what is packaged with Debian 9, but if you tell me I need to upgrade, I will ;-) Thanks, Andreas signature.asc Description: OpenPGP digital signature ___ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
