I've put a ticket in to get help with this problem, but I was wondering whether anyone else had a similar issue?

We are currently evaluating the OpenPGP blackbox software. However after some further development with the SDK we have come across some problems with the EncryptSign() method of the PGPWriter class.

We were planning to use a custom .dll which leveraged the calls to encrypt and sign a .zip file before it is send on; but during testing we have found that the program we are using to decrypt (GnuPG) returns with a 'BAD SIGNATURE' error when decrypt & verifying.

Believing that this was merely a bug in our code we stripped everything out and eventually used the sample 'EncryptAndSign' C# project for the test; This still produced the same result.

Any help with this issue would be greatly appreciated.

Sorry for not thinking before posting :).
There was a similar topic about 3 months ago, and part of the discussion was here in the forum (another part was in the helpdesk).

Please check the following:
a) if the issue occurs with the sample PGP keys included to the distribution,
b) if the signature is validated successfully if the file is encrypted/signed using PGPFiles sample.
