A new version of the Python module which wraps GnuPG has been released.

What Changed?
This is an enhancement and bug-fix release, and all users are encouraged to upgrade.
See the project website [1] for more information.

Brief summary:

* Fixed #38: You can now request information about signatures against
keys. Thanks to SunDwarf for the suggestion and patch, which was used
as a basis for this change.

* Fixed #49: When exporting keys, no attempt is made to decode the output when
armor=False is specified.

* Fixed #53: A ``FAILURE`` message caused by passing an incorrect passphrase
is handled.

* Handled ``EXPORTED`` and ``EXPORT_RES`` messages while exporting keys. Thanks
to Marcel Pörner for the patch.

* Fixed #54: Improved error message shown when gpg is not available.

* Fixed #55: Added support for ``KEY_CONSIDERED`` while verifying.

* Avoided encoding problems with filenames under Windows. Thanks to Kévin
Bernard-Allies for the patch.

* Fixed #57: Used a better mechanism for comparing keys.

What Does It Do?
The gnupg module allows Python programs to make use of the
functionality provided by the Gnu Privacy Guard (abbreviated GPG or
GnuPG). Using this module, Python programs can encrypt and decrypt
data, digitally sign documents and verify digital signatures, manage
(generate, list and delete) encryption keys, using proven Public Key
Infrastructure (PKI) encryption technology based on OpenPGP.

This module is expected to be used with Python versions >= 2.4, as it
makes use of the subprocess module which appeared in that version of
Python. This module is a newer version derived from earlier work by
Andrew Kuchling, Richard Jones and Steve Traugott.

A test suite using unittest is included with the source distribution.

Simple usage:

>>> import gnupg
>>> gpg = gnupg.GPG(gnupghome='/path/to/keyring/directory')
>>> gpg.list_keys()

'fingerprint': 'F819EE7705497D73E3CCEE65197D5DAC68F1AAB2',
'keyid': '197D5DAC68F1AAB2',
'length': '1024',
'type': 'pub',
'uids': ['', 'Gary Gross (A test user) < at>']},
'fingerprint': '37F24DD4B918CC264D4F31D60C5FEFA7A921FC4A',
'keyid': '0C5FEFA7A921FC4A',
'length': '1024',
'uids': ['', 'Danny Davis (A test user) <danny.da... at>']}]
>>> encrypted = gpg.encrypt("Hello, world!", ['0C5FEFA7A921FC4A'])
>>> str(encrypted)

'-----BEGIN PGP MESSAGE-----\nVersion: GnuPG v1.4.9 (GNU/Linux)\n
-----END PGP MESSAGE-----\n'
>>> decrypted = gpg.decrypt(str(encrypted), passphrase='secret')
>>> str(decrypted)

'Hello, world!'
>>> signed = gpg.sign("Goodbye, world!", passphrase='secret')
>>> verified = gpg.verify(str(signed))
>>> print "Verified" if verified else "Not verified"


As always, your feedback is most welcome (especially bug reports [3],
patches and suggestions for improvement, or any other points via the
mailing list/discussion group [4]).
