A new version of the Python module which wraps GnuPG has been released.

What Changed?
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
This is a minor enhancement and bug-fix release. See the project website ( =
http://code.google.com/p/python-gnupg/ ) for more information. Summary:

An encoding bug which caused an exception when getting the GPG version has =
been fixed.
Recipients can be passed in a set or frozenset as well as in a list or tupl=
e.
The keyring argument now accepts a list of public keyring filenames as well=
 as a single filename.
A secret_keyring argument has been added which accepts either a single file=
name or a list of filenames for secret keyrings.

The current version passes all tests on Windows (CPython 2.4, 2.5, 2.6, 2.7=
, 3.1 and Jython 2.5.1), Mac OS X (Python 2.5) and Ubuntu (CPython 2.4, 2.5=
, 2.6, 2.7, 3.0, 3.1, 3.2). On Windows, GnuPG 1.4.11 has been used for the =
tests.

What Does It Do?
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
The gnupg module allows Python programs to make use of the functionality pr=
ovided by the Gnu Privacy Guard (abbreviated GPG or GnuPG). Using this modu=
le, Python programs can encrypt and decrypt data, digitally sign documents =
and verify digital signatures, manage (generate, list and delete) encryptio=
n keys, using proven Public Key Infrastructure (PKI) encryption technology =
based on OpenPGP.

This module is expected to be used with Python versions >=3D 2.4, as it mak=
es use of the subprocess module which appeared in that version of Python. T=
his 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 =3D gnupg.GPG(gnupghome=3D'/path/to/keyring/directory')
>>> gpg.list_keys()
[{
  ...
  'fingerprint': 'F819EE7705497D73E3CCEE65197D5DAC68F1AAB2',
  'keyid': '197D5DAC68F1AAB2',
  'length': '1024',
  'type': 'pub',
  'uids': ['', 'Gary Gross (A test user) <gary.gross@gamma.com>']},
 {
  ...
  'fingerprint': '37F24DD4B918CC264D4F31D60C5FEFA7A921FC4A',
  'keyid': '0C5FEFA7A921FC4A',
  'length': '1024',
  ...
  'uids': ['', 'Danny Davis (A test user) <danny.davis@delta.com>']}]
>>> encrypted =3D gpg.encrypt("Hello, world!", ['0C5FEFA7A921FC4A'])
>>> str(encrypted)
'-----BEGIN PGP MESSAGE-----\nVersion: GnuPG v1.4.9 (GNU/Linux)\n\nhQIOA/6N=
HMDTXUwcEAf
...
-----END PGP MESSAGE-----\n'
>>> decrypted =3D gpg.decrypt(str(encrypted), passphrase=3D'secret')
>>> str(decrypted)
'Hello, world!'
>>> signed =3D gpg.sign("Goodbye, world!", passphrase=3D'secret')
>>> verified =3D gpg.verify(str(signed))
>>> print "Verified" if verified else "Not verified"
'Verified'
