A new version of the Python module which wraps GnuPG has been released.
What Changed?
=============
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 tuple.
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 filename
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?
================
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) <[email protected]>']},
{
...
'fingerprint': '37F24DD4B918CC264D4F31D60C5FEFA7A921FC4A',
'keyid': '0C5FEFA7A921FC4A',
'length': '1024',
...
'uids': ['', 'Danny Davis (A test user) <[email protected]>']}]
>>> encrypted = gpg.encrypt("Hello, world!", ['0C5FEFA7A921FC4A'])
>>> str(encrypted)
'-----BEGIN PGP MESSAGE-----\nVersion: GnuPG v1.4.9
(GNU/Linux)\n\nhQIOA/6NHMDTXUwcEAf
...
-----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"
'Verified'
