A new version (0.3.5) of python-gnupg has been released.

30 Aug 2013

      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:

Added improved shell quoting to guard against shell injection attacks.
Added search_keys() and send_keys() methods to interact with keyservers.
A symmetric cipher algorithm can now be specified when encrypting.
UTF-8 encoding is used as a fall back when no other encoding can be determined.
The key length now defaults to 2048 bits.
A default Name-Comment field is no longer provided during key generation.

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) ']},
 {
  ...
  'fingerprint': '37F24DD4B918CC264D4F31D60C5FEFA7A921FC4A',
  'keyid': '0C5FEFA7A921FC4A',
  'length': '1024',
  ...
  'uids': ['', 'Danny Davis (A test user) ']}]
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'
