A new version of the Python module which wraps GnuPG has been released.
This is an enhancement and bug-fix release, and all users are encouraged to upgrade.
See the project website  for more information.
* Updated message handling logic to no longer raise exceptions when a message isn't
recognised. Thanks to Daniel Kahn Gillmor for the patch.
* Always use always use --fixed-list-mode, --batch and --with-colons. Thanks to Daniel
Kahn Gillmor for the patch.
* Improved scan_keys() handling on GnuPG >= 2.1. Thanks to Daniel Kahn Gillmor for the
* Improved test behaviour with GnuPG >= 2.1. Failures when deleting test directory trees
are now ignored. Thanks to Daniel Kahn Gillmor for the patch.
* Added close_file keyword argument to verify_file to allow the file closing to be made
optional. Current behaviour is maintained - close_file=False can be passed to skip
closing the file being verified.
* Added the extra_args keyword parameter to allow custom arguments to be passed to the
* Instances of the GPG class now have an additional on_data attribute, which defaults to
None. It can be set to a callable which will be called with a single argument - a binary
chunk of data received from the gpg executable. The callable can do whatever it likes
with the chunks passed to it - e.g. write them to a separate stream. The callable should
not raise any exceptions (unless it wants the current operation to fail).

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.
>>> import gnupg
>>> gpg = gnupg.GPG(gnupghome='/path/to/keyring/directory')
'uids': ['', 'Gary Gross (A test user) <gary.gr... at gamma.com>']},
'uids': ['', 'Danny Davis (A test user) <danny.da... at delta.com>']}]
>>> encrypted = gpg.encrypt("Hello, world!", ['0C5FEFA7A921FC4A'])
'-----BEGIN PGP MESSAGE-----\nVersion: GnuPG v1.4.9 (GNU/Linux)\n
-----END PGP MESSAGE-----\n'
>>> decrypted = gpg.decrypt(str(encrypted), passphrase='secret')
>>> signed = gpg.sign("Goodbye, world!", passphrase='secret')
>>> verified = gpg.verify(str(signed))
>>> print "Verified" if verified else "Not verified"
