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: 
* Subkey information is now collected and returned in a subkey_info  dictionary keyed by the subkey's ID.
* GPG2 version is now correctly detected on OS X.
* Added expect_passphrase keyword argument for use on GnuPG >= 2.1 when  passing passphrase to gpg via pinentry.
* Provided a trust_keys method to allow setting the trust level  for keys. Thanks to William Foster for a suggested implementation.
* Made the exception message when the gpg executable is not found contain the  path of the executable that was tried. Thanks to Kostis Anagnostopoulos for  the suggestion.
* Made the error message less categorical in the case of a failure with an  unspecified reason, adding some information from gpg error codes when  available.

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 \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"
