python3-gpg 1.8.0-3ubuntu5 (i386 binary) in ubuntu artful

 The "gpg" Python module is, for the most part, a direct interface to
 the C GPGME library. However, it is re-packaged in a more Pythonic
 way -- object-oriented with classes and modules. Take a look at the
 classes defined here -- they correspond directly to certain object
 types in GPGME for C.
 .
 Features:
  * Feature-rich, full implementation of the GPGME library. Supports
    all GPGME features except interactive editing (coming soon).
    Callback functions may be written in pure Python.
  * Ability to sign, encrypt, decrypt, and verify data.
  * Ability to list keys, export and import keys, and manage the keyring.
  * Fully object-oriented with convenient classes and modules.
 .
 This is the official upstream Python 3 binding for GPGME.
