![]() ![]() A library exposing the gpgme library to Python, PyMe was released which provided bindings for this. GPGME was originally released as a C library. This library has now completely rewritten the original and has not been vulnerable to some vulnerabilities which have been found in python-gnupg since. In 2013, in response to vulnerabilities in python-gnupg, a fork was made by Isis Lovecruft, this was initially available on PyPi as gnupg but has now been renamed to pretty-bad-protocol to avoid any confusion. The new version uses the subprocess module and so is easiest to use under Pythons >= 2.4. It concentrates on interacting with GnuPG via filehandles, providing access to control GnuPG via versatile and extensible means.Īfter four years from Steve Traugott's work, in July 2009 Vinay Sajip updated the module (now called gnupg.py to avoid confusion) and made it available (under the New BSD License) in tarballs on Google Code. This project has not been updated since 2006 and the project pages are now broken so it should no longer be used in new software. In parallel with the GnuPG interface a separate GnuPGInterface was released in 2002. This was still a pure-python implementation for Python 2.2.1 requiring only gpg executable itself. This was updated in 2005 by SteveTraugott to GPG.py 2005 using pipes) building on Richard Jones' 1.3 update and adding more support for the decryption, signing, key management, bells, whistles, and so on which amk's original design implied. The original Python/GnuPG interface was written by amk. History of libraries that call the gpg program These probably should not be used in new projects. ![]() Not mentioned in this history there are a number of other old libraries which were built to support access to GNU Privacy Guard. This library has had multiple vulnerabilities in the past, however it is under active development so currently known vulnerabilities are believed to have been fixed. Python-gnupg is the most widely used and recommended library. Improvements over python-gnupg include whitelisting of gpg program output designed to protect against vulnerabilities caused by changes in the program output. Python -m pip install pretty-bad-protocol Pretty-bad-protocol is a rewrite of python-gnupg with a more conservative coding approach. This approach is older and more mature than the library but is not recommended and has lead to a number of vulnerabilities both in the python modules, related systems and other programs such as email programs which work in this way. There are multiple libraries which drive the gpg binary as a program and interpret its output. The following commands should install gpgme's python library on various operating systems ![]() Per operating system install instructions The manual is currently missing from the various python documentation repositories but there is an online manual at ( bad HTTPS certificate at time of writing). install and use the version available with your operating system (see table below)īuild gpgme and the associated language bindings and install from source.Although there are python bindings for GPGME included within PyPi which could be installed with pip, this is not recommended by the GPG project and is unlikely to work since the PyPi library version would have to exactly match the version of GNUPG installed on your system. GPGME is the official library for accessing GNU Privacy Guard from programs. The GnuPG initiative recommends using GPGME because it provides a documented API. ![]() There are a couple of principal ways to access GnuPG functions from Python programs: GNU Privacy Guard is a Free Software GNU GPLed implementation of the crypto standards OpenPGP and CMS (used by S/MIME). pgp-mime (using the assuan protocol to gpgme-tool).history of libraries that call the gpg program.per operating system install instructions. ![]()
