ANN: A new version (0.3.1) of the Python module which wraps GnuPG has been released.
by Vinay Sajip 01 Sep '12

01 Sep '12

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: Better support for status messages from GnuPG. Support for additional arguments to be passed to GnuPG. Bugs in tests which used Latin-1 encoded data have been fixed by specifying that encoding. On verification (including after decryption), the signer trust level is returned in integer and text formats. The current version passes all tests on Windows (CPython 2.4, 2.5, 2.6, 2.7, 3.1 and Jython 2.5.1), Mac OS X (Python 2.5) and Ubuntu (CPython 2.4, 2.5, 2.6, 2.7, 3.0, 3.1, 3.2). On Windows, GnuPG 1.4.11 has been used for the tests. 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) <gary.gross(a)gamma.com>']}, { ... 'fingerprint': '37F24DD4B918CC264D4F31D60C5FEFA7A921FC4A', 'keyid': '0C5FEFA7A921FC4A', 'length': '1024', ... 'uids': ['', 'Danny Davis (A test user) <danny.davis(a)delta.com>']}] >>> 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' For more information, visit http://code.google.com/p/python-gnupg/ - as always, your feedback is most welcome (especially bug reports, patches and suggestions for improvement). Enjoy! Cheers Vinay Sajip Red Dove Consultants Ltd.

Twisted 12.2.0 released
by Ashwini Oruganti 01 Sep '12

01 Sep '12

On behalf of Twisted Matrix Laboratories, I am honored to announce the release of Twisted 12.2. Highlights for this release include: * To be able to work on Python3 support, Python 2.5 is no longer supported. * twisted.mail.imap4 now serves BODYSTRUCTURE responses which provide more information and conform to the IMAP4 RFC more closely. * twisted.conch now supports commercial SSH implementations which don't comply with the IETF standard. * twisted.internet.endpoints now provides several new endpoints, including a TCP client endpoint that resolves hostnames to IPv6 host addresses. * IReactorSocket.adoptStreamConnection, implemented by some reactors, allows adding an existing established connection to the reactor. Starting with the release after 12.2, Twisted will begin requiring zope.interface 3.6 (as part of Python 3 support). This is the last Twisted release supporting Python 2.6 on Windows. For more information, see the NEWS file here: http://twistedmatrix.com/Releases/Twisted/12.2/NEWS.txt Download it now from: http://pypi.python.org/packages/source/T/Twisted/Twisted-12.2.0.tar.bz2 or http://pypi.python.org/packages/2.6/T/Twisted/Twisted-12.2.0.win32-py2.6.exe or http://pypi.python.org/packages/2.6/T/Twisted/Twisted-12.2.0.win32-py2.6.msi or http://pypi.python.org/packages/2.7/T/Twisted/Twisted-12.2.0.win32-py2.7.exe or http://pypi.python.org/packages/2.7/T/Twisted/Twisted-12.2.0.win32-py2.7.msi Thanks to the supporters of Twisted and to the many contributors for this release. -- Ashwini Oruganti

Cython 0.17 released
by Stefan Behnel 01 Sep '12

01 Sep '12

Hello everyone, on behalf of the Cython project team, I'm proud to announce the final release of Cython 0.17. This is another major step forward in the development of the Cython programming language that will make life easier for a lot of users, rounds up some rough edges of the compiler and adds (preliminary) support for CPython 3.3 and PyPy. It is also the first final release of an implementation of PEP 380 (generator delegation), before it will eventually appear in CPython 3.3. === Download and Documentation === Download: http://cython.org/release/Cython-0.17.tar.gz Release notes: http://wiki.cython.org/ReleaseNotes-0.17 Homepage: http://cython.org/ Documentation: http://docs.cython.org/ === Major features of this release === * vastly improved integration with the C++ STL containers http://docs.cython.org/src/userguide/wrapping_CPlusPlus.html#standard-libra… http://docs.cython.org/src/tutorial/strings.html#c-strings * "yield from" delegation between generators (PEP 380) http://www.python.org/dev/peps/pep-0380/ * alpha quality support for PyPy (via cpyext) http://docs.cython.org/src/userguide/pypy.html === What is Cython ? === Cython is a language with an optimising compiler that makes writing C extensions for the Python language as easy as Python itself. The Cython language is a superset of the Python language that additionally supports calling C functions and declaring C types on variables and class attributes. This allows the compiler to generate very efficient C code from Cython code. The C code is generated once and then compiles with all major C/C++ compilers in CPython 2.4 and later, including Python 3.x. PyPy support is work in progress (on both sides) and is considered mostly usable in Cython 0.17. All of this makes Cython the ideal language for wrapping external C libraries, embedding CPython into existing applications, and for fast C modules that speed up the execution of Python code. Have fun, Stefan
