ANN: A new version (0.2.4) of the Python module which wraps GnuPG has been released.

A new version of the Python module which wraps GnuPG has been released. What Changed? ============= This is a minor enhancement release. See the project website ( http://code.google.com/p/python-gnupg/ ) for more information. The current version passes all tests on Windows (Python 2.4, 2.5, 2.6, 3.1, Jython 2.5.1) and Ubuntu (Python 2.4, 2.5, 2.6, 3.0, Jython 2.5.1). 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.

[ANN] argparse 1.1 - Command-line parsing library
by Steven Bethard 01 Mar '10

01 Mar '10

======================= Announcing argparse 1.1 ======================= The argparse module provides an easy, declarative interface for creating command line tools, which knows how to: * parse the arguments and flags from sys.argv * convert arg strings into objects for your program * format and print informative help messages * and much more... The argparse module improves on the standard library optparse module in a number of ways including: * handling positional arguments * supporting sub-commands * allowing alternative option prefixes like + and / * handling zero-or-more and one-or-more style arguments * producing more informative usage messages * providing a much simpler interface for custom types and actions Download argparse ================= The argparse homepage has links for source, MSI and single file distributions of argparse: http://code.google.com/p/argparse/ About this release ================== This is the final release of argparse before its move to the Python 2.7 and 3.2 standard libraries. Major enhancements in this release: * ArgumentParser(..., version=XXX) is deprecated. Instead, you should use add_argument(..., action='version') which is more flexible and does not force you to accept -v/--version as your version flags. * Usage and help (but not version) messages are now written to stdout instead of stderr, consistent with most existing programs. * User defined types passed as a type= argument can now raise an ArgumentTypeError to provide a custom error message. * Namespace objects now support containment, e.g. "'foo' in args". Various bugs were also squashed, e.g. "from argparse import *" now works. See the news file for detailed information: http://argparse.googlecode.com/svn/tags/r11/NEWS.txt Enjoy!
