Mac GNU Privacy Guard

Updates

20 December 2007: Thanks to Benjamin Donnachie we can finally provide you with a current version of GnuPG (v 1.4.8). You may find it in the Files section.

Also, we celebrate the tenth anniversary of GNU Privacy Guard. Read A Short History of the GNU Privacy Guard by Werner Koch.

13 March 2007: The documentation on how to compile gnupg was updated to reflect the latest version. Also, the introduction which led to confusion when compiling on 10.3.x or lower was revised.

8 March 2007: We finally made it! One year ago Robert Goldsmith thankfully compiled an Universal Binary version of GPGPreferences and made it available as version 1.2.1 in the files section of the project pages at Sourceforge. Unfortunately he catched a buggy version of the german interface. This prevented from promoting this update an this website. Just now there was some time at last to correct that bug and package it again to version 1.2.2. So please refer to the Files section and feel free to download GPGPreferences running both on PowerPC as well as on Intel.

About

Mac GNU Privacy Guard (Mac GPG for short) is, after a fashion, the Mac OS X port of GnuPG, licensed under the GNU GPL. The aims of the project are to make GnuPG easy to install, develop a framework to make it easy for other developers to incorporate GnuPG functionality into their applications, write services to allow for the use of GnuPG functions in most Cocoa applications, and write a Mac GPG Keys type application so that you no longer have to go to the commandline to manage your keys. For those who don't know, GnuPG is a free OpenPGP client (PGP == Pretty Good Privacy). It can encrypt text (usually e-mail or other messages sent between people) and sign text to prove who wrote it. A further discussion of this can be found elsewhere.

Files

To verify each file, either use the detached sig (but DON'T verify GNU Privacy Guard with itself!) or use the provided MD5 checksum. The easy way to do this is at the command line say 'openssl md5 [filename]' where [filename] is the file you downloaded. You should get the same value you see here. If not, something may be up and you should contact the management.

If you intend to verify the MD5 checksum – as you should – and you are using Safari to download the files please make sure that you switch off the option Open "secure" files after download in the general preferences of Safari and that you calculate the checksum on the originally downloaded files.

Mailing Lists

There are several lists associated with Mac GPG, all of which are available to the public. The announce list is very low traffic and will let subscribers know when something big happens, like the release of a new version of Mac GPG. There is also a users list for anyone to discuss the use of Mac GPG and also carries any messages sent to announce. If you are having trouble, this is the place to come. Before posting, always check the archives to make sure that something hasn't already been answered. Also, RTFM. If you are writing code that uses GPGME.framework or are a developer on the project, macgpg-devl is the place for you. And, writing of development, to stay up to date on Mac GPG's development, you may want to subscribe to the commits list, which sends out a message every time something is committed to Mac GPG's CVS tree. If you're interested in helping with translations, you'll want to get on macgpg-i18n.

Contact

You can contact the project at macgpg@zeitform.de, with this public key. Specific developers can be contactacted as listed below.

Development Team

I want YOU In case you haven't figured it out by now, Mac GPG is free software. What this means is that the source code is accessible and free for use by anyone. One aspect of free software is that it is developed openly by a team. If you would like to join the team, send a message to Alexander Nouak (the project's admin), describing how you'd like to help. More than likely, you'll become part of the group. Before you contact me, though, you'll need to make sure that you are signed up with Sourceforge and include your user name in your message. Visit the project page on Sourceforge for more information about the project's development.

You can get all the developers' e-mail addresses and a bit more here.
