One for email

The Firefox plug-in Freenigma is an e-mail encryption tool that can be used in a whole range of Web email systems - including Gmail, Yahoo!Mail and Hotmail/MSN.
Developed by freiheit.com, Freenigma came out of public beta at the end of September.

“Today, all your e-mails are stored and sent around the planet in plain text. And today you have no control over what happens to your private or business e-mail conversations and you can’t prevent others from reading them. Get your privacy back! Encrypt your private and business e-mails to protect your freedom, privacy and your business secrets.”

The advantage of being browser-based, is that it runs on all the main OS platforms - Linux, Mac or Windows XP. It uses one of the most famous and most widely used cryptographic software packages in the world: the GNU Privacy Guard (GnuPG). Werner Koch, developer of GnuPG, is a founding member of freenigma along with Stefan Richter.
The FAQ

One for the developers

While developing an online voting system in Germany, Micromata invented a component for secure PIN/password input via untrusted, insecure browsers, called Transec.
Micromata has just released this secure authentication input module under GPL.

Spyware in the form of Browser Helper Objects and keyloggers can capture user keyboard input even if it is encrypted. As spyware attacks the Browser implicitly all the data entered by a regular user on a web page could be accessible for a third person.
This is why Transec enables user authentication using 100% server-side control. The entire input field is generated on the server. The only interaction between the user and the server is the transmission of pictures and the coordinates of mouse-clicks.
The Java code and a demo application are available at the Transec homepage. Freely embeddable, Transec can be redistributed for non-commercial projects; a commercial license is also available.
