Secure instant messaging tool
Germany is often at the forefront of online security and whistle.im is a German service dedicated to ensuring you can chat securely online. Whistle.im claims it is suitable for anyone ranging from businesses to private users and whistle-blowers or those "just wanting to talk dirty with their boyfriend/girlfriend". The security of the system is based on the fact that not even the developers claim to know how to intercept messages. At the moment, whistle.im is in Beta so expect some teething issues but its an interesting project for anyone worried about security when communicating online.
