Al Qaeda improves encryption
Network World says al Qaeda is encrypting chat rooms with open source RSA code.
Tampa-based ISP NOC4Hosts and Rochester, Minn.,-based SiteGenesis in January found out their operations were being used to host the Al-Ekhlaas Web sites where Mujahideen Secrets 2 can be found. Both hosting firms pulled the plug on the Web sites after receiving specific technical information about the content. ...
Another notable thing is that the public-key signature in Mujahideen Secrets 2 leaves a tell-tale sign that the Al-Ekhlaas home-rolled software produced it. The encryption itself is strong at up to a 2,048-bit key length, and like the previous version, provides e-mail and file encryption using public-key certificates.
