From BoingBoing comes news that DVD Jon -- famous for breaking the encryption system used on DVDs -- has just broken the encryption method used to stream audio to the Airport Express.

I've released JustePort, a tool which lets you stream MPEG4 Apple Lossless files to your AirPort Express.

The stream is encrypted with AES and the AES key is encrypted with RSA.

AirPort Express RSA Public Key, Modulus:

This gives the ability to 3rd party developers to create streaming tools that work with this device. Although I'm sure that Apple is quickly working on a patch (change the key used) for Airport Express and iTunes to stop said tools from working with its devices.

I say that the AE should have been using open standards to stream the audio in the first place, but that might just be me.
