Johansen breaks AirPort Express encryption
Jon Lech Johnasen, author of DeCSS, has discovered the public key that the AirPort Express uses to allow software to play audio through it. Johnasen says that the audio stream is encrypted with AES and that the AES key is encrypted with RSA. The public key is available on his blog as well as a software application (for Windows command-line) that streams Apple Lossless MPEG-4 audio to an AirPort Express. "Though JustePort is Windows-only software at the moment, it should be only days before graphical software exists for the Mac now that the public key is out in the open. Apple could choose to change it via an AirPort Express firmware update, but it should still be possible to retrieve the new key. This is a huge step forward in giving standard applications the ability to use an Express for audio output," according to one developer.

All this is doing is opening the Airport Express up to more potential customers, and enhancing the experience of those like myself that have already bought it. I'd hope Apple will gradually increase interoperability with Airport Express and Quicktime/DVD Player to make all of their own apps work seamlessly with it, but until then, I am indebted to Mr Johansen.
