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.

Okay, so he broke the encryption, big deal, what does that mean? I can capture the stream? I can write a custom program that streams music to my speakers?

No, he retrieved the public key that that iTunes uses to SEND music to the AirPort Express. Meaning that any app will soon be able to utilize the Express. This opens the door for Linux users to stream to it as well!

I can't believe Apple hasn't been more open with the Airport Express. Surely it increases the value of the product if there are more possible uses for it. Being able to stream from applications such Videolan would make the Airport Express a much more tempting buy for me. Right now it is a wonderful idea but very limited.

This guy is good. I think Apple should offer him a really good job. It would help them develop linux cross-compatability and it would protect their security if he is able to hack it in R&D. Just a thought.

My guess is he's only against Apple.

I've wanted to use Real Player streaming from the BBC over my Airport Express since I got it, and any step towards this is absolutely fantastic. The same will definitely apply with DVDs and films, sit in bed with my iBook watching a film, and using my speakers without having the cable stretching across the room.

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.
