Johansen breaks AirPort Express encryption

Wednesday, August 11, 2004 @ 7:20pm



 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.
