The crypto used in 802.11 wireless networking has been cracked. The crack is devastating; it's fast and passive. Simply by listening, the 40-bit key can be cracked in 15 minutes. Worse, the crack scales linearly with the number of bits in the key, so raising the key length to 128 bits would raise the crack time to about an hour. 802.11 is used in such products as the Linksys Etherfast Wireless and the Apple Airport. From now on those products should be considered to be completely insecure.
The battle for unrestricted encryption continues. Professor Bernstein won't rest; he's not going to let this go. More power to him and let's hope he ultimately wins. [He's challenging the US government restrictions on private encryption on free-speech grounds, and so far he's won in every court where the case has been heard. The government has been using delaying actions, and their relaxation of restrictions may partially have been in hopes he'd give up, leaving them still capable of some control. He's not going to, though. He's got blood in his eye, so to speak.]
