I'm listening now to Chaos Radio 111. At the studio are Frank Rosengart, hukl, Harald Welte and of course Holger Klein.
The topic is about
cryptography
and how to crypt your hard disc and your data to be secure.
Within this there were some users who asked about WLAN security and the policy of the police.
There exist also a
Contribute page on Wikipedia.
Really good show. There exist no longer any fact to not crypt any of your data.
