This page contains mostly technical and historical information about both CSS (the "encryption") and DeCSS (the decryption tool).

C'est aujourd'hui même qu'on se bat pour le droit de lire. Bien que cela puisse prendre 50 ans pour que notre façon de vivre actuelle s'efface dans l'obscurité, la plupart des lois et pratiques décrites plus haut ont déjà été proposées ; plusieurs ont force de loi aux USA et ailleurs. Aux USA, la loi dite DMCA² de 1998 a établi la base juridique pour restreindre la lecture et le prêt de livres numérisés (et d'autres données également). L'Union européenne a imposé des restrictions similaires dans une directive de 2001 concernant le copyright. En France, avec la loi DADVSI, la simple possession d'une copie de DeCSS, le programme libre permettant de déchiffrer une vidéo sur un DVD, est une infraction.

A propos de copy-rights ; je serai plutôt pour le copy-left évidement :)!

Hacking CSS

The media generally refers to Jon Johansen as the one who cracked CSS, though this might not be so. In fact, the late DeCSS releases by MoRE ("Masters of Reverse Engineering") contain a text file that says quite the contrary: An anonymous german hacker was responsible for the CSS crack, and MoRE only claims credit for writing DeCSS, the software. Jon Johanson said the same again in a recent interview with LinuxWorld.
MoRE also mention Derek Fawcus, who used to have a site with a cryptoanalysis of CSS at http://www.eyrie.demon.co.uk/css/, though that site has been down for a long time now.
Frank A. Stevenson had his cryptoanalysis of CSS online at crypto.gq.nu for a much longer time. The site still contains a link to it, and in case that ever vanishes, I have also a local copy.
The links section shows clearly that CSS source code was posted anonymously to the LiVid mailing list on october 25th, 1999. Stevenson posted his first attack on the cipher two days later.
MoRE claim that they had working CSS decryption code in the middle of september, 1999.
DeCSS, the proof-of-concept software that includes the CSS decryption code, was released in later october, 1999. MoRE also claims that another group, Drink or Die (DoD) also had a working decryption tool. That brings the total count of independent groups breaking the CSS encryption to three.'
