DVD CSS Decryption
The CSS (Content Scrambling System) is the encryption method used in
commercial DVD production to prevent DVD data from being copied.
Stated another way, CSS (Content Scrambling System) or ARccOS
decryption is used to prevent the illegal copying of DVD movies (e.g
those who rent and copy). The sole purpose of the CSS is to protect
copyrights by preventing the pirating of DVDs.
The CSS decryption, called DeCSS (De-Content Scrambling System) is an
algorithm that can be used to decrypt a commercially-produced DVD,
allowing it to be unlocked then copied. In January, 2000, the
development of DeCSS was blamed on Jon Johansen, a fifteen year old
boy from Norway. Charges against Jon Johansen were dismissed in
January, 2003.
DeCSS is used by several DVD copy software manufacturers to decrypt
DVDs; some include it with the software, others require you to
download the algorithm from the internet before the software will
work.
Some DVD Burning Software has this decryption build in (which may be
ruled illegal in the future) while others download (one time) the
decrypter from a 3rd party source (which seems to be the safer legal
way).
