After DeCSS, DVD Jon Releases DeDRMS

Posted by timothy on from the one's-right-to-annoy dept.

An anonymous reader writes "Jon Lech Johansen, who reverse engineered FairPlay back in January, and wrote the decryption code that was later used by an anonymous developer to create the playfair utility, has released a similar utility: DeDRMS. It's only 230 lines. T-shirts anyone?"

      # is the "hash" symbol. C#, while written out as "C Hash", is pronounced "Cash", reflecting the reason Microsoft invented it.
