HDCP broken

There's an XKCD for every occasion

Great news for digital restrictions management (DRM) opponents everywhere, HDCP has been broken! HDCP is basically the encryption used along HDTV lines, which prevents unauthorized receivers from viewing content. Since the crack, HDCP no longer guarantees that participating devices are licensed, because a maker of unlicensed devices can use a key generator to create mathematically correct public/private key pairs. If you’re wondering why said encryption is a bad thing, why should a cable that you owned, connected from a box you own to a display you own have its content encrypted so that you can’t record it?
