This software implementation, though, looks more like a novelty to prove that the keys are real than a practical anti-HDCP solution. The leak of the master key does allow anyone to create their own sources and sinks, in a manner that cannot be blocked or disabled, so it might yet be used to produce general-purpose HDCP strippers to allow, for example, capture of copy-protected cable programs. So to even get an HDCP-protected stream to use the software with, you need hardware that's able to "speak" HDCP to capture the data-and if you have that, the hardware will be decrypting the stream anyway. With the region is set, anydvd can use the 'normal' method to do it. When the region isn't set, anydvd has to bruteforce crack the keys which doesn't always work. While that is most of them, not all DVD's have CSS. It automatically creates copies and replaces files on the Discs. Ch3vr0n said: Not for all, only for CSS protected discs. This means that the capture device needs to be physically connected to the source (usually over an HDMI, DVI, or DisplayPort cable), and needs to be able to perform the right HDCP handshaking before the source will even begin playback. The software is 100 secure, and there’s no chance of data being stolen. An HDCP source-typically a video card or Blu-ray set-top box-will only transmit data if it can establish an HDCP-protected connection to a sink-a monitor or TV.Īs such, to capture an HDCP-protected data stream, the capture device needs to appear to be a legitimate sink. HDCP is used for the protection of content over the links between systems-for example, the cable between your video card and your monitor-to prevent the creation of perfect digital copies. The purpose of their efforts is less than obvious. In spite of this, the developers believe they have opportunities for further optimization and improvement, making real-time decryption on more modest hardware feasible. HDCP was designed to be cheap and fast for hardware manufacturers, but operations that are quick and easy in hardware are often slow and inefficient in software. The poor performance is due to the nature of the algorithm. The software implementation should be able to decrypt a 1080p30 stream given a suitably fast dual-core processor and about 1.6GB of RAM. AnyDVD HD works in the background to automatically and transparently enable read access of the contents of a movie DVD or Blu-ray as soon as its inserted into the drive. ![]() ![]() Just a few weeks after the leak of the HDCP master keys was confirmed, a software implementation of the encryption scheme has been developed.
