Microsoft Windows Media Player Encryption Hacked

NubKnacker writes "Here we go again. The Register has the story about the encryption in Windows Media Player being hacked by DVD Jon. From the article: 'Jon Lech Johansen has reverse engineered a proprietary algorithm, which is used to wrap Media Player NSC files and ostensibly protect them from hackers sniffing for the media's source IP address, port or stream format. He has also made a decoder available." This has been pending for some time now. Do you see a reason to install Windows/WMP just to be able to view a webcast?"

  1. Why this happens by sdirrim · · Score: 3, Insightful

    You know, this only happens because Microsoft is the industry standard. Imagine a world where there are competitive OS and software markets, with no Internet Explorer phenomenon. You wouldn't get this, because developers would actually try to create secure programs. Instead, Microsoft takes programs that are more or less comparable, and incorporates them into it's products, thus killing any competition for that program! (Read: Excel and Lotus 1-2-3)

      Microsoft is the "industry standard" only because they are big & powerful & have the ability to force others to do things their way. Standards are based upon community support. What DVD Jon is doing is showing that there's little community support for Microsofts so-called "standards".

      Ok, maybe I'm just stupid ignorant, but I haven't found a way to record Windows Media streams to my HD to watch again later. Maybe it's there and I'm such a git I can't find it. But if it's not there, maybe one reason why is to prevent people from doing that very thing. Nothing like a proprietary format to ensure you only get to see what the provider wants you to see and when they want to make it available to you.

    What this does is simply to take one of those files with meta info about a stream and translate it to a human readable format. The meta file looks like this:

    That's why I'm willing to use it. Looks a bit blocky, but compresses incredibly well - I have a wmv music video that's smaller than an mp3 of the song in question. Also, I've found it the easiest of the main video formats (windows media, real, and quicktime - ogg theora and dirac just aren't ready for primetime yet) to get working in linux - just dump the dlls in the right format and both xine and mplayer can play them flawlessly, even as streams from websites (just install gxine or kaffeine). Real is harder, at least if you don't want to use their OSS-only official client, and quicktime is an absolute nightmare. So I'm all in favour of requiring windows media player to view videos, because the alternatives are worse.
