The majority of media-based DRM implementations are completely bunk and fundamentally broken. You — yes, you, reader — are able to take advantage of DRM implementations and break their fundamental premise without much effort
But, apparently not Widevine and not the kind of HN reader who wrote the article. They spent weeks trying to extract the key and failed. The article is a story of their failure.
- joshmn 5y agoThat's one way of looking at it. Who says you need to extract the key for playback?
- native_samples 5y agoThe thing with the key is also checking if you're licensed, and negotiating with the OS/GPU/display device to prevent you from screen recording it. So the key isn't useless. It doesn't stop you from pointing a camera at the screen and recording it that way, but stuff like Cinavia can stop that too. So, the key does matter.
