This part is weird to me. My understanding is DRM lock the file at a per user level, so the DRM encrypted chunk would be different from yours. Unless for all bitrate, and for all streaming format, Netflix has already pre-computed everything. Otherwise, there must be some sort of pre-computation before it can be served over TLS.
- wmf 4y agoThat's not how DRM works. The content is encrypted once and that key is sent to the client. The content key is probably wrapped in some per-session key (which may be wrapped in a per-user key wrapped in a per-device key or something).
