rlaphoenix 3ef69deb29 docs: Remove the Protocol from README
There's no need for it. The image isn't even done particularly well. It's too specific to a browser scenario with some information not properly reflected/explained in the legend.

I have no reason to try make my own or look for an alternative. If someone is particularly interested they can look online for more or less broad explanations as they see fit.

rlaphoenix 1156edfef7 deps: Update lxml to >=4.9.1
This is to fix some security vulnerabilities. The main dependency locking this to 4.8.0 for so long was pycaption, which was updated to support 4.9.1 in v2.1.0.

rlaphoenix 362510de68 Device: Re-raise DecodeErrors within some DecodeError handlers 2022-09-05 12:55:06 +01:00
rlaphoenix fa499a6a53 Improve verification of proto parsing across Cdm, RemoteCdm and Device
This ensures that a partially parsing input (because of optional flags in the proto) does not get past any verification checks.

This prevents issues like an invalid License Challenging from getting an exception later down the line, as well as possibility of it also passing that check by pure luck, resulting in hard to debug issues.

rlaphoenix 23c766af71 Cdm: Improve accuracy of OEMCrypto request_id research
The main change is that it isn't stored as 16-bytes. Effectively not stored like it realistically probably meant to be. It's instead stored as a hex string that was then encoded to bytes (32 data is now taken up).

But I've also improved the comments about my research for the first half of the request ID. This research is likely still incomplete as I'm just not fully sure about the randomness of bytes 5-8.

rlaphoenix 2af929a83d Cdm: Use reversed OEMCrypto request id formula for Android devices
It's effectively 8 random bytes with a counter thats right-padded (to 8 bytes). This counter is the Session number.

rlaphoenix 2179987986 RemoteCdm: Remove all uses of Session()
This is now possible because everything relating to an underlying session is now finally fully remote thanks to the changes surrounding the new get_keys() method.

Any client code still getting keys by accessing `_sessions` manually should be updated to use the get_keys() method.

rlaphoenix 6eceaaf410 serve: Remote TODO that will not be done
We shouldn't really provide the derived context keys. There isn't any use to them outside of that specific license request and license response for which it was derived from. The only use to them would be to allow the client to decrypt the keys manually, which wont be necessary nor secure.
