WHOOKIDSON: what are you looking for? Can you get the new fairplay keys? the old play ready is easily available. If you blank the MediaServer Validation policy and UVD downloads the correct key. You can also grab if from memory.

I wrote a little piece of code to verify the Content Key against the KeyID with the playready header checksum. This will allow you to know if you have the correct key for a given KeyID.

I have been using it to check for correct key responses.

from Crypto.Cipher import AES
import base64

def keyChecksum(key,keyID):
    encrypter = AES.new(key, AES.MODE_ECB)
    encData = encrypter.encrypt(keyID)
    return base64.b64encode(encData[:8])

The only thing that is post-abled from UVD from the new videos is the mangled key url from the original "skd://netflix/" value. Like I said that is just a value from the pssh box atom in the mp4. It is in the clear in the file. It is drm specific info to get the key and not the key itself.

Do you know how the streaming key delivery functions? I hooked into to several functions to follow the processing of the "skd://" fairplay response. The response was rather large.
