    Yeah, it appears that the license server needs either headers or a payload of some sort.

    Can you post the entire request?

  4. Thank you Karoolus,
    Did you need data plus params for the request?
    I have some videos without the keys. Is there any way for me to get the keys?

    WKS Keys with working L3 CDM

    unzip to folder
    open cmd or powershell in the folder
    run "py l3.py"
    enter PSSH
    enter License URL (the long one, with kid and session)

    That's it

  6. I have this video https://jfc.org.il/en/movie/57746-2/

    The site doesn't require registration so you can easily verify my data by yourself.

    its mdp (if needed): https://d2148dkxdf27z.cloudfront.net/media/Fp8Mo2cCRFOPo/cdc70b58/stream.mpd

    PSSH: AAAAUnBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAADIiKnZkb2 NpcGhlcjoxYWZlYjEzY2E4MWE0NjY1YTA3MDdhZjc1ZTllN2Mx ZEjj3JWbBg==

    (it was specified inside the mpd)

    License URL : https://license.vdocipher.com/auth


    The thing is this site uses advanced Widevine scheme:
    2 requests to license server with headers + json

    So I am trying to implement it in the python code of l3.py

    1) The first request to license server has JSON:
    {"token" : challenge }

    in code it is: wvdecrypt.get_challenge()

    1.2) then I get the response of license sever with JSON:
    {"license" : response}

    in code the response is assigned variable to wvdecrypt.get_challenge()

    I'm now struggling with this step 2.1:

    2.1) Then the second request to license has JSON:
    {"token : some mix of the first token and additional information}

    I don't know how to generate this token in 2.1

    2.2) And as a response it receives JSON:
    {"license" : final_response}


    I also tried to use data from my browser. From it I took token from step 2.1 and sent it as a first request in the script. I got the same response as my browser gets from the second request (2.2) BUT it seems that it somehow checks that sessions are different.

    Please, give me a hint on what I do wrong or how to generate the token in 2.1 based on the license response from 1.2

    P.S: I have working CDM key, don't worry about it

    Thank you very much

    You generated a key using KeyDive, then used another tool (N_m3u8DL-RE) to download it? The website thinks the tool is actually a device with L3 certificate so it allows you to capture it?
    L3 isn't limited to 480p only?

    Keydive is for extracting CDMs out of Android devices, not for grabbing decryption keys. Read the sticky threads in this section of the forum if you're confused.

  22. it depends on the sites...some sites allows you to download 1080p or 720p...with L3 CDM

    for your site I have only this...

    I just had a quick look at some of the sticky threads but I was not able to find the definition for CDMs
    Widevine-L3-Decryptor doesn't work anymore? I couldn't find it.

    Yeah, they didn't upload 720p/1080p. Shame. still worth watching it as I missed the actual event.

    CDM = Content Decryption Module: https://forum.videohelp.com/threads/404994-Decryption-and-the-Temple-of-Doom Basically it's the component that receives the decryption keys for a given video.

    If you mean the Chrome extension, then no, it doesn't work anymore because the old ChromeCDM was deprecated.

  27. Hi there

    -- EDIT 14/04/2024 --
    actually started a new thread

    I need help understanding how to retrieve a drm decrypt key. (all URLs at the end)

    If I should rather start a new thread, please let me know. Also note that I'm a total newb at this.

    I've read threads about KID, PSSH, licence URL and so on, but for the life of me I can't figure out how to assemble these bricks for this particular source.

    What I've done so far :

    - found the MPD url and downloaded the manifest XML.

    - Also downloaded the desired (encrypted) audio and video streams using yt-dlp.
    These are already sitting on my disk now I want to decrypt these using mp4decrypt.

    - didn't find any PSSH nor explicit licence url, so I just tried out some random things :
    I went to cdrm-project.com and entered the url found at "keyUriTemplate" in the manifest XML (first one for audio, along with its kid param.) and some headers that I could make out, leaving the PSSH field blank.

    Upon "Send" it returned :
    Code:
    Cached PSSH
    
    PSSH:
    
    Time:Wed Jan 3 17:08:02 2024
    
        b8d35746ec9e9f5c3ebfc5ec945ebf42:78531faef00ddfcf9dfe029812c9f40f
    Now this is where I'm stuck. I have no idea what to do now (this obviously not being a drm key...)

    Any help would be appreciated. (I'd rather learn how to finalise this by myself than to just get the key, you know, the "teach how to fish..." spirit)

    MPD URL :
    https://appiniummediacentralusa-usct.streaming.media.azure.net/02f4acb1-7193-422d-8d0f...ncryption=cbc)

    Headers I used on cdrm-project :
    Code:
    accept: "*/*"
    Accept-Language: "fr,fr-FR;q=0.8,en-US;q=0.5,en;q=0.3"
    Accept-Encoding: "gzip, deflate, br"

    Connection: keep-alive
    Referer: "https://community.claris.com"

  28. Of course it's a decryption key, you can decrypt your media using:
    Code:
    mp4decrypt --key b8d35746ec9e9f5c3ebfc5ec945ebf42:78531faef00ddfcf9dfe029812c9f40f in.mp4 out.mp4
    Please note that a cached PSSH might not always work.

    Just looked into your MPD manifest and i think you've encountered a rare occurence of AES-128 encryption using a DASH manifest file (.mpd), which doesn't make sense because i think AES-128 keys have a different format.

    I tried around and wasn't able to decrypt it, might be worth to open up a new thread.

  29. Yes because of course I tried using it as a decryption key exactly as you wrote it. Should have mentioned it, sorry.

    But it results in a 0 bytes decrypted file with no error message whatsoever.

    There's just a little satisfaction in the fact that I was not completely off the mark ��

    Thanks for trying it out.
