Decryption and the Temple of Doom

[JackGPT]

This section is relevant for both methods of obtaining a CDM

So I checked my keys were working there;-

https://bitmovin-a.akamaihd.net/content/art-of-motion_drm/mpds/11331.mpd

this link loaded in a browser will show PSSH keys between <cenc: pssh> html markup and

https://cwip-shaka-proxy.appspot.com/no_auth

is the license. Edit: 2 Oct 2022 this URL has changed since March and the correct version is above.

Thanks for that
Now I can obtain my CDM and use L3
but there are some websites I can't find license link that are similar that

is there a solution ?

Searching for the license is hard on some sites. That's just part of the game we play. Look for a POST request in the network tab and try a filtering on 'widevine' 'authority' 'acquire' and variations of, as well as 'licence' Sometimes you may need to refresh the page a few times 'shift + refresh' or 'ctrl + R' before the licence appears.

On my case I need to download from VdoCipher and inkryptvideos but I have been told that my CDM is old and I need to obtain new one from android 12 as I had one from android 9
VdoCipher and inkryptvideos don't show in their license link that forms
the only show token only

vdocipher uses a unique id formed from parts of the mpd to act as a pseudo-pssh - I understand from others - no direct experience myself

I have good news for you! Look here https://forum.videohelp.com/threads/409682-Keys-Found-from-a-Database-Search#post2693702 for vdocipher keys

If you want more help on the sites you mention, better to ask in the main forum - this thread is for beginners and won't get much traffic.

Wonderful and easy to follow guide; thanks a bunch!

[TangoInTheDay]

Thank you so much! Got it working with an emulator.

Seeking help with an error using l3.py. Running on Windows 8 (yeah, yeah, it is what it is for now)...

I can generally follow along but the Python errors are kind of all Greek to me...

- A very gracious member helped me get a CDM
- Downloaded WKS-KEY and unpacked it
- Renamed the CDM files and replaced them in the correct WKS-KEY directory

- Using DevTools, I believe I found the license URL, headers (put into headers.py) and the PSSH key (<cenc:pssh>...</cenc:pssh>) from .mpd file

- Did not have Python, downloaded and installed latest Python 3.11.4
- Some modules needed for l3.py when I try to run it, so I need pip
- Downloaded https://bootstrap.pypa.io/get-pip.py and then py get-pip.py
- Path is correctly updated with /Python311 and /Python311/Scripts, so restarted laptop
- pip install requests
- pip install xmltodict
- pip install google
- pip install google-api-python-client

All said successfully installed, and then this is the error I'm currently seeing trying to run py l3.py:

Traceback (most recent call last):
  File "C:\key\main\l3.py", line 9, in <module> from pywidevine.L3.cdm import cdm, deviceconfig
  File "C:\key\main\pywidevine\L3\cdm\cdm.py", line 10, in <module> from pywidevine.L3.cdm.formats import wv_proto2_pb2 as wv_proto2

  File "...\Python311\Lib\site-packages\google\protobuf\descriptor.py", line 796, in __new___message.Message._CheckCalledFromGeneratedFile()
TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

More information: https://developers.google.com/protocol-buffers/docs/news/2022-05-06#python-updates

Wondering if I should use a different version of Python? If anyone has any insight on this, I'd appreciate it, and thank you very much in advance!

pip remove protobuf
pip install protobuf==3.20.3

[DigitalArchive]

pip remove protobuf
pip install protobuf==3.20.3

Thank you! Worked with uninstall

Now I get:

> py l3.py
...
cdm.py, line 13
from Cryptodome.Random import get_random_bytes
ModuleNotFoundError: No module named 'Cryptodome'

> pip install Cryptodome
...
ERROR: No matching distribution found for Cryptodome

From Google I am seeing that get_random_bytes may be part of some other packages, that is assuming it's the same function and will be compatible, but if I download a different package, do I need to then edit cdm.py?

[A_n_g_e_l_a]

pip install cryptodomex. Don't ask me why?

[DigitalArchive]

pip install cryptodomex. Don't ask me why?

Hmm it didn't want to work for me... I guess I will Google some more...

Got it lol

> pip install pycryptodomex

[A_n_g_e_l_a]

pip install pycryptodome. Sorry memory issues. same for pycryptodomex should you need it

Next time google 'python provides cryptodome' to avoid VH dependency.

When I type python3 l3.py in WKS_KEY folder, I receive
from pywidevine.L3.cdm import cdm, deviceconfig
ModuleNotFoundError: No module named 'pywidevine.L3'


Obviously, the folder pywidevine is here.

Any workaround to fix that?

i faced this problem
how i solved it - pip uninstall pywidevine

protobuf==3.19.5

latest of the 3 series protobuf is my normal recommendation.
pip install protobuf==3.20.3

Good that you did it yourself. Pywidevine and WKS-KEYS do not play nicely together.

Does the processor of the Android TV Box matter? There are really cheap units on Amazon like this one, with Android 12
The one mentioned in 1st post T95 S1 is only Android 7.1 (so likely that some sites would not play nicely I suspect)

Yes, it matters in that the Android version will have function names for dumper to hook that are unknown. You can find them by inspecting libvwhidl.so but it is more complex than using the Android 7 box and beyond the scope of this guide.
However there is more help here https://forum.videohelp.com/threads/407196-Dumping-L3-from-Android-10-11-and-12; it applies generally to more modern devices.

How Do I fix this?

How Do I fix this?

Send the full error including the strings you put into wks-keys.
Most likely an issue with the data you entered

[A_n_g_e_l_a]

code :


How Do I fix this?

You look at the error message 'int object not iterable'. The program is expecting a list and it got a single number. My guess 403
Also my guess you decided to go for the hard ones first. Ask in the general forum for easy sites in your country and try those first to get the process sorted.

And next time you ask for help remember people cannot read minds. Say what you were doing, and what your inputs were, to get the output you've rather unnecessarily copied.

ok got a little problem, when I try to use the "dump_keys.py" it just opens and it automatically closes. When I open up cmd in the dump keys directory and type in python3 dump_keys.py in the cmd, it says "Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Manage App Execution Aliases." Is there a way to fix this please?

Install python?
If it's already installed, try reinstalling it

[HJPM]

Got keys from android studio, don't understand this step:

"Now, in theory you have a working CDM and can generate your own keys. I found an encrypted video to download, located the request headers saved as a cURL and encoded intp python here:- https://curlconverter.com/"

And don't know how to proceed.
