PSA: Help with DRMToday

[bengalih]

I just wanted to post a quick PSA/consolidated little helping tutorial as I struggled with this for a couple hours the other day.
I want to thank the mentors on the site as I went from knowing virtually nothing about how to download DRM content (outside of all-in-one tools) before this afternoon and spending a couple hours here and on some other sites I was successfully able to get my content.

I struggled for a while as the content I was trying to access was licensed by the following URL:
https://lic.drmtoday.com/license-proxy-widevine/cenc/

I successfully grabbed a set of CDM keys using the stickies in this forum but tried several tools like WKS-KEYS as well as some other L3.py scripts I found here and on other sites but nothing was working for me. I realized that the issue must be with the headers and specifically the x-dt-auth-token, but try as I might I wasn't able to generate a key.

I had also tried on https://cdrm-project.com/ to get the key inputting in the header info and was unsuccessful. However, after my successful attempts using @karoolus DRMToday script, I was somehow able to also get a proper response on cdrm as well, so I'm not sure exactly what I was doing wrong there.
(It might have been specifying https://lic.drmtoday.com/license-proxy-widevine/cenc/?specConform=true as the license server instead of just https://lic.drmtoday.com/license-proxy-widevine/cenc)

Once I found @karoolus script, I still was having issues with dependencies on my Windows box (which was successfully running the other l3 scripts I was trying). I was getting dependency errors. This was most likely due to how my python environment was setup after installing dependencies for other scripts. Anyway, I found some help in this post here regarding the bare minimum required for DRMToday.

Using that, I would recommend if you have any issues with DRMToday that you go ahead and create a Python virtual environment, activate it, and then install just what is required. Here is a snippet of how to perform this:

python -m venv DRMToday
DRMToday\Scripts\activate
pip install pycryptodomex==3.15.0
pip install protobuf==3.20.3
pip install requests==2.28.1

First line creates the venv, second makes it active, and the next 3 lines install the required dependencies via pip. Then the DRMToday.py script should run no issues.

Hope this helps someone!

i try this script and then show pssh and token, i have pssh but where i get token?

Glad you got it to work, but I won't claim that script. I found it floating around and posted it here. I didn't write it!
Credit where credit's due, and it's not for me.

As for DRMToday system, this so-called "TOKEN" probably refers to something like "dt-custom-data" or "x-dt-auth-token".
You should try searching in the network traffic and see if there's anything like this.
