C# console app to download DRM protected videos from Onlyfans accounts
I have tried to make this a lot more simple to set up compared to OF DL.
The only thing you need to do is go to the releases page and download the latest release zip file.
Extract the zip file somewhere safe using 7zip or winrar, you should have 3 files and 2 folders:
- OF DRM.exe
- auth.json
- e_sqlite3.dll
- EXEs - this contains yt-dlp.exe, mp4decrypt.exe and ffmpeg.exe with the paths already set up correctly in the auth.json file. DO NOT TOUCH THEM IF YOU DON'T KNOW WHAT YOU ARE DOING!
- cdm - this is where you need to put your device_client_id_blob and device_private_key files. They need to be placed in
cdm/devices/chrome_1610/.
Next you need to fill out the auth.json file.
- Go to www.onlyfans.com and login.
- Press F12 to open dev tools and select the 'Network' tab.
- In the search box type 'api'
- Click on one of the requests (if nothing shows up refresh the page or click on one of the tabs such as messages to make something appear).
- After clicking on a request, make sure the headers tab is selected and then scroll down to find the 'Request Headers' section, this is where you should be able to find the information you need.
- Copy the values of
cookie,user-agent,user-id(this should just be a number, do not include au) andx-bcto theauth.jsonfile where the paths to yt-dlp, ffmpeg and mp4decrypt should already be. - Save the file.
You should have something like this:
"USER_ID": "123456789" - Do NOT include the u that gets exported using the Onlyfans Cookie Helper
"USER_AGENT": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/112.0.0.0 Safari/537.36" - Make sure this is set to your user-agent value
"X_BC": "2a9b28a68e7c03a9f0d3b98c28d70e8105e1f1df" - Make sure this is set to your x-bc value
"COOKIE": "auth_id=123456789; sess=k3s9tnzdc8vt2h47ljxpmwqy5r;" - Make sure you set auth_id to the same value as user-id and that you set your sess to your actual sess value, everytime you log out of Onlyfans this value will change so make sure to update it after every login.
Next you will need to get 2 files, device_client_id_blob and device_private_key. These are used to get the decryption keys needed for downloading DRM videos. You can find a tutorial on how to do this here https://forum.videohelp.com/threads/408031-Dumping-Your-own-L3-CDM-with-Android-Studio
Make sure you remove the file extensions when renaming the 2 files, and move both files into cdm/devices/chrome_1610/.
Once you have filled all of the information out you can close auth.json and double click on OF DRM.exe and you should be ready to start downloading videos.
This scraper is aimed to download DRM videos only and nothing else.
