C# console app to download DRM protected videos from Onlyfans accounts

OF-DRM

C# console app to download DRM protected videos from Onlyfans accounts

Installation

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.

1. Go to www.onlyfans.com and login.
2. Press F12 to open dev tools and select the 'Network' tab.
3. In the search box type 'api'

4. 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).
5. 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.
6. Copy the values of cookie, user-agent, user-id (this should just be a number, do not include a u) and x-bc to the auth.json file where the paths to yt-dlp, ffmpeg and mp4decrypt should already be.
7. 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.

Videos

This scraper is aimed to download DRM videos only and nothing else.

You will get the choice to:

• Download None of the videos found
• Download All of the videos found
• Select individual videos found, you will be able to see the Post/Message Id along with DateTime of that Post/Message.

To navigate the menu the can use the ↑ & ↓ arrows, to select/deselect video(s) press the space key and after you are happy with your selection(s) press enter to start downloading.

of-drm's Issues

Instant Crash

I noticed today when I open the program it instantly closes without giving me time to read anything. It worked perfectly fine before. I don't understand

An exception?

Hello I'm not really sure what this means. I placed the 2 files in the folder as requested and checked all the values and it automatically closes but says this.

Scrape missing individual DRM video in Messages

There is a single video, sent in messages, not a paid/ppv video, but it was sent in response to a main feed "donation campaign", that isn't being detected by OF-DRM. It's definitely DRM, Internet Download Manager reads it as Protected as well as a second chrome extension I've had for years.

I was able to download it successfully with OF-DL, so I think there is something about the selection process in OF-DRM that is skipping over it. Really big fan of these utilities; I can provide data from Inspect Elements in the div class="video-js", poster="http://cdn2.onlyfans.com/files/#/##/######", etc. from both the DRM videos it is detecting correctly and the one it is missing if that will assist, but I don't necessarily want to paste them publicly in case any of the data can identify my OF account.

Not working

After i modified the auth.json.. OF website on the browser page logs out automatically and getting "Auth failed, please check the values in auth.json are correct, press any key to exit" error on the app.

i relog again and re-edit with the latest session string on the auth.json but still getting the same error above... hmmmm

How to specify a download path?

I want to specify a specific folder for downloaded videos. How can I do this?

Downloading purchased videos

Hello is there a way to download purchased videos form my home tab or from messages? IMHO Onlyfans changed something in the last weeks. Anyone have experienced the same situations?

Need help for getting DRM key

Hi,

I followed the guide on getting the drm keys from:

How to use this repo for some MPD file

Hi, I just now found this project, after setting up your other, yesterday... and well, Version 1.7 does cause a (false?)positive hit with windows defender for "Trojan:Win32/Sabsik.FL.B!ml" (a ransomware trojan, apparently) ... 1.6 does not, though?

Problem getting DRM keys

I followed the instructions of Dumping Your onw L3 CDM, everything loads perfectly but the problem is that it is only for previous versions of Android 11, in the tutorial it does it from android 9 and onlyfans does not load in that version, it keeps loading the onlyfans logo without entering the page. I tried it with later versions but the program to obtain the keys fails, in the android 11 version it does not generate the keys but it does not give an error either, could you tell me exactly how you do it to generate the keys please? I swear I'll make it up to you

Android Emulator hypervisor driver is not installed

I get to the point where I need the two files.
But my virtual phone does not boot because the android emulator hypervisor driver is missing, and I have no idea how to fix this problem. The tutorial on the external website is unfortunately quite old and not very detailed.
Is there no way to get the files without having studied rocket science? Maybe with a real Android device?

Issues downloading paid messages

Hi, for some reason, the scrapper is not finding any drm paid messages. And I have two that I've bought that I'm trying to download.

DRM BYpass

Virtual Device Offline

Hey sim0n thank u for your work.

This is concerning getting 'device_client_id_blob and device_private_key', been working endlessly on it.

I can't execute the adb exe because it says "device offline", correctly so since my virtual phone is never booting up when i click Play.

Lmk

After clicking to open, it closed immediately without any error.

After clicking to open, it closed immediately without any error.

All results are zero

I did everything and this is what my results are

Exception caught: Unable to parse license

When trying to download paid posts from messages, I'll get this error:

As you can see, the regular posts download correctly. Any idea what might be causing this?

I normally use OF-DL instead of OF-DRM, but since this specific user has so much content and I only wanted to grab my latest purchase, I decided to try this version.
