# OF-DRM
C# console app to download DRM protected videos from Onlyfans accounts
## Installation
We have tried to make this a lot more simple to set up compared to `OF DL`
> [!NOTE]
>
> The only thing you need to do is go to the [releases][1] page and download the latest releases 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 [^1]
- cdm [^2]
### 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
you will need to get 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][2]
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.
## Config Values
`DownloadPaidPosts`:
If set to `true` then any posts on the users feed that have been purchased by you and have DRM enabled videos will be scraped.
If set to `false` no paid posts will be scraped.
`DownloadPosts`:
If set to `true` then any posts on the users feed that have DRM enabled videos will be scraped.
If set to `false` no posts will be scraped.
`DownloadArchived`:

`DownloadPaidMessages`:

`IncludeExpiredSubscriptions`:
If set to `true` then any past subscriptions that aren't currently active are included in the list of accounts you can scrape.
If set to `false` then any past subscriptions are excluded from the list of accounts you can scrape from.
`DownloadPath`:
If left blank then content will be downloaded to `__user_data__/sites/OnlyFans/{username}`
An example is if you set the download path to `"S:/"` then content will be downloaded to `S:/{username}`
### Credits
[Thanks to sim0n00ps][3]
[^1]: 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!
[^2]: 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/`.
