# 🛠️ DRM Decryption Guide

Currently, it is not necessary to include the CDM files as it will use non-DRM URLs if possible.

## Decryption Requirements

- **mp4decrypt** (available at [Bento4.com](http://www.bento4.com/)) - Required for the decryption process. This tool should be placed in the `./lib/` directory.

## Instructions

To decrypt DRM content, it's essential to first acquire a CDM (Content Decryption Module). Once obtained, you will need to place the following CDM files into the `./widevine/` directory:

- `device_client_id_blob.bin`
- `device_private_key.pem`

For legal reasons, the CDM is not included with the software package, and you must source it independently.

# 📜 Disclaimer

This tool is meant for private use only. You need a Crunchyroll Premium subscription to access premium content.
