## Description

DeDRM_tools is a digital rights management decryptor and ebook security key manager. It functions as a utility to strip proprietary protections from restricted ebook files, removing vendor lock-in to make the content compatible with any reading application.

The tool manages the decryption process by using a configuration system to store device serial numbers and encryption keys. This allows for the automation of the decryption pipeline across various ebook retailers and platforms.

The project provides capabilities for digital content decryption and ensures ebook format compatibility by processing restricted files into open formats. All cryptographic processing and key matching are performed locally on the user's machine.
