## Description

DeDRM_tools is a software suite designed to automate the removal of digital rights management from personal e-book files. By stripping restrictive encryption layers during the import process, the utility enables users to manage their digital libraries and convert protected files into open formats for use across various reading devices.

The system operates through a modular architecture that utilizes plugin-based event interception to hook into host applications. It performs cryptographic key extraction by scanning local configuration files and memory, applying algorithm-specific decryption to unlock content. All processing occurs entirely on the user's local machine, ensuring that sensitive keys and protected files are never transmitted to external network servers.

The project provides a comprehensive framework for digital library interoperability, supporting the management of personal collections by removing access controls. It is distributed as a set of scripts that integrate with existing e-book management software to facilitate automated decryption and format conversion.
