gchq/CyberChef

CyberChef is a web-based data analysis and transformation tool that provides a modular framework for applying various data operations. The system supports asynchronous processing via Web Workers, handles diverse data serialization formats, and offers a comprehensive library of cryptographic, encoding, and utility operations. It features a modernized, themeable user interface and a robust Node.js API for headless usage.

The project underwent a comprehensive modernization of its build system and architecture, migrating from Grunt and JSHint to Webpack and ESLint while adopting CommonJS modules. This period also involved the removal of legacy CSS, HTML templates, and outdated client-side libraries to streamline the codebase and improve code quality.
