Message Encryptor

Securely encrypt and decrypt messages and files using AES-GCM — fast, offline, and private.

Message Encryptor is a powerful and privacy-focused Chrome extension that allows users to securely encrypt and decrypt messages and files directly within the browser. Built using the Web Crypto API, it implements AES-256-GCM encryption with PBKDF2-based key derivation to ensure strong, industry-standard security. The extension provides a modern and intuitive interface with dedicated tabs for message encryption/decryption, file encryption, and activity history. Users can input text or upload files, protect them with a password, and generate encrypted output that can be safely shared. Advanced features such as optional compression, digital signing, and multiple output formats (Base64/Hex) enhance flexibility and usability. All operations are performed locally in the browser, ensuring that no data is transmitted to external servers. The extension also includes clipboard copy functionality, export options, password strength indicators, and secure random generation for salts and initialization vectors. Message Encryptor is ideal for developers, security professionals, and everyday users who want a fast, offline, and reliable way to protect sensitive data.
