Message Encryptor & Decryptor

Securely encrypt and decrypt messages using a secret key.

Message Encryptor & Decryptor is a lightweight Chrome extension that allows you to securely encrypt and decrypt text using strong modern encryption directly in your browser. This extension uses the native Web Crypto API (AES-GCM with PBKDF2 key derivation) to ensure your messages remain private and secure. All operations happen locally on your device — no data is sent to any server. Why install this extension? • Encrypt sensitive text instantly • Decrypt encrypted messages securely • Password-based protection (no hardcoded keys) • Fully offline — zero data collection • No permissions required • Fast and lightweight • Clean and easy-to-use interface How it works: Your password is processed using PBKDF2 (SHA-256, 100,000 iterations) to derive a secure key. Each message uses a random salt and IV to ensure strong encryption. The output includes the necessary encrypted data encoded in Base64 format. This extension does not collect, store, or transmit any personal data.
