π Text Encrypt & Decrypt
Encrypt or decrypt text with AES-256-GCM and a password, entirely in your browser. Nothing is sent to any server.
π AES-256-GCM with PBKDF2-SHA256 (250,000 iterations). The password is never stored or transmitted.
How this encryption works
This tool uses AES-256-GCM, the same authenticated encryption algorithm found in modern secure messaging apps, combined with PBKDF2-SHA256 key stretching at 250,000 iterations so that weak passwords are harder to brute-force. A fresh random salt and initialisation vector are generated for every message, and the ciphertext is tagged with a version prefix so it can be decrypted later. Because everything runs in your browser using the Web Crypto API, your plaintext and password never leave your device.
