AES Encryption

Encrypt or decrypt text with a password using AES-256-GCM and PBKDF2 key-stretching — all through the browser’s native Web Crypto. The password is never stored or sent; everything happens on your device.

How it works

Text is encrypted with AES-GCM (256-bit) using the browser’s native Web Crypto. Your password is stretched into a key with PBKDF2 (SHA-256, 150,000 iterations) over a random salt, and a fresh random IV is used each time — so encrypting the same text twice gives different output, as it should. The salt and IV are packed with the ciphertext into one Base64 blob. Everything happens on your device; the password is never stored or sent. Lose the password and the text is unrecoverable.
