AES Encrypt

Encrypt and decrypt text with AES-GCM or AES-CBC using a passphrase or hex key, entirely in your browser.

Passphrase

Passphrases are stretched with PBKDF2-SHA256 (100,000 iterations) and a random salt stored in the output JSON.

Encrypts UTF-8 text and returns a portable JSON payload with IV and ciphertext.
