Encrypt and decrypt text using AES-GCM with a password
Enter text and password to encrypt or decrypt
Encryption Tool is a free online tool that lets you encrypt and decrypt text using AES-256-GCM, one of the most secure symmetric encryption algorithms available. Simply enter your text and a password to produce an encrypted ciphertext that can only be decrypted with the same password. The tool uses the Web Crypto API built into modern browsers, deriving a 256-bit encryption key from your password using PBKDF2 with a random salt. Each encryption produces unique output even with the same text and password, thanks to random initialization vectors. All processing happens entirely in your browser — no data or passwords are ever transmitted to any server.
