What is AES-256?+
AES-256 (Advanced Encryption Standard with 256-bit key) is a symmetric encryption algorithm used worldwide by governments, banks, and security-critical applications. It's considered unbreakable by brute force - testing all possible keys would take longer than the age of the universe.
Is my data safe?+
The tool encrypts and decrypts entirely in your browser using the Web Crypto API. No data, keys, or passwords are ever sent to a server. The security depends entirely on your password strength - use a long, random password.
