What is AES-256? Advanced Encryption Standard (AES) with 256-bit keys is a symmetric encryption algorithm used worldwide for securing sensitive data. It's the same encryption standard used by governments and banks.
How it Works: Your text is encrypted using your password as the key. The encrypted output is Base64-encoded for easy sharing. To decrypt, paste the encrypted text and enter the same password.
Security Tips: Use a strong, unique password. Never share your password with the encrypted text. Remember your password - there's no recovery option. For maximum security, use passwords with 16+ characters.
Privacy: All encryption and decryption happens in your browser. No data is sent to any server. Your text and password never leave your device.
Use Cases: Secure messaging, password storage notes, sensitive document protection, confidential data sharing, private journal entries, API key storage.
