What is AES encryption?

AES (Advanced Encryption Standard) is a symmetric encryption algorithm adopted by the U.S. government and used worldwide. It encrypts data in fixed-size blocks using a secret key, making it virtually impossible to decrypt without the correct key.

What is AES-GCM mode?

GCM (Galois/Counter Mode) is an authenticated encryption mode that provides both confidentiality and data integrity. It ensures your data cannot be tampered with during transmission and detects any modifications.

PBKDF2 (Password-Based Key Derivation Function 2) converts your password into a cryptographic key using 100,000 iterations. This makes brute-force attacks extremely slow and impractical.

Yes. All encryption happens locally in your browser using the Web Crypto API. Your data and password never leave your device or get sent to any server.

What key size should I use?

AES-256 is recommended for maximum security. AES-128 is also secure and slightly faster. All three options (128, 192, 256) are considered secure for current use.
