🔐 About AES Encryption

🛡️

What is AES?

Advanced Encryption Standard (AES) is a symmetric encryption algorithm adopted by the U.S. government. It's considered secure and is widely used worldwide for protecting sensitive data.

🔑

Key Sizes

AES supports three key sizes: 128-bit (fast), 192-bit (balanced), and 256-bit (maximum security). Higher key sizes provide stronger security but may be slightly slower.

🔄

Encryption Modes

CBC: Cipher Block Chaining (recommended)

ECB: Electronic Codebook (less secure)

GCM: Galois/Counter Mode (authenticated)

📦

Padding Schemes

PKCS#7: Standard padding (recommended)

ANSI X9.23: Zero bytes + length byte

ISO 10126: Random bytes + length byte

Zero Padding: Pad with zero bytes
