🔐 AES: The Advanced Encryption Standard

Explore how AES, the symmetric block cipher trusted by governments and banks worldwide, encrypts data in 128-bit blocks through rounds of substitution, shifting, mixing, and key XORing.

This simulator visually walks through how a 128-bit block of data is transformed by AES, showing the state matrix change as SubBytes, ShiftRows, MixColumns, and AddRoundKey are applied across multiple rounds.

🔬 What It Demonstrates

🎮 How to Use

Enter or generate a sample block and key, then step forward through each round and operation to watch the state matrix evolve from plaintext into ciphertext.

💡 Did You Know?

Despite being one of the most heavily analyzed ciphers in the world, no practical attack has ever broken full-round AES, which is why it remains the encryption backbone of banking, government, and internet security systems today.
