AES Calculator

You can use the AES Calculator applet displayed below to encrypt or decrypt

using AES the specified 128-bit (32 hex digit) data value with the
128/192/256-bit (32/48/64 hex digit) key, with a trace of the calculations.
Some example values which may be used are given below.

Example AES test values (taken from FIPS-197) are:
Key: 000102030405060708090a0b0c0d0e0f
Plaintext: 00112233445566778899aabbccddeeff
Ciphertext: 69c4e0d86a7b0430d8cdb78070b4c55a

Key: 000102030405060708090a0b0c0d0e0f1011121314151617
Plaintext: 00112233445566778899aabbccddeeff
Ciphertext: dda97ca4864cdfe06eaf70a0ec0d7191

Key: 000102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f
Plaintext: 00112233445566778899aabbccddeeff
Ciphertext: 8ea2b7ca516745bfeafc49904b496089

Encrypting the plaintext with the key should give the ciphertext,
decrypting the ciphertext with the key should give the plaintext.
