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-bit (32 hex digit) key. 128-bit key is most often used in dongles.


Example AES test values (taken from FIPS-197) are:

Key: 000102030405060708090a0b0c0d0e0f
Plaintext: 00112233445566778899aabbccddeeff
Ciphertext: 69c4e0d86a7b0430d8cdb78070b4c55a

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