# Transform the hypothetical round key into the actual value of the 13th round key.
# Reverse the 13th and 14th round keys using the AES-256 key schedule to determine the 256 bit secret encryption key.
 == Attacking Round Key 14 ==== Attacking Round Key 13 ==== Recovering the Full Key ==Once this is done, we have successfully attacked an AES-256 implementation by looking at two separate AES S-boxes.
