Here are results of test runs with all the sample test data supplied in the AES Specification and in B. Gladman's writeup about the AES. The values in the state variable are shown at the start of each round. There are also test runs with plaintext and key all zeros and with a single 1 inserted. The AES Specification and Gladman also show step-by-step results of the key expansion for these cases, which was useful for my debugging, but I don't show that data here.
