AES cipher internals in Excel

Here you can encrypt a block of bytes with a key using the popular Advanced Encryption Standard cipher. All the internal steps of the computation are shown, which can be helpful for anyone debugging their own AES implementation. In each of the 10/12/14 rounds, the sub-steps of SubBytes, ShiftRows, MixColumns, AddRoundKey, and key schedule are shown. Keep in mind that AES data squares are serialize
