AES-128/192/256 algorithm for creating a cipher given a 128-bit hexadecimal input message and 128/192/256-bit hexadecimal key. Created using FIBS-197 standard. Algorithm was not built for speed and does not covert a text message or data input 128-bit input blocks. Cipher and InvCipher are the main functions to execute. Function executes AES128 or AES192 or AES256 based on the key size. Functions do not check whether the key size or input are the correct length and will error if they are not the correct size.

Example:
Out = Cipher(key,In)
%key='000102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f'
%In='00112233445566778899aabbccddeeff'
%Out='8ea2b7ca516745bfeafc49904b496089'

Out=InvCipher(key,In)
%key='000102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f'
%In='8ea2b7ca516745bfeafc49904b496089'
%Out='00112233445566778899aabbccddeeff'
