He may change what I have given him, but it 'shows' what was going on. I gave him 3 options. I am not sure which is the 'best'. I also gave him a test vector that would have failed. Failing: Any password where len(pw)%4 === 1 or 2 if len(pw)%4==0 or 3, it would load the ipad/opad properly and work. There were no self test that hit that congruent 1 or 2 length.
