Correction, I just noticed that the four F functions have 4 bit output not 8 as I wrote. Realize that all this is based on a very cursory examination of the code. BTW I just was starting to look at the key scheduling and I noticed that fullkey is indexed in its 2nd slot by i*2 where i goes from 0 to 31, but is only declared as being 32 in size in that slot. So I think this is another typo, probably the index should be i. This kind of thing does not inspire confidence... Hal
