8 | ** -- G modified to have y&~z instead of y&z ** |
---|
9 | ** -- FF, GG, HH modified to add in last register done ** |
---|
10 | ** -- Access pattern: round 2 works mod 5, round 3 works mod 3 ** |
---|
11 | ** -- distinct additive constant for each step ** |
---|
12 | ** -- round 4 added, working mod 7 ** |
