One possibility is that the author may have simply decompiled the original code...

This might explain the char % 255's in the code. Normally such a ... may surprise some of us that some machines can do a MOD faster than an AND and the compiler used might have exploited that feature.

It wouldn't explain the construct Hal pointed out, though:

xorIndex = state[x] + (state[y]) % 256;

Here it's either a bug or a no-op, so a decompiler wouldn't have produced it. Jim Gillogly 26 Halimath S.R. 1994, 16:43
