Sorry about that, I incorrectly used a minus sign messing SHA tests up. 
I'm not a coder really. Here is a fixed patch. It also adds some 
dupe-salt checking code that seemed to be missing, in the unlikely case 
there are duplicates.

Now SHA-512 is faster than SHA-256, that was a bit unintuitive to me.
