So wait, all you want to do is algebra in the ring Z_{2^32}?

Assuming this is right, why not just make a RingElement class that has
all the operators overloaded to perform the appropriate operation and
then perform the appropriate modulus. With appropriate optimizations if
needs be.

Sorry, I came in on the end of this, but perhaps this will be helpful.

James.
