i can't help you with the cryptography stuff, but in cases like your
example, i think reduce() might be useful, but your *specific* case
can be handled with a 1-liner:
>>> sum([x for x in range(100) if x % 2])
2500
or the same using less memory in Python 2.4+:
>>> sum(x for x in range(100) if x % 2)
2500
hope this helps!
