Well, to be fair, a rolling hash is a hash function, proper. It may well not be what we'd call a cryptographically secure function, and I'll admit I'm not certain of that, that it is my intuition that a rolling hash is not cryptographically secure. I find very little research on cryptographically secure rolling hash functions (for laughs though, search for "secure rolling hash"), but even so, I'm having second thoughts about my statement above.
