[issue34751] Hash collisions for tuples

Being crypto-strength and having few collisions statistically are different properties.

For non-crypto hash functions it's typically very easy to generate collisions once you know the parameters (which are called the "key" for crypto hash functions). But I think that you shouldn't be able to produce a large number of collisions if you don't know the parameters in advance.
