Deriving a random long value from random integers

I have a method int randInt(int min, int max) that generates a random integer between min and max inclusive. It interfaces with an external system that has a good source of entropy.

The external system only generates 32-bit integers, while I need to get a 64-bit long.

Is it possible to compose several random integers to create a long without introducing any new bias?

@seldary But that doesn't take into account min and max. – ICR Sep 30 '11 at 13:54
