Does anyone know how I can get the square root of a BigInteger? I tried this:

It didn't like that. It said that Math.pow cannot be applied to doubles!
Any help would be appreciated, sorry for asking so many questions!

I was just about to post the same link, but Ernest beat me to it.

Incidentally, since you're working with cryptography, you might be interested in the nextProbablePrime() method in BigInteger. This is new with Java 1.5.
