modInverse support #6

Closed wilko77 closed 8 years ago

wilko77 commented 8 years ago

We are using your library for implementing homomorphic encryption schemes. During benchmarking I realised that the 'modInverse' implementation of BigInteger is an order of magnitude slower than the GMP one. Therefore I extended your code to also offer access to the GMP implementation for computing a modular inverse. I believe this modifications could be useful to others trying to improve the runtime of their Java crypto implementations.

Thanks so much for the patch. Looks mostly good at a glance, I'll load it up and run the tests.
