Hi Alex,
I cannot offer you exact numbers, but there were definitely some
significant improvements to the BigInteger.ModPow performance (including
faster MultiplyMonty and less calls to it) after 1.7, so I would expect
it at least worth a try.

Perhaps if you manage to measure an improvement, you could report back
to the list on the results.

Regards,
Pete Dettman
