What do you mean with "calculate"?

That number, if expressed in decimal has 3.9×10^99 digits.
The universe is not big enough to contain all these digits.  8-)

Why do you think you need to calculate this number to implement ssh
(I don't know the details of ssh)?  Note that if you need to calculate
2^BigNumber mod ReasonableNumber, then there's no need to
calculate 2^BigNumber.
