Add exponent blinding to RSA without CRT

The sliding window exponentiation algorithm is vulnerable to
side-channel attacks. As a countermeasure we add exponent blinding in
order to prevent combining the results of fifferent measurements.

This commits handles the case when the Chinese Remainder Theorem is NOT
used to accelerate computations.
