18  * \brief          Perform a modular exponentiation: X = A^E mod N
20  * \warning        This function is not constant time with respect to \p E (the exponent).
23  *                 This must not alias E or N.
26  * \param E        The exponent MPI. This must point to an initialized MPI.

42  *                 even, or if \c E is negative.
