I have a RSA signature S (128 byte integer )
and modulus n (also 128 byte integer)
I need to calculate
( S**3 ) MOD n
All I need is to perform exponent ( S**3 ) and MOD operation on
128 byte integers.
Is there any large integer class callable from FoxPro which can calculate this ?
I looked also _cypt.vcx foundation class and into Windows Crypto API but
havent found any function which does this.
Any idea ?
