Please could you just help me, as im new adherent in this site, i dont have enough knowledges about these command.

Many thank in advance

This code uses the GMP (Gnu Multi Precision) Library which operates with big integers in order to calculate the two needed constants to perform a fast modular exponentiation.

If you want to know where do this constants comes from, you can google for the CIOS Montgomery modular multiplication.

But you don't need to know all this to use the core.

Once you have your m value, change the .c one with yours and execute, then you obtain your constants and you use them as inputs for the core.
