So you're working with RSA?

Here's an RSA source code https://github.com/sjhalayka/RSA

thanks joe but I found what I was looking for. I guess I am not very good at modulus formulas.

My curiosity has not been cured. But at least i have cool avatar pic now :D

‘digit’ implies quite a reduction in the possible input values, now if only we knew the base of the number….

EDIT: Should be less than infinity though, or you wouldn't need more than one digit.

btw I have solved my problem
