Works with most CI services. the value "e" such that e * d = 1 mod Phi(N) However in this case, 1 mod Phi(N) does not mean The remainder when 1 is divided by Phi(N) (which appears to be the way you have translated it into code, based on your use of math.fmod(1, T), but in fact should be read more like: Ensure that all your new code is fully covered, and see coverage trends emerge. RSA is an asymmetrical encryption algorithm that relies on prime numbers, the larger the prime number the better for cryptography.
