![]() ![]() This is the easiest way to follow today’s post. More precisely, I recommend SageMath: a software designed for mathematics purposes, which can run over a Jupyter Notebook. However, what I prefer is to use Jupyter Notebook. The code I will show you is written in Python 2.7, so you can use any interpreter to run it. You can always use OpenSSL or similar tools to encrypt and decrypt messages. We want to understand how RSA works, so we are explicitly avoiding pre-implemented libraries. m: message we want to encrypt and send.As a remainder, the real public key is the pair (e, n). This is the modulus we use to calculate the keys. It show the amount of relative primes to n. n: the modulus we use to encrypt and decrypt.p and q: initial random integers (they should be large integers).Here I show the variable we are using and their names: However, they need a lot of variables, so it can become a great headache to remember them all. ![]() The scope is to understand how RSA works in order to use it in a secure way. As I promised, today I bring you a real implementation of the algorithm, using Python. ![]() In the previous post we talked about RSA and how its maths mork. ![]()
