This project is a program developed to encrypt/decrypt a string using the algorithm RSA. Of course, it uses small prime numbers in order to compute a simple string, but it can be used for larger primes too.
Simply download the repo, make sure you have python 3 installed on your system, and execute the command you want to use:
python app.py --encrypt="Hello world"
python app.py --decrypt=HUll@zw@Ml8
