A simple C++ program written to demonstrate the beauty of the RSA encryption algorithm the internet relies so much on, allowing users to encrypt and decrypt messages as depicted in the images above.

I wanted to demonstrate the functionality of RSA encryption in action. The program assumes the user understands the meaning of the variables involved. Such as n, PHI(n), e and d. Where the user has the power to input any two prime values they want, (p and q values).

The program then allows the user to input a secret message, which then under the hood. Each character will be converted into an ASCII value, then encrypted using c^e mod n. While not the conventional method used in modern encryption software, I find that representing data as what essentially is scrambled ASCII data. Is a lot easier to interpret for a beginner or someone who is unfamiliar with computer jargon, rather than using hexadecimal or other data storing formats.
