RSA:

This Python file contains a simple implementation of the RSA encryption and decryption algorithm.

Encryption:

The encryption formula used is:

where m is the plaintext message, e is a randomly generated co-prime integer to n, and n is the product of two large prime numbers, p and q.

Decryption:

The decryption formula used is:

where c is the encrypted message, d is the private key generated using p and q and e, and n is the product of the same two prime numbers used for encryption.
