Encryption and decryption using RSA

RSA uses the following equation to produce ciphertext:

C = Pe mod n

This means that plaintext P is raised to e number of times and then reduced to modulo n. Decryption in RSA is provided in the following equation:

P = Cd mod n

This means that the receiver who has a public key pair (n, e) can decipher the data by raising C to the value of the private key d and reducing to modulo n.
