Public-key encryption: It is a cryptographic system that uses two keys one is the public key and the other is the secret key that is known to the recipient message. There is an element in the public-key and the private keys are related to each other such that public key is used to encrypt messages and the private key can only be used to decrypt them. Traditional encryption: It is a method which takes the original message and a small piece of information arrange in advance between the sender and receiver and creates the encoded version of the message.
