Detailed explanation-1: -An encryption key is typically a random string of bits generated specifically to scramble and unscramble data.
Detailed explanation-2: -Ciphertext: This is the scrambled (unintelligible) message produced as output. It depends on the plaintext and the secret key.
Detailed explanation-3: -The process of using cryptography to scramble a message is called encryption. The process of unscrambling the message by use of the appropriate key is called decryption.
Detailed explanation-4: -Public key cryptography is a method of encrypting or signing data with two different keys and making one of the keys, the public key, available for anyone to use. The other key is known as the private key. Data encrypted with the public key can only be decrypted with the private key.
