WebSecret key cryptography, also known as symmetric encryption, uses a single key to encrypt and decrypt a message. The sender encrypts the plaintext message using the key and sends it to the recipient who then uses the same key to decrypt it and unlock the original plaintext message. Stream Ciphers WebSecret Key In symmetric cryptography a secret key (or “private key”) is a piece of information or a framework that is used to decrypt and encrypt messages. Each party to a conversation that is intended to be private possesses a common secret key.

WebPublic 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.
