Public key encryption method uses a pair of keys, one public key available to anyone and one private key known only to the recipient. The public key is used to encrypt the message and the private key is used to decrypt it. Symmetric key encryption uses a single shared secret key for both encryption and decryption, and shared key encryption is another name for symmetric key encryption. Universal key does not exist as a standard encryption method.
