Public Key and Asymmetric - Public-key cryptography uses a pair of keys, one that is designated the private key and kept secret, the other key is called the public key and is generally made available. Information encrypted using one key can only be decrypted using the other, and vice versa. The implication of this is that if a message can be decrypted using the public key, then it must have been sent from the owner of the private key.
