Asymmetric cryptography has separate keys for encrypting and decrypting. These keys are known as the public and private keys, respectively.

Purpose

Since the key protects the confidentiality and integrity of the system, it is important to be kept secret from unauthorized parties. With public key cryptography, only the private key must be kept secret, but with symmetric cryptography, it is important to maintain the confidentiality of the key. Kerckhoff's principle
