Public key encryption: Public key encryption is a cryptographic system that uses two keys which is the public and the private key. A public key is known to everyone whereas private or secret key is known only to the recipient of the message. In public key encryption, the public key can be used to encrypt messages and only the corresponding private key can be used to decrypt them. Private key encryption: Private key encryption is a form of encryption where only a single private key can encrypt and decrypt information. Since it uses a single key, it is a fast process. When everyone is using private keys, protecting one key creates a key management issue.
