Detailed explanation-1: -Public key encryption is also referred to as asymmetric encryption because there is not just one key used in both directions as with the symmetric encryption. In public key encryption there are two keys; whichever one is used to encrypt requires the other be used to decrypt.
Detailed explanation-2: -Asymmetric encryption (also known as asymmetric cryptography) allows users to encrypt information using shared keys. You need to send a message across the internet, but you don’t want anyone but the intended recipient to see what you’ve written.
Detailed explanation-3: -The correct response is true. Asymmetric keys use two separate keys, one key to encrypt and one key to decrypt information. These are known as public and private key pairs.
