Explanation:
Detailed explanation-1: -Symmetric encryption uses a private key to encrypt and decrypt an encrypted email. Asymmetric encryption uses the public key of the recipient to encrypt the message. Then, if the recipient wants to decrypt the message, the recipient will have to use their private key to decrypt.
Detailed explanation-2: -Asymmetric encryption is also called public key encryption, but it actually relies on a key pair. Two mathematically related keys, one called the public key and another called the private key, are generated to be used together. The private key is never shared; it is kept secret and is used only by its owner.
