Answer: A - Asymmetric cryptography ensures that both authentication and encryption can happen without sharing private keys.

Asymmetric cryptography, or public-key cryptography, is cryptography in which a pair of keys is used to encrypt and decrypt a message so that it arrives securely. These asymmetric keys are referred to as the public key and the private key. It uses one key per circuit. The public key is used to encrypt the message and the private key is used to decrypt it.
