The distinguishing feature of asymmetric encryption is that it uses distinct keys for encryption and decryption3. Asymmetric encryption, also known as public-key encryption, involves two keys: a public key that can be shared with anyone and used to encrypt messages; and a private key that is kept secret by its owner and used to decrypt messages 3. The other options are not features of asymmetric encryption.
