Symmetric encryption can protect the confidentiality of an e-mail message by ensuring that no one has read it. This method uses a single key to encrypt and decrypt the message, ensuring that only the intended recipient with the corresponding key can read the message. Other forms of encryption, such as public and asymmetric encryption, can also provide confidentiality, but symmetric encryption is the most common method used for e-mail communication.
