Which of the following is true about digitally signed e-mails?

Digitally signed emails provide enhanced security by ensuring the authenticity and integrity of the message. When an email is digitally signed, it utilizes a cryptographic technique that allows the recipient to verify that the sender is indeed who they claim to be, and that the content of the email has not been altered during transmission.

The digital signature is created using a private key, which only the sender possesses, while the recipient can use the corresponding public key to confirm the signature. This means that any tampering with the email after it has been signed would result in the signature not matching, thus alerting the recipient to a potential security issue.

By strengthening the verification process and protecting against impersonation and message alteration, digitally signed emails enhance the overall security of email communications, making them more secure than unsigned emails. This capability is critical in both personal and professional communications, especially within organizations that place a high priority on data security.
