Explanation:

Digital encryption is the process of transforming data into an unreadable form using a secret key or algorithm. Digital encryption will ensure the confidentiality of content when accessing an email system over the Internet, as it prevents unauthorized parties from intercepting, viewing, or modifying the email messages. Digital encryption can be applied to both the email content and the email transmission, using different methods such as symmetric encryption, asymmetric encryption, or hybrid encryption. Digital encryption can also provide other benefits such as authentication, integrity, and non-repudiation, depending on the encryption scheme and the use of digital signatures or certificates.Reference= CISM Review Manual 15th Edition, page 101, page 102.
