Data encryption is the process of coding digital data in such a way that it cannot be read if intercepted by a third party. A user must have a special password in order to gain access to encrypted information.

Encryption is used in a variety of internet communication processes, including VoIP conversations. Encryption is especially important for content that is of a sensitive or private matter, such as in the cases of financial transactions and medical prescriptions.
