#### About Encryption

The purpose of encryption is to modify the data such that it can only be understood by its intended audience. This is accomplished by substituting an encrypted element for the original content. When predicated on public key cryptography, encryption can be used to establish the identity of the parties that can read a message.

When using Encryption, you must have an installed JCE provider that supports encryption. For more information on this topic, read To configure a JCE Provider.
