# Encrypt the View Server Cache

When the View component converts a document to HTML, it caches the results. If it receives a request for the same document again, it retrieves the version from the cache, rather than converting it again. You can configure View to encrypt the cache.

To enable encryption in the configuration file

IMPORTANT: If you have installed a unified setup, the same configuration file is used by the Content and View components, so editing this file will also enable encryption for the Content data index. OpenText recommends that you read Encrypt the Data Index before making any changes.

1. Stop the View component.
2. Open the View configuration file.
3. Find the `[DataEncryption]` section, or create the section if it does not exist.

4. Set the parameter AESKeyFile to the path of the AES key file. For example:

       [DataEncryption]
       AESKeyFile=C:\KnowledgeDiscovery\keys\key.ky

   TIP: Create a key file using the `autpassword` utility (see Encrypt Passwords).

5. Save and close the configuration file.
6. Start the View component.

To enable encryption when starting the server

- When you start the View component, you can use the `-dataencryptionkey` argument to enable encryption. Set this option to the 64-character hexadecimal AES key that you want to use. For example:

      view.exe -configfile view.cfg -dataencryptionkey <key>

  Setting this argument overrides any key file set in the configuration file.
