You can use the Web Application Management Console to encrypt all settings in the Hyland.Web.AppServerPop element. This is highly recommended. When encrypted, information such as the ChecksumKey value cannot be viewed within the Application Server web.config file.
Encryption is enabled by the Encrypt Configuration setting in the Web Application Management Console. When this setting is applied and saved, information within the Hyland.Web.AppServerPop element is replaced with an EncryptedData element, which contains the encrypted settings.
Saving changes to the server application's web.config file causes the respective web applications to restart. All users connected to the applications will lose their sessions.
For information about using the console to modify and encrypt Pop integration settings, see the Web Application Management Console documentation.
