This setting is used to determine whether or not a checksum will be added to the generated DocPop URL.
If set to true, you must also enter a checksum key value in the ChecksumKey setting, which is used to create the checksum value in the URL. When a user attempts to retrieve a document using a DocPop URL, the value configured in ChecksumKey is compared to the checksum value in the Hyland.Web.DocPop element of the Web Server web.config file. If the values match, the document is displayed. If the values do not match, the user is presented with an error. This is to prevent users from modifying query strings and accessing documents they should not access.
When set to false, no checksum is created.
