Foxit Configuration Tool (Used in a Windows AIP Server)

Foxit PDF Editor AIP Protect feature provides a handy configuration tool for administrators to better modify the protection settings on an AIP server. Administrators can directly enable/disable each tool, edit the extended policies of official templates, dynamically revoke permissions, audit logs, and customize wrapper files.

To use the configuration tool to encrypt PDFs, please do the following:

• Log in to your AIP server.
• Download the Foxit Configuration Tool from:
  • Foxit Configuration Tool (for X86)
  • Foxit Configuration Tool (for X64)
• Unzip and Run Foxit Configuration Tool, you can then use the different tools in the Foxit Configuration Tool window. Note: Before getting started, you need to configure the VBScript in the unzipped folder by inputting your specific localhost address and port number in the script. The default port number in the script is 80, such as admin_role = config_manager.Initialize(true,"localhost",80,"","",""). You need to change the port number to the one your server currently uses.

Template Extended Policy

With the Foxit Configuration Tool, administrators can easily edit the extended policy of official templates. Click Template ExtendedPolicy tool and choose one template to edit. See also Extended Policy.

Tip: Click the Back button in the left corner to return to the Foxit Configuration Tool window.

Dynamic Revocation

Revocation is a mechanism that revokes a PDF document that has already been issued. A common use of revocation is to remove rights from an individual when he is no longer authorized or to restrict access to a document when it becomes out of date or invalid.

Note: To revoke a PDF document/user in an on-premise environment, please refer to Web Service Configuration to configure the web service and SQL first. Then choose the Revocation tool in the Foxit Configuration Tool window and enable the tool by clicking the button .

To revoke a PDF document, click Document Revocation. Select the PDF document you want to revoke, click the Add button to add the document to the Revocation List. Or you can click Browse to select a document from a local drive to add to the Revocation List. To remove the revocation, please select the document in the Revocation List and click the Remove button.

To revoke a user, click User Revocation. Click Add button to add a user to the User Revocation List. To remove the revocation, please select the user in the list and click Remove button.

Extended Policy

Foxit Configuration Tool provides you with Extended Policy to add complete PDF protection and control to your PDF documents. The policy allows documents owners to control the number of access and the number of prints in an on-premise environment. Before you specify the two permissions, please refer to Web Service Configuration to configure the web service and SQL first, and then choose the Extended Policy tool in the Foxit Configuration Tool window and enable the tool by clicking the button .

Auditing Logs

Foxit PDF Editor enables you to track the usage of AIP protected files to record the actions on the files during workflow, including who accessed the document, what document was accessed, when it was accessed, how it was accessed and the success of that access, and more.

To audit logs, please refer to Web Service Configuration to configure the web service and SQL first, and then choose the Audit Log tool in the Foxit Configuration Tool window and enable the tool by clicking the button .

Choose one log and click on the Export button to export to Foxit PDF Reader's registry or Foxit PDF Editor's to generate a .reg file for the administrator's configuration. The administrator can distribute the .reg file to client-end computers.

Edit Wrapper Content

If you open a PDF which is encrypted by Foxit with other PDF viewers, a wrapper (which is a PDF page) appears with a prompt that you need to download Foxit PDF Reader/Foxit PDF Editor to open the encrypted PDF. With Foxit Configuration Tool, you can customize the wrapper by selecting a desired PDF file.

To apply a custom wrapper, please refer to Web Service Configuration to configure the web service and SQL first. Then choose the Edit Wrapper Content tool in the Foxit Configuration Tool window, enable the tool by clicking the button , and select a desired PDF file.
