Adding Usage Rights to a Document

You may decide which usage rights will be permitted for a set of users. You may specify

either full, unrestricted access to the document, or rights that address accessibility, content

extraction, allowing changes, and printing. You may use Acrobat JavaScript to customize

these rights when encrypting a document for a list of recipients. For more information, see

Encrypting PDF Files for a List of Recipients

As you have seen throughout this chapter, the

encryptForRecipients

method is the primary means of encrypting PDF files for a list of recipients using Acrobat

JavaScript. In the previous example, the certificates used were gathered by connecting to a

, which is a repository of user information. The

property with which it is possible to create and activate a new directory, and is

accessible either through the

DirectoryInformation

object, which may contain standard

properties related to the name of the directory, as well as additional properties specific to a

particular directory handler (these may include server and port information).

To create a new directory, create a

DirectoryInformation

object and invoke its

method, and assign the

DirectoryInformation

object to the new directory’s

property. An example of

this is given below:

// Create and activate a new directory:

dirStdEntryID: "dir0",

dirStdEntryName: "Employee LDAP Directory",

dirStdEntryPrefDirHandlerID: "Adobe.PPKMS.ADSI",

dirStdEntryDirType: "LDAP",

server: "ldap0.acme.com",

// Obtain the security handler:

var sh = security.getHandler("Adobe.PPKMS");

// Create the new directory object:

var newDir = sh.newDirectory();

// Store the directory information in the new directory:

newDir.info = newDirInfo;
