Removing Policies from PDF Documents

To remove a policy from a policy-protected PDF document, perform the following steps:

1. Include project files

2. Create a Rights Management Client API object.

3. Retrieve a policy-protected PDF document.

4. Remove the policy from the PDF document.

5. Save the unsecured PDF document.

Remove a policy from a policy-protected PDF document by using the Rights Management API (Java):

1. Include project files.

   Include client JAR files, such as adobe-rightsmanagement-client.jar, in your Java project’s class path.

2. Create a Rights Management Client API object.

   • Create a ServiceClientFactory object that contains connection properties.

   • Create a RightsManagementClient object by using its constructor and passing the ServiceClientFactory object.

3. Retrieve a policy-protected PDF document.

   • Create a java.io.FileInputStream object that represents the policy-protected PDF document by using its constructor and passing a string value that specifies the location of the PDF document.

   • Create a com.adobe.idp.Document object by using its constructor and passing the java.io.FileInputStream object.

4. Remove the policy from the PDF document.

   • Create a DocumentManager object by invoking the RightsManagementClient object’s getDocumentManager method.

   • Remove a policy from the PDF document by invoking the DocumentManager object’s removeSecurity method and passing the com.adobe.idp.Document object that contains the policy-protected PDF document. This method returns a com.adobe.idp.Document object that contains an unsecured PDF document.

5. Save the unsecured PDF document.

   • Create a java.io.File object and ensure that the file extension is PDF.

   • Invoke the Document object’s copyToFile method to copy the contents of the Document object to the file (ensure that you use the Document object that was returned by the removeSecurity method).

Remove a policy from a policy-protected PDF document using the Rights Management API (web service):

1. Include project files.

   Create a Microsoft .NET project that uses MTOM. Ensure that you use the following WSDL definition: http://localhost:8080/soap/services/RightsManagementService?WSDL&lc_version=9.0.1 .

   Note: Replace localhost with the IP address of the server hosting LiveCycle.

2. Create a Rights Management Client API object.

   • Create a RightsManagementServiceClient object by using its default constructor.

   • Create a RightsManagementServiceClient.Endpoint.Address object by using the System.ServiceModel.EndpointAddress constructor. Pass a string value that specifies the WSDL to the LiveCycle service (for example, http://localhost:8080/soap/services/RightsManagementService?WSDL .) You do not need to use the lc_version attribute. This attribute is used when you create a service reference.)

   • Create a System.ServiceModel.BasicHttpBinding object by getting the value of the RightsManagementServiceClient.Endpoint.Binding field. Cast the return value to BasicHttpBinding .

   • Set the System.ServiceModel.BasicHttpBinding object’s MessageEncoding field to WSMessageEncoding.Mtom . This value ensures that MTOM is used.

   • Enable basic HTTP authentication by performing the following tasks:

     • Assign the AEM forms user name to the field RightsManagementServiceClient.ClientCredentials.UserName.UserName .

     • Assign the corresponding password value to the field RightsManagementServiceClient.ClientCredentials.UserName.Password .

     • Assign the constant value HttpClientCredentialType.Basic to the field BasicHttpBindingSecurity.Transport.ClientCredentialType .

   • Assign the constant value BasicHttpSecurityMode.TransportCredentialOnly to the field BasicHttpBindingSecurity.Security.Mode .

3. Retrieve a policy-protected PDF document.

   • Create a BLOB object by using its constructor. The BLOB object is used to store the policy-protected PDF document from which the policy is removed.

   • Create a System.IO.FileStream object by invoking its constructor and passing a string value that represents the file location of the PDF document and the mode in which to open the file.

   • Create a byte array that stores the content of the System.IO.FileStream object. You can determine the size of the byte array by getting the System.IO.FileStream object’s Length property.

   • Populate the byte array with stream data by invoking the System.IO.FileStream object’s Read method and passing the byte array, the starting position, and the stream length to read.

   • Populate the BLOB object by assigning its MTOM field with the contents of the byte array.

4. Remove the policy from the PDF document.

   Remove the policy from the PDF document by invoking the RightsManagementServiceClient object’s removePolicySecurity method and passing the BLOB object that contains the policy-protected PDF document. This method returns a BLOB object that contains an unsecured PDF document.

5. Save the unsecured PDF document.

   • Create a System.IO.FileStream object by invoking its constructor and passing a string value that represents the file location of the unsecured PDF document.

   • Create a byte array that stores the data content of the BLOB object that was returned by the removePolicySecurity method. Populate the byte array by getting the value of the BLOB object’s MTOM field.

   • Create a System.IO.BinaryWriter object by invoking its constructor and passing the System.IO.FileStream object.
