Quick Start (MTOM): Assembling an encrypted PDF document using the web service API

The following C# code example assembles a password-encrypted PDF document. The unsecured PDF document is named Loan.pdf. Notice that the name of the DDX document is shell_Encrypt.xml. The encrypted PDF document is named AssemblerEncryptedPDF.pdf. The encrypted PDF document is named AssemblerEncryptedPDF.pdf. (See Assembling Encrypted PDF Documents.)

    * Ensure that you create a .NET project that uses  
    * MS Visual Studio 2008 and version 3.5 of the .NET 
    * framework. This is required to invoke a  
    * LiveCycle service using MTOM. 
    * For information, see "Invoking LiveCycle using MTOM" in Programming with LiveCycle  
    * * The following XML represents the DDX document used in this quick start: 
    *<?xml version="1.0" encoding="UTF-8"?> 
    *  <DDX xmlns="http://ns.adobe.com/DDX/1.0/"> 
    *   <PDF result="EncryptLoan.pdf" encryption="userProtect"> 
    *        <PDF source="inDoc" /> 
    *    </PDF> 
    *    <PasswordEncryptionProfile name="userProtect" compatibilityLevel="Acrobat7"> 
    *        <OpenPassword>AdobeOpen</OpenPassword> 
    *   </PasswordEncryptionProfile> 
    * </DDX>
