Quick Start (MTOM): Encrypting a PDF document using the web service API

The following C# code example encrypts a PDF document named Loan.pdf with a password value of OpenPassword. The master password is PermissionPassword. The secured PDF document is saved as a PDF file named EncryptLoan.pdf. (See Encrypting PDF Documents with a Password.)

    * 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
