Quick Start: Encrypting a PDF document using the Java API

The following Java 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.)

/*

 * This Java Quick Start uses the following JAR files

 * 1. adobe-encryption-client.jar

 * 2. adobe-livecycle-client.jar

 * 3. adobe-usermanager-client.jar

 * 4. adobe-utilities.jar

 * 5. jbossall-client.jar (use a different JAR file if LiveCycle ES is not deployed

 * on JBoss)

 * 

 *  These JAR files are located in the following path:

 * <install directory>/Adobe/LiveCycle8/LiveCycle_ES_SDK/client-libs

 * 

 * For complete details about the location of these JAR files, 

 * see "Including LiveCycle ES library files" in Programming 

 * with LiveCycle ES
