Class PDFEncryptionManager

java.lang.Object
  extended by org.apache.fop.pdf.PDFEncryptionManager

public final class PDFEncryptionManager
extends java.lang.Object

This class acts as a factory for PDF encryption support. It enables the feature to be optional to FOP depending on the availability of JCE.


Method Summary
static boolean checkAvailableAlgorithms()
          Checks whether the necessary algorithms are available.
static boolean isJCEAvailable()
          Indicates whether JCE is available.
static PDFEncryption newInstance(PDFEncryptionParams params, PDFDocument pdf)
          Creates a new PDFEncryption instance if PDF encryption is available.
static void setupPDFEncryption(PDFEncryptionParams params, PDFDocument pdf)
          Sets up PDF encryption if PDF encryption is requested by registering a PDFEncryptionParams object with the user agent and if the necessary cryptographic support is available.

Method Detail

isJCEAvailable

public static boolean isJCEAvailable()
Indicates whether JCE is available.

Returns:
boolean true if JCE is present

checkAvailableAlgorithms
