Class PDFEncryptionManager


public 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.

Field Summary

protected static Log
log
logging instance

Method Summary

static boolean
checkAvailableAlgorithms()
Checks whether the necessary algorithms are available.
static boolean
isJCEAvailable()
Indicates whether JCE is available.
static PDFEncryption
newInstance(int objnum, PDFEncryptionParams params)
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.
