Class SystemSecurityHandlerV4
java.lang.Object
de.intarsys.pdf.crypt.SystemSecurityHandler
de.intarsys.pdf.crypt.SystemSecurityHandlerV4
- All Implemented Interfaces:
- ISystemSecurityHandler
public class SystemSecurityHandlerV4
- extends SystemSecurityHandler
The ISystemSecurityHandler
implementing /V 4 of the PDF spec.
The crypt handlers are created lazy and never changed - it is unwise to
change any encryption parameters afterwards!
