public class RC4128Security
extends Security

RC4 128 bit PDF security, with UseCryptFilter property set to false is compatible with PDF version 1.4 or higher and can be read with Adobe Acrobat Reader version 5 or higher. By default UseCryptFilter property is false. RC4 128 bit PDF security with crypt filter is compatible with PDF version 1.5 or higher and can be read with Adobe Acrobat Reader version 6 and higher. Older readers will not be able to read document encrypted with this security. For more details on RC4 128 bit security take a look at the Security topic.
