Acrobat standard security (40-bit and 128-bit RC4 encryption) includes password protection and setting change and display permissions, such as printing and content extraction, for a PDF file.
 | Useful Information
As of ICEpdf 6.1 the Bouncy Castle jars are now needed for ICEpdf to support PDF Digital Signatures. The Bouncy Castle jars are included in the bundles ./lib folder. Prior to version 6.1 the Bouncy Castle jars are not needed. |
If you use a different JCE 1.2.1-compliant security provider, you must set the system property org.icepdf.core.security.jceProvider appropriately. See System Properties for details.
 | Warning
You must also code your application to respect the security settings. For example, you must disable printing if a PDF file is set with "No Printing" permissions. The ICEpdf Viewer reference implementation has been coded to respect security permissions, and you can use its source code as a model for your own application. |
