Unlimited JCE (Obsolete)

This article is Obsolete.

As of version 3.0.0 DidiSoft OpenPGP Library for Java no longer requires the Unlimited JCE files!

Due to export control restrictions, by default the Java Development Kit (JDK) is supplied with limited cipher key lengths.

In order to enable full cipher key length additionally should be downloaded:
Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files

In both cases you have to download a ZIP file and copy the content of the ZIP in your JRE’s jre/lib/security/ folder.

When you develop your application in an IDE like Eclipse or NetBeans they use the JRE located at the JDK/jre folder. When your application is executed either from the command line or in an application folder then they usually use the separate JRE folder.

Note: This operation has to be done for every machine where this library will be distributed.

Bellow you will find links from where you can download them for Oracle (previously Sun) and IBM Java Virtual Machine (JVM) version 1.7 (Java 7), 1.6 (Java 6), 1.5 (Java 5) and 1.4.
