Due to export control restrictions, by default the 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.


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