+Installing the Java Cryptography Extension Unlimited Strength policy files is necessary to do testing
+with quite a lot of practical key sizes, they are available for download:

+ * [Java 6](http://www.oracle.com/technetwork/java/javase/downloads/jce-6-download-429243.html)
+ * [Java 7](http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html)
+ * [Java 8](http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html)
