/**
 * Example provider that demonstrates some of the new API features. . implement multiple different
 * algorithms in a single class. Previously each algorithm needed to be implemented in a separate
 * class (e.g. one for MD5, one for SHA-1, etc.) . multiple concurrent instances of the provider
 * frontend class each associated with a different backend. . it uses "unextractable" keys and lets
 * the framework know which key objects it can and cannot support
 * 
 * Note that this is only a simple example provider designed to demonstrate several of the new
 * features. It is not explicitly designed for efficiency.
