     * To add the provider at runtime use:
     * <pre>
     * import java.security.Security;
     * import com.trustpoint.m2m.M2MProvider;
     *
     * Security.addProvider(new M2MProvider());
     * </pre>
     * The provider can also be configured as part of your environment via static registration by
     * adding an entry to the java.security properties file (found in
     * $JAVA_HOME/jre/lib/security/java.security, where $JAVA_HOME is the location of your JDK/JRE
     * distribution). You'll find detailed instructions in the file but basically it comes down to
     * adding a line:
     * <pre>
     * <code>
     *    security.provider.&lt;n&gt;=com.trustpoint.m2m.M2MProvider
     * </code>
     * </pre>
     * Where &lt;n&gt; is the preference you want the provider at (1 being the most preferred).
     * <p>Note: JCE algorithm names should be upper-case only so the case insensitive test for
     * getInstance() works.
