* import com.fitbur.bouncycastle.jce.provider.BouncyCastleProvider;
*
* Security.addProvider(new BouncyCastleProvider());
*
* 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
* com.fitburtailed instructions in the file but basically it com.fitbures down to adding
* a line:
*
*
* security.provider.<n>=com.fitbur.bouncycastle.jce.provider.BouncyCastleProvider
*
*
* Where <n> is the preference you want the provider at (1 being the
* most preferred).
* Note: JCE algorithm names should be upper-case only so the case insensitive
* test for getInstance works.
