http://www.bouncycastle.org/java.html: The Bouncy Castle Crypto package is a Java implementation of cryptographic algorithms. This jar contains JCE provider and lightweight API for the Bouncy Castle Cryptography APIs for JDK 1.5 to JDK 1.7.

import org.bouncycastle.jce.interfaces.ConfigurableProvider;


To add the provider at runtime use:

import java.security.Security;
import org.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
detailed instructions in the file but basically it comes down to adding
a line:


   security.provider.<n>=org.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.
