BouncyCastleProvider class not found in Grails 2.5.0

Question

I have a Grails project in which I want to use Bouncycastle to calculate a Sha512 hash of a string.

When I call Security.addProvider(new BouncyCastleProvider()) I get the following error message:

| Error 2015-06-21 15:34:53,242 [localhost-startStop-1] ERROR context.GrailsContextLoaderListener  - Error initializing the application: org/bouncycastle/jce/provider/BouncyCastleProvider

In my IDE (IntelliJ) the import import org.bouncycastle.jce.provider.BouncyCastleProvider appears to be resolved and I can navigate to the location of the class.

Why is the BouncyCastle class not found when I execute the application?

Answer 1

Have you added an entry for the provider in the JCE Security Policy file of the JRE you are using?

JAVA_HOME\jre\lib\security\java.security

n is one more than the last entry already present

security.provider.n=org.bouncycastle.jce.provider.BouncyCastleProvider
