Add the Bouncy Castle provider jar to the `$JAVA_HOME/jre/lib/ext` directory 1. Create a Bouncy Castle provider entry in the `$JAVA_HOME/jre/lib/security/java.security` file The entry to `java.security` will look something like the following: security.provider.N=org.bouncycastle.jce.provider.BouncyCastleProvider Replace `N` with the order of precedence you would like to give Bouncy Castle in comparison to the other providers in the file. **Recommended** would be the last entry in the list -- `N` being the higest number in the list. **Warning** that configuring Bouncy Castle as the first provider, `security.provider.1`, may cause JVM errors.
