Hi Experts, We want to integrate bc-fips in our application. We have changed our standalone.xml (Wildfly) to use BCKFS keystore and changed java.security to use security.provider.1=org.bouncycastle.jcajce.provider.BouncyCastleFipsProvider and keystore.type=bcfks Copied bc-fips-1.0.1.jar to jre/lib/ext /modules/system/layers/base/org/bouncycastle/fips But when I start my application, I see following error, Caused by: java.lang.NoClassDefFoundError: org/bouncycastle/jce/provider/BouncyCastleProvider at org.keycloak.common.util.PemUtils.<clinit>(PemUtils.java:41) at org.keycloak.adapters.KeycloakDeploymentBuilder.internalBuild(KeycloakDeploymentBuilder.java:63) at org.keycloak.adapters.KeycloakDeploymentBuilder.build(KeycloakDeploymentBuilder.java:137) at org.keycloak.adapters.undertow.KeycloakServletExtension.handleDeployment(KeycloakServletExtension.java:135) at io.undertow.servlet.core.DeploymentManagerImpl.handleExtensions(DeploymentManagerImpl.java:252) at io.undertow.servlet.core.DeploymentManagerImpl.deploy(DeploymentManagerImpl.java:152) at org.wildfly.extension.undertow.deployment.UndertowDeploymentService.startContext(UndertowDeploymentService.java:100) at org.wildfly.extension.undertow.deployment.UndertowDeploymentService$1.run(UndertowDeploymentService.java:82) Not sure what I am missing. Could any one help me here. -Srini
