Elytron discovery of providers from BC module does not work without class-names ------------------------------------------------------------------------------- Key: WFLY-10223 URL: https://issues.jboss.org/browse/WFLY-10223 Project: WildFly Issue Type: Bug Components: Security Affects Versions: 12.0.0.Final Reporter: Jan Kalina Assignee: Jan Kalina Labels: fips, provider, ssl If I register provider loader to load providers from org.bouncycastle module, no provider is loaded. {code} [standalone@localhost:9990 /] /subsystem=elytron/provider-loader=bc:add(module=org.bouncycastle) {"outcome" => "success"} [standalone@localhost:9990 /] /subsystem=elytron/provider-loader=bc:read-attribute(name=loaded-providers) { "outcome" => "success", "result" => undefined } {code} But if I specify {{class-names}} attribute, provider is loaded as expected. {code} [standalone@localhost:9990 /] /subsystem=elytron/provider-loader=bc2:add(class-names=[org.bouncycastle.jce.provider.BouncyCastleProvider], module=org.bouncycastle) {"outcome" => "success"} [standalone@localhost:9990 /] /subsystem=elytron/provider-loader=bc2:read-attribute(name=loaded-providers) { "outcome" => "success", "result" => [{ "name" => "BC", "info" => "BouncyCastle Security Provider v1.56", "version" => 1.56, "services" => [ { "type" => "MessageDigest", "algorithm" => "GOST3411", "class-name" => "org.bouncycastle.jcajce.provider.digest.GOST3411$Digest" }, { "type" => "Mac", "algorithm" => "HMACGOST3411", "class-name" => "org.bouncycastle.jcajce.provider.digest.GOST3411$HashMac" }, { "type" => "KeyGenerator", "algorithm" => "HMACGOST3411", "class-name" => "org.bouncycastle.jcajce.provider.digest.GOST3411$KeyGenerator" }, { "type" => "MessageDigest", "algorithm" => "GOST3411-2012-256", "class-name" => "org.bouncycastle.jcajce.provider.digest.GOST3411$Digest2012_256" }, ... {code} Check provider discovery feature. {code:java|title=ProviderDefinitions} ClassLoader classLoader = doPrivileged((PrivilegedExceptionAction<ClassLoader>) () -> resolveClassLoader(module)); final List<Provider> loadedProviders; if (classNames != null) { loadedProviders = new ArrayList<>(classNames.length); for (String className : classNames) { Class<? extends Provider> providerClazz = classLoader.loadClass(className).asSubclass(Provider.class); loadedProviders.add(providerClazz.newInstance()); } } else { loadedProviders = new ArrayList<>(); ServiceLoader<Provider> loader = ServiceLoader.load(Provider.class, classLoader); loader.forEach(loadedProviders::add); } {code}
