“无法在Camel组件测试中找到所请求目标的有效证书路径”

Question

i am trying to develop and test a camel endpoint. I now want to test SSL connectivity. Whenever i run the test (which tries to do a mutual SSL authentication) i get the error "unable to find valid certification path to requested target". My certificate chain looks like this for client and server. Both are identical besides an ID. CA -> SubCA -> Client1 (used as "client") -> Client2 (used as "server"

I created a PKCS12 file for both clients and imported CA, SubCA and client certificate into a keystore:

keytool -keystore store.jks -importcert -alias ca -file test_ca_certs/rootca.cert
keytool -keystore store.jsk -importcert -alias subca -file test_ca_certs/subca.cert
keytool -v -importkeystore -srckeystore source.p12 -srcstoretype PKCS12 -destkeystore store.jsk -deststoretype JKS

So lets say, i have a store for client and server only differing in the client cert. I tried to avoid having different trust/keystores, but this should be fine, right?

Pretty much directly taken from camel source examples, i have this methods used in my test class:

private static SSLContextParameters defineClientSSLContextClientParameters() {

    KeyStoreParameters ksp = new KeyStoreParameters();
    ksp.setResource(Thread.currentThread().getContextClassLoader().getResource("jsse/source.jks").toString());
    ksp.setPassword(PWD);

    KeyManagersParameters kmp = new KeyManagersParameters();
    kmp.setKeyPassword(PWD);
    kmp.setKeyStore(ksp);

    TrustManagersParameters tmp = new TrustManagersParameters();
    tmp.setKeyStore(ksp);

    SSLContextServerParameters scsp = new SSLContextServerParameters();
    scsp.setClientAuthentication(ClientAuthentication.REQUIRE.name());

    SSLContextParameters sslContextParameters = new SSLContextParameters();
    sslContextParameters.setKeyManagers(kmp);
    sslContextParameters.setTrustManagers(tmp);
    sslContextParameters.setServerParameters(scsp);

    return sslContextParameters;
}

private static SSLContextParameters defineServerSSLContextParameters() {
       KeyStoreParameters ksp = new KeyStoreParameters();
       ksp.setResource(Thread.currentThread().getContextClassLoader().getResource("jsse/target.jks").toString());
       ksp.setPassword(PWD);

       KeyManagersParameters kmp = new KeyManagersParameters();
       kmp.setKeyPassword(PWD);
       kmp.setKeyStore(ksp);

       TrustManagersParameters tmp = new TrustManagersParameters();
       tmp.setKeyStore(ksp);

       SSLContextServerParameters scsp = new SSLContextServerParameters();
       scsp.setClientAuthentication(ClientAuthentication.REQUIRE.name());

       SSLContextParameters sslContextParameters = new SSLContextParameters();
       sslContextParameters.setKeyManagers(kmp);
       sslContextParameters.setTrustManagers(tmp);
       sslContextParameters.setServerParameters(scsp);


       return sslContextParameters;
}

@Override
protected RouteBuilder[] createRouteBuilders() throws Exception {
    RouteBuilder[] rbs = new RouteBuilder[2];

    // A protocol consumer
    rbs[0] = new RouteBuilder() {
        public void configure() {

            // Needed to configure TLS on the client side
            WsComponent wsComponent = (WsComponent) context.getComponent("protocolclient");
            wsComponent.setSslContextParameters(defineClientSSLContextClientParameters());

            from("direct:input").routeId("foo")
                .log(">>> Message from direct to WebSocket Client : ${body}")
                .to("protocolclient://localhost:9292/echo")
                .log(">>> Message from WebSocket Client to server: ${body}");
            }
    };

    // A protocol provider
    rbs[1] = new RouteBuilder() {
        public void configure() {

                // Needed to configure TLS on the server side
                WebsocketComponent websocketComponent = (WebsocketComponent) context.getComponent("protocolserver");
                websocketComponent.setSslContextParameters(defineServerSSLContextParameters());

                // This route is set to use TLS, referring to the parameters set above
                from("protocolserver:localhost:9292/echo")
                .log(">>> Message from WebSocket Server to mock: ${body}")
                .to("mock:result");
        }
    };
    return rbs;
}

For completeness, here is the config file i used to generate the client certs:

Did i do some obvious mistake? I am quite puzzled :(

Thanks!

EDIT: I added some debug output. Is this how it should look like?

Answer 1

I finally found the solution. I only set debugging to SSL. This was my mistake. I would have needed to set the debug output to "all". Then i can see this error message:

Caused by: sun.security.validator.ValidatorException: Extended key usage does not permit use for TLS server authentication

This is much more specific. To fix that, indeed i needed to change my extended key usage to this:

keyUsage            = digitalSignature, keyEncipherment, nonRepudiation
extendedKeyUsage    = clientAuth, serverAuth

Thank you very much!
