PKIX path validation failed: java.security.cert.CertPathValidatorException: signature check failed

Question

From Pro Spring Security book by Carlo Scarioni, I'm trying to integrate Spring Application with CAS Server. I followed every step that the book instructed, still I'm stuck with this error. Please help me out.

The SSL handshake exception will occur if cas server to cas client (jar files will behave as client) communication is not happened, First check the network things like communication between both servers, firewall and port blocking, if every thing is good then this problem is because of SSL certificate, make sure to use the same certificate in both CAS server and client(Spring security app) applications.

As i can't comment yet, i'll just extend to @Kamal's answer. I was learning through the same book, but i was using Tomcat as a difference, so i can't really give you the same answer as i've never used Jetty: As he said, your SSL is not working as it should. The certificate is not being accepted by your browser and/or server, so it can't authenticate, and thus, SSL handshake gets rejected. You need to be sure that you've added the certificate CAS.crt to your JVM cacerts, as he explains on the book(198-199), and check if it's correctly there . And then you need to add the jetty-ssl.keystore to Jetty, with the password that you used, so that it can used to make the right connection. Also, you need to be positively sure that it's written localhost as the cn name, as it won't work otherwise. This would change depending on your enviroment(production, testing, just learning...), but this is the necessary for making it work as the book described. Hope that i'm not too off here, but i hope it helped.

I have faced this issue and found that SSL certificate was expired. After replacing expired SSL certificate by latest certificate the issue was resolved.

Check your system date. It worked for me when I corrected it. This usually comes in SLES distros.

I am using Spring 2.2.5 now with Java 11 version.

Try to add into the Spring Application context the RestTemplate bean, in order to accept all the certificates just like this:

    @Bean
    public RestTemplate restTemplate(RestTemplateBuilder builder) throws NoSuchAlgorithmException, KeyManagementException {
        TrustManager[] trustAllCerts = new TrustManager[]{
                new X509TrustManager() {
                    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                        return new X509Certificate[0];
                    }

                    public void checkClientTrusted(
                            java.security.cert.X509Certificate[] certs, String authType) {
                    }

                    public void checkServerTrusted(
                            java.security.cert.X509Certificate[] certs, String authType) {
                    }
                }
        };
        SSLContext sslContext = SSLContext.getInstance("SSL");
        sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
        CloseableHttpClient httpClient = HttpClients.custom()
                .setSSLContext(sslContext)
                .setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
                .build();
        HttpComponentsClientHttpRequestFactory customRequestFactory = new HttpComponentsClientHttpRequestFactory();
        customRequestFactory.setHttpClient(httpClient);
        return builder.requestFactory(() -> customRequestFactory).build();
    }

Then, in your client class with the server communication, you have to add the bean RestTemplate restTemplate and pass it in the constructor.

Then, in a method, you have to write the remote rest end point invocation like this:

    private YourSpecificResponseJSONClass getYourRemoteResponse() {
        YourSpecificResponseJSONClass resp = getYourDefaultJSONResponseInCaseOfAnyException();
        try {
            resp = restTemplate.getForObject("<yourRemoteURL>", YourSpecificResponseJSONClass.class);
        } catch (Throwable t) {
           //log whatever
        }
        return resp;
    }

If you just accept any certificate, than it does not provide you any protection! — Meier, Jan 05 '21 at 13:50

Below solution is working fine for me.

SslContext sslContext = SslContextBuilder
            .forClient()
            .trustManager(InsecureTrustManagerFactory.INSTANCE)
            .build();

  HttpClient httpClient = HttpClient.create().secure(t -> 
    t.sslContext(sslContext) );
    WebClient webClient =  WebClient.builder()
             .baseUrl("any-url")
            .clientConnector(new ReactorClientHttpConnector(httpClient))
            .build();
