Java can't send https request "unable to find valid certification path"

I am trying to access a sandbox api over https: https://api-sandbox.rabobank.nl/openapi/sandbox but I get this error when sending request: https://pastebin.com/5X4h3wsu

I tried adding the certificate from above mentioned url to jre11, jdk8, jdk7 truststores and tried switching my project jdk/jre to those versions. the error doesn't change however. I also tried setting this as vm options: -Dcom.sun.net.ssl.checkRevocation=false also no luck. when i enable: -Djavax.net.debug=ssl (with java 8, option doesn't work with 11) I got this output to console: https://pastebin.com/5L7Lei8J

And here's all my code, it's not much because this app was meant to test the api with a minimal working example. Application.java:

package com.thebooks;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.web.client.RestTemplate;

import java.io.File;
import java.security.KeyStore;

@SpringBootApplication
public class Application {

    static {
        System.setProperty("jdk.tls.client.protocols", "TLSv1.2");
        System.setProperty("https.protocols", "TLSv1.2");
        System.setProperty("javax.net.ssl.trustStore", System.getProperty("user.dir") + "/key/cert.p12");
        System.setProperty("javax.net.ssl.trustStorePassword", "secret");
        System.setProperty("javax.net.ssl.keyStore",  System.getProperty("user.dir") + "/key/key.p12");
        System.setProperty("javax.net.ssl.keyStorePassword", "secret");

        javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier(
                new javax.net.ssl.HostnameVerifier() {

                    public boolean verify(String hostname,
                                          javax.net.ssl.SSLSession sslSession) {
                        // TODO: CODE TO VERIFY Host
                        return true;
                    }
                });
    }

    @Bean
    public RestTemplate template() throws Exception {
        return new RestTemplate();
    }

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

HttpClient.java:

package com.thebooks.httpclient;

import com.thebooks.enums.EScope;
import com.thebooks.providers.PropertyProvider;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Component;
import org.springframework.web.client.RestTemplate;

@Component
public class HttpClient implements CommandLineRunner {
    private String apiUrl = "https://api-sandbox.rabobank.nl/openapi/sandbox/";

    private final RestTemplate template;
    private PropertyProvider propProvider = new PropertyProvider();
    private final String CLIENT_ID = propProvider.get("client.id");

    public HttpClient(RestTemplate template) {
        this.template = template;
    }

    @Override
    public void run(String... args) throws Exception {
        ResponseEntity<Object> response = template.getForEntity(
                apiUrl + "oauth2/authorize?client_id=" + CLIENT_ID +
                        "&response_type=code&scope=" + EScope.AIS_BALANCES_READ.getValue(),
                Object.class);
        System.out.println(response.getStatusCode());
        System.out.println(response.getBody());
        System.out.println(response.getHeaders());
    }
}

I got most of this code from this website who owns the api I'm trying to use: https://developer-sandbox.rabobank.nl/mutual-tls I'm pretty sure it has to do with their certificate not being trusted by my pc/app. But like I said I added their certificate to all 3 cacerts of all 3 versions of java that I have...

Solution

  • What I see in Your logs is:

    trustStore is: C:\Projects\Java\rabobank-test\key\cert.p12
trustStore type is : jks
trustStore provider is :
init truststore
adding as trusted cert:
  Subject: CN=BAS, O=Internet Widgits Pty Ltd, L=rotterdam, ST=Zuid-Holland, C=NL
  Issuer:  CN=BAS, O=Internet Widgits Pty Ltd, L=rotterdam, ST=Zuid-Holland, C=NL

 keyStore is : C:\Projects\Java\rabobank-test/key/key.p12
...

    That is, You have had only one self-signed certificate in trusstore. But the server is using:

    Which is neighther self-signed nor looks at any place to be not verifyable with default truststore and SSL settings.

    So just disable the lines

            System.setProperty("javax.net.ssl.trustStore", System.getProperty("user.dir") + "/key/cert.p12");
        System.setProperty("javax.net.ssl.trustStorePassword", "secret");

    of if You need that cert in truststore, optimally take the official trustore delivered with java and add the cert you have in yout cert.p12 to that - or add any other certificates from the chain the server offers to that stripped down custom truststore. (Ideally the root certificate "CN=DigiCert High Assurance EV Root CA, OU=www.digicert.com, O=DigiCert Inc, C=US" which You get at digicert or probably in all current default trustsores and the like delivered with andy application or operating system.)
