javax.net.ssl.SSLPeerUnverifiedException: Host name does not match the certificate subject provided by the peer

问题

I follow many links on stackoverflow and tried many solutions, but none of them worked for me. I'm using WSO2 API manager version 1.9.1. I am facing following error:

Exception in thread "main" javax.net.ssl.SSLPeerUnverifiedException: Host name 'XXXXXXXXX' does not match the certificate subject provided by the peer (CN=localhost, O=WSO2, L=Mountain View, ST=CA, C=US)

I developed the following Java code. Please help me what's going wrong here. I need to connect insecure way and allow connections to SSL sites without certs.

public static void main(String[] args) throws ClientProtocolException, IOException, NoSuchAlgorithmException, KeyStoreException, KeyManagementException {
        SSLContextBuilder builder = new SSLContextBuilder();
        builder.loadTrustMaterial(null, new TrustSelfSignedStrategy());
        SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(builder.build());

        Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
                .register("http", new PlainConnectionSocketFactory())
                .register("https", sslsf)
                .build();

        PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(registry);
        cm.setMaxTotal(2000);//max connection

    CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsf)
                .setConnectionManager(cm).build();

        HttpGet httpGet = new HttpGet("https://XXXXXXXXXX:8243/token");
        CloseableHttpResponse response = httpclient.execute(httpGet);

        String json =" {\"data\":\"grant_type=password&username=test&password=test123\"}";

        try {
            HttpPost httpost = new HttpPost(url);
            httpost.setHeader("Content-Type", "application/x-www-form-urlencoded");
            httpost.setHeader("Authorization", "Basic XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX");

            httpost.setEntity(new StringEntity(json));

            HttpResponse httpResponse = httpclient.execute(httpost);

            System.out.println(httpResponse.getStatusLine());
        }
        finally {
            response.close();
        }

        String responseString1 = new BasicResponseHandler().handleResponse(response);
        System.out.println("Response : "+responseString1);
    }

I have spent an hour trying to fix the same issue. This is what I come up with:

final SSLConnectionSocketFactory sslsf;
try {
    sslsf = new SSLConnectionSocketFactory(SSLContext.getDefault(),
            NoopHostnameVerifier.INSTANCE);
} catch (NoSuchAlgorithmException e) {
    throw new RuntimeException(e);
}

final Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
        .register("http", new PlainConnectionSocketFactory())
        .register("https", sslsf)
        .build();

final PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(registry);
cm.setMaxTotal(100);
httpClient = HttpClients.custom()
        .setSSLSocketFactory(sslsf)
        .setConnectionManager(cm)
        .build();

Hopefully, it works and does not use any deprecated code (httpclient 4.4.1).

Replace this

CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsf)
            .setConnectionManager(cm).build();

with

CloseableHttpClient httpclient = HttpClients.custom()
            .setSSLSocketFactory(sslsf)
            .setConnectionManager(cm)
            .setHostnameVerifier(SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER)
            .build();

If the certificate isn't signed (not even self-signed), then you can do

import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

public class TrustAllStrategy implements TrustStrategy {
    @Override
    public boolean isTrusted(X509Certificate[] chain, String authType)
            throws CertificateException {
        return true;
    }
}

Then

builder.loadTrustMaterial(new TrustAllStrategy());

EDIT: this

SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
            sslcontext, //for you this is builder.build()
            SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER
);

Thanks to all the solutions. I have been trying all the solutions available online for 1.5 days now and finally it worked now. Here is the working code

 SSLContextBuilder builder = new SSLContextBuilder();
 builder.loadTrustMaterial(null, new TrustSelfSignedStrategy());
 SSLConnectionSocketFactory sslConnectionSocketFactory = new SSLConnectionSocketFactory(builder.build(), NoopHostnameVerifier.INSTANCE);
 Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
            .register("http", new PlainConnectionSocketFactory())
            .register("https", sslConnectionSocketFactory)
            .build();

 PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(registry);
 cm.setMaxTotal(100);
 CloseableHttpClient httpclient = HttpClients.custom()
            .setSSLSocketFactory(sslConnectionSocketFactory)
            .setConnectionManager(cm)
            .build();
 HttpPost httpPost = new HttpPost(url);
 httpPost.setEntity(postEntity);
 httpPost.expectContinue();
 CloseableHttpResponse response = httpclient.execute(httpPost);

This is what I came up with:

 SSLContextBuilder sslcontext = new SSLContextBuilder();
 sslcontext.loadTrustMaterial(null, new TrustSelfSignedStrategy());
 httpclient = HttpAsyncClients.custom().setSSLContext(sslcontext.build()).setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
      .build();

After trying most of the solution suggested on this page and other related stackoverflow discussions, I found AJC's response above works with apache httpclient version 4.5.

Reason: While creating SSLConnectionSocketFactory if the HostVerifier is not specified in the constructor, it does not get set and the DefaultHostVerifier is used. So line 3 of AJC's solutionmakes the difference.

(Atleast this is the behavior in apache httpclient 4.5.3 )
