java - example - Cómo ignorar los errores del certificado SSL en Apache HttpClient 4.0

spring resttemplate https

Question

¿Cómo evito errores de certificados SSL no válidos con Apache HttpClient 4.0?

Answer 1

Así es como lo hice -

1. Crear mi propio MockSSLSocketFactory (Clase adjunta a continuación)
2. Úselo para inicializar DefaultHttpClient. La configuración del proxy debe proporcionarse si se utiliza un proxy.

Inicializando DefaultHTTPClient -

SchemeRegistry schemeRegistry = new SchemeRegistry();
    schemeRegistry.register(new Scheme("http", 80, PlainSocketFactory.getSocketFactory()));
    schemeRegistry.register(new Scheme("https", 443, new MockSSLSocketFactory()));
    ClientConnectionManager cm = new SingleClientConnManager(schemeRegistry);

    DefaultHttpClient httpclient = new DefaultHttpClient(cm);

Mock SSL Factory -

public class MockSSLSocketFactory extends SSLSocketFactory {

public MockSSLSocketFactory() throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {
    super(trustStrategy, hostnameVerifier);
}

private static final X509HostnameVerifier hostnameVerifier = new X509HostnameVerifier() {
    @Override
    public void verify(String host, SSLSocket ssl) throws IOException {
        // Do nothing
    }

    @Override
    public void verify(String host, X509Certificate cert) throws SSLException {
        //Do nothing
    }

    @Override
    public void verify(String host, String[] cns, String[] subjectAlts) throws SSLException {
        //Do nothing
    }

    @Override
    public boolean verify(String s, SSLSession sslSession) {
        return true; 
    }
};

private static final TrustStrategy trustStrategy = new TrustStrategy() {
    @Override
    public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
        return true;
    }
};
}

Si está detrás de un proxy, necesita hacer esto:

HttpParams params = new BasicHttpParams();
    params.setParameter(AuthPNames.PROXY_AUTH_PREF, getClientAuthPrefs());

DefaultHttpClient httpclient = new DefaultHttpClient(cm, params);

httpclient.getCredentialsProvider().setCredentials(
                        new AuthScope(proxyHost, proxyPort),
                        new UsernamePasswordCredentials(proxyUser, proxyPass));

Answer 2

Con 4.5.2 fluido tuve que hacer la siguiente modificación para que funcione.

try {
    TrustManager[] trustAllCerts = new TrustManager[] {
       new X509TrustManager() {
    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
        return null;
    }
    public void checkClientTrusted(X509Certificate[] certs, String authType) {  }

    public void checkServerTrusted(X509Certificate[] certs, String authType) {  }
    }
    };

    SSLContext sc = SSLContext.getInstance("SSL");
    sc.init(null, trustAllCerts, new SecureRandom());
    CloseableHttpClient httpClient = HttpClients.custom().setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE).setSslcontext(sc).build();

    String output = Executor.newInstance(httpClient).execute(Request.Get("https://127.0.0.1:3000/something")
                                      .connectTimeout(1000)
                                      .socketTimeout(1000)).returnContent().asString();
    } catch (Exception e) {
    }

Answer 3

Debe crear un SSLContext con su propio TrustManager y crear un esquema HTTPS utilizando este contexto. Aquí está el código,

SSLContext sslContext = SSLContext.getInstance("SSL");

// set up a TrustManager that trusts everything
sslContext.init(null, new TrustManager[] { new X509TrustManager() {
            public X509Certificate[] getAcceptedIssuers() {
                    System.out.println("getAcceptedIssuers =============");
                    return null;
            }

            public void checkClientTrusted(X509Certificate[] certs,
                            String authType) {
                    System.out.println("checkClientTrusted =============");
            }

            public void checkServerTrusted(X509Certificate[] certs,
                            String authType) {
                    System.out.println("checkServerTrusted =============");
            }
} }, new SecureRandom());

SSLSocketFactory sf = new SSLSocketFactory(sslContext);
Scheme httpsScheme = new Scheme("https", 443, sf);
SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(httpsScheme);

// apache HttpClient version >4.2 should use BasicClientConnectionManager
ClientConnectionManager cm = new SingleClientConnManager(schemeRegistry);
HttpClient httpClient = new DefaultHttpClient(cm);

Answer 5

En extensión a la respuesta de ZZ Coder, será bueno anular el nombre del servidor.

// ...
SSLSocketFactory sf = new SSLSocketFactory (sslContext);
sf.setHostnameVerifier(new X509HostnameVerifier() {
    public boolean verify(String hostname, SSLSession session) {
        return true;
    }

    public void verify(String host, String[] cns, String[] subjectAlts) throws SSLException {
    }

    public void verify(String host, X509Certificate cert) throws SSLException {
    }

    public void verify(String host, SSLSocket ssl) throws IOException {
    }
});
// ...

Answer 6

Estamos usando HTTPClient 4.3.5 y probamos que casi todas las soluciones existen en el pero nada. Después de pensar y resolver el problema, llegamos al siguiente código que funciona perfectamente, solo agréguelo antes de crear la instancia de HttpClient.

algún método para llamar al hacer solicitudes de correos ...

SSLContextBuilder builder = new SSLContextBuilder();
    builder.loadTrustMaterial(null, new TrustStrategy() {
        @Override
        public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            return true;
        }
    });

    SSLConnectionSocketFactory sslSF = new SSLConnectionSocketFactory(builder.build(),
            SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

    HttpClient httpClient = HttpClients.custom().setSSLSocketFactory(sslSF).build();
    HttpPost postRequest = new HttpPost(url);

continúe su solicitud en la forma normal

Answer 7

Para Apache HttpClient 4.4:

HttpClientBuilder b = HttpClientBuilder.create();

SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(null, new TrustStrategy() {
    public boolean isTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
        return true;
    }
}).build();
b.setSslcontext( sslContext);

// or SSLConnectionSocketFactory.getDefaultHostnameVerifier(), if you don''t want to weaken
HostnameVerifier hostnameVerifier = SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER;

SSLConnectionSocketFactory sslSocketFactory = new SSLConnectionSocketFactory(sslContext, hostnameVerifier);
Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory>create()
        .register("http", PlainConnectionSocketFactory.getSocketFactory())
        .register("https", sslSocketFactory)
        .build();

// allows multi-threaded use
PoolingHttpClientConnectionManager connMgr = new PoolingHttpClientConnectionManager( socketFactoryRegistry);
b.setConnectionManager( connMgr);

HttpClient client = b.build();

Esto se extrae de nuestra implementación real de trabajo.

Las otras respuestas son populares, pero para HttpClient 4.4 no funcionan. Pasé horas intentando y agotando las posibilidades, pero parece haber habido un cambio y una reubicación de la API extremadamente importante en 4.4.

¡Espero que ayude!

Answer 8

Para aceptar todos los certificados en HttpClient 4.4.x, puede usar el siguiente trazador de líneas al crear el httpClient:

httpClient = HttpClients.custom().setSSLHostnameVerifier(new NoopHostnameVerifier()).setSslcontext(new SSLContextBuilder().loadTrustMaterial(null, (x509Certificates, s) -> true).build()).build();

Answer 9

Para el registro, probado con httpclient 4.3.6 y compatible con el ejecutor de api fluido:

CloseableHttpClient httpClient = HttpClients.custom().
                    setHostnameVerifier(new AllowAllHostnameVerifier()).
                    setSslcontext(new SSLContextBuilder().loadTrustMaterial(null, new TrustStrategy()
                    {
                        public boolean isTrusted(X509Certificate[] arg0, String arg1) throws CertificateException
                        {
                            return true;
                        }

Answer 13

Si está utilizando Apache httpClient 4.5.x , intente esto:

public static void main(String... args)  {

    try (CloseableHttpClient httpclient = createAcceptSelfSignedCertificateClient()) {
        HttpGet httpget = new HttpGet("https://example.com");
        System.out.println("Executing request " + httpget.getRequestLine());

        httpclient.execute(httpget);
        System.out.println("----------------------------------------");
    } catch (NoSuchAlgorithmException | KeyStoreException | KeyManagementException | IOException e) {
        throw new RuntimeException(e);
    }
}

private static CloseableHttpClient createAcceptSelfSignedCertificateClient()
        throws KeyManagementException, NoSuchAlgorithmException, KeyStoreException {

    // use the TrustSelfSignedStrategy to allow Self Signed Certificates
    SSLContext sslContext = SSLContextBuilder
            .create()
            .loadTrustMaterial(new TrustSelfSignedStrategy())
            .build();

    // we can optionally disable hostname verification. 
    // if you don''t want to further weaken the security, you don''t have to include this.
    HostnameVerifier allowAllHosts = new NoopHostnameVerifier();

    // create an SSL Socket Factory to use the SSLContext with the trust self signed certificate strategy
    // and allow all hosts verifier.
    SSLConnectionSocketFactory connectionFactory = new SSLConnectionSocketFactory(sslContext, allowAllHosts);

    // finally create the HttpClient using HttpClient factory methods and assign the ssl socket factory
    return HttpClients
            .custom()
            .setSSLSocketFactory(connectionFactory)
            .build();
}

Answer 14

Si está utilizando la API con fluidez , debe configurarla a través del Executor :

Executor.unregisterScheme("https");
SSLSocketFactory sslSocketFactory = new SSLSocketFactory(sslContext,
                                  SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
Executor.registerScheme(new Scheme("https", 443, sslSocketFactory));

... donde sslContext es el SSLContext creado como se muestra en la respuesta del ZZ Coder .

Después de eso, puede hacer sus solicitudes http como:

String responseAsString = Request.Get("https://192.168.1.0/whatever.json")
                         .execute().getContent().asString();

_{Nota: probado con HttpClient 4.2}

Answer 15

Si se encuentra con este problema al utilizar AmazonS3Client, que incorpora Apache HttpClient 4.1, simplemente necesita definir una propiedad del sistema como esta para que el comprobador de certificados SSL esté relajado:

-Dcom.amazonaws.sdk.disableCertChecking = true

Travesura manejada

Answer 16

Si todo lo que quiere hacer es deshacerse de los errores de nombres de host no válidos, puede hacer lo siguiente:

HttpClient httpClient = new DefaultHttpClient();
SSLSocketFactory sf = (SSLSocketFactory)httpClient.getConnectionManager()
    .getSchemeRegistry().getScheme("https").getSocketFactory();
sf.setHostnameVerifier(new AllowAllHostnameVerifier());

Answer 17

Simplemente tuve que hacer esto con httpclient-4.5 y parece que han desaprobado algunas cosas desde 4.4, así que aquí está el fragmento que me funciona y usa la API más reciente:

final SSLContext sslContext = new SSLContextBuilder()
        .loadTrustMaterial(null, (x509CertChain, authType) -> true)
        .build();

return HttpClientBuilder.create()
        .setSSLContext(sslContext)
        .setConnectionManager(
                new PoolingHttpClientConnectionManager(
                        RegistryBuilder.<ConnectionSocketFactory>create()
                                .register("http", PlainConnectionSocketFactory.INSTANCE)
                                .register("https", new SSLConnectionSocketFactory(sslContext,
                                        NoopHostnameVerifier.INSTANCE))
                                .build()
                ))
        .build();

Answer 18

Solo para el registro, hay una manera mucho más simple de lograr lo mismo con HttpClient 4.1

    SSLSocketFactory sslsf = new SSLSocketFactory(new TrustStrategy() {

        public boolean isTrusted(
                final X509Certificate[] chain, String authType) throws CertificateException {
            // Oh, I am easy...
            return true;
        }

    });

Answer 19

Todas las otras respuestas fueron obsoletas o no funcionaron para HttpClient 4.3.

Aquí hay una manera de permitir todos los nombres de host al construir un cliente http.

CloseableHttpClient httpClient = HttpClients
    .custom()
    .setHostnameVerifier(AllowAllHostnameVerifier.INSTANCE)
    .build();

O si está utilizando la versión 4.4 o posterior, la llamada actualizada se ve así:

CloseableHttpClient httpClient = HttpClients
    .custom()
    .setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
    .build();

una versión de trabajo completa para Apache HttpClient 4.1.3 (basado en el código de oleg anterior, pero todavía necesitaba un allow_all_hostname_verifier en mi sistema):

private static HttpClient trustEveryoneSslHttpClient() {
    try {
        SchemeRegistry registry = new SchemeRegistry();

        SSLSocketFactory socketFactory = new SSLSocketFactory(new TrustStrategy() {

            public boolean isTrusted(final X509Certificate[] chain, String authType) throws CertificateException {
                // Oh, I am easy...
                return true;
            }

        }, org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

        registry.register(new Scheme("https", 443, socketFactory));
        ThreadSafeClientConnManager mgr = new ThreadSafeClientConnManager(registry);
        DefaultHttpClient client = new DefaultHttpClient(mgr, new DefaultHttpClient().getParams());
        return client;
    } catch (GeneralSecurityException e) {
        throw new RuntimeException(e);
    }
}

Tenga en cuenta que estoy volviendo a lanzar todas las excepciones porque realmente, ¡no hay mucho que pueda hacer si algo de esto falla en un sistema real!

Apache HttpClient 4.5.5

HttpClient httpClient = HttpClients
            .custom()
            .setSSLContext(new SSLContextBuilder().loadTrustMaterial(null, TrustAllStrategy.INSTANCE).build())
            .setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
            .build();

No se ha usado ninguna API obsoleta.

Caso de prueba verificable simple:

package org.apache.http.client.test;

public class ApacheHttpClientTest {

    private HttpClient httpClient;

    @Before
    public void initClient() throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException {
        httpClient = HttpClients
                .custom()

                .setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
                .build();
    }

    @Test
    public void apacheHttpClient455Test() throws IOException {
        executeRequestAndVerifyStatusIsOk("https://expired.badssl.com");
        executeRequestAndVerifyStatusIsOk("https://wrong.host.badssl.com");
        executeRequestAndVerifyStatusIsOk("https://self-signed.badssl.com");

        HttpUriRequest request = new HttpGet(url);

        HttpResponse response = httpClient.execute(request);
        int statusCode = response.getStatusLine().getStatusCode();

        assert statusCode == 200;
    }
}
