Autenticazione reciproca con certificati x509 utilizzando HttpClient 4.0.1

Question

Qualcuno ha qualche suggerimento amichevole su come eseguire l'autenticazione del client tramite un certificato x509 utilizzando HTTPClient 4.0.1?

Grazie per il vostro tempo.

Answer 1

Ecco un codice per iniziare. KeyStore è l'oggetto che contiene il certificato client. Se il server utilizza un certificato autofirmato o un certificato non firmato da una CA come riconosciuto dalla JVM nel file cacerts incluso, sarà necessario utilizzare uno TrustStore. In caso contrario, utilizzare il file cacerts predefinite, passare null per SSLSockeFactory per l'argomento truststore ..

import org.apache.http.conn.scheme.Scheme; 
import org.apache.http.conn.scheme.SchemeRegistry; 
import org.apache.http.conn.ssl.SSLSocketFactory; 
import org.apache.http.impl.client.DefaultHttpClient; 
import org.apache.http.impl.conn.tsccm.ThreadSafeClientConnManager; 
import org.apache.http.params.BasicHttpParams; 
import org.apache.http.params.HttpParams; 

... 

final HttpParams httpParams = new BasicHttpParams(); 

// load the keystore containing the client certificate - keystore type is probably jks or pkcs12 
final KeyStore keystore = KeyStore.getInstance("pkcs12"); 
InputStream keystoreInput = null; 
// TODO get the keystore as an InputStream from somewhere 
keystore.load(keystoreInput, "keystorepassword".toCharArray()); 

// load the trustore, leave it null to rely on cacerts distributed with the JVM - truststore type is probably jks or pkcs12 
KeyStore truststore = KeyStore.getInstance("pkcs12"); 
InputStream truststoreInput = null; 
// TODO get the trustore as an InputStream from somewhere 
truststore.load(truststoreInput, "truststorepassword".toCharArray()); 

final SchemeRegistry schemeRegistry = new SchemeRegistry(); 
schemeRegistry.register(new Scheme("https", new SSLSocketFactory(keystore, keystorePassword, truststore), 443)); 

final DefaultHttpClient httpClient = new DefaultHttpClient(new ThreadSafeClientConnManager(httpParams, schemeRegistry), httpParams);

Un'altra soluzione (copiato da un altro esempio). Ho usato lo stesso keystore sia per 'trusting' (trustStore) sia per autenticarmi (keyStore).

KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType()); 
FileInputStream instream = new FileInputStream(new File("miller.keystore")); 
try { 
    trustStore.load(instream, "pw".toCharArray()); 
} finally { 
    instream.close(); 
} 

SSLContext sslcontext = SSLContexts.custom() 
     .loadTrustMaterial(trustStore) /* this key store must contain the certs needed & trusted to verify the servers cert */ 
     .loadKeyMaterial(trustStore, "pw".toCharArray()) /* this keystore must contain the key/cert of the client */ 
     .build(); 

SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslcontext, 
     SSLConnectionSocketFactory.BROWSER_COMPATIBLE_HOSTNAME_VERIFIER); 
CloseableHttpClient httpclient = HttpClients.custom() 
     .setSSLSocketFactory(sslsf) 
     .build(); 
try { 

    HttpGet httpget = new HttpGet("https://localhost"); 

    System.out.println("executing request" + httpget.getRequestLine()); 

    CloseableHttpResponse response = httpclient.execute(httpget); 
    try { 
     HttpEntity entity = response.getEntity(); 

     System.out.println("----------------------------------------"); 
     System.out.println(response.getStatusLine()); 
     if (entity != null) { 
      System.out.println("Response content length: " + entity.getContentLength()); 
     } 
     EntityUtils.consume(entity); 
    } finally { 
     response.close(); 
    } 
} finally { 
    httpclient.close(); 
}

Ho utilizzato quanto segue da un codice di esempio sul sito Web di HttpClient (contesto SSL personalizzato se non ricordo male).

{ 
    KeyStore keyStore = KeyStore.getInstance("PKCS12"); //client certificate holder 
    FileInputStream instream = new FileInputStream(new File(
      "client-p12-keystore.p12")); 
    try { 
     trustStore.load(instream, "password".toCharArray()); 
    } finally { 
     instream.close(); 
    } 

    // Trust own CA and all self-signed certs 
    SSLContext sslcontext = SSLContexts.custom() 
      .loadKeyMaterial(keyStore, "password".toCharArray()) 
      // .loadTrustMaterial(trustStore, new TrustSelfSignedStrategy()) //if you have a trust store 
      .build(); 
    // Allow TLSv1 protocol only 
    SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
      sslcontext, new String[] { "TLSv1" }, null, 
      SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER); 
    CloseableHttpClient httpclient = HttpClients 
      .custom() 
      .setHostnameVerifier(
        SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER) //todo 
      .setSSLSocketFactory(sslsf).build(); 
    try { 

     HttpGet httpget = new HttpGet("https://localhost:8443/secure/index"); 

     System.out.println("executing request" + httpget.getRequestLine()); 

     CloseableHttpResponse response = httpclient.execute(httpget); 
     try { 
      HttpEntity entity = response.getEntity(); 

      System.out.println("----------------------------------------"); 
      System.out.println(response.getStatusLine()); 
      if (entity != null) { 
       System.out.println("Response content length: " 
         + entity.getContentLength()); 
      } 
      EntityUtils.consume(entity); 
     } finally { 
      response.close(); 
     } 
    } finally { 
     httpclient.close(); 
    } 
}
