如何在apache HttpClient上设置TLS版本

Question

如何在HttpClient上更改支持的TLS版本？

我正在做:

SSLContext sslContext = SSLContext.getInstance("TLSv1.1");
sslContext.init(
    keymanagers.toArray(new KeyManager[keymanagers.size()]),
    null,
    null);

SSLSocketFactory socketFactory = new SSLSocketFactory(sslContext, new String[]{"TLSv1.1"}, null, null);
Scheme scheme = new Scheme("https", 443, socketFactory);
SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(scheme);
BasicClientConnectionManager cm = new BasicClientConnectionManager(schemeRegistry);
httpClient = new DefaultHttpClient(cm);

但是当我检查创建的套接字时,它仍然说支持的协议是TLSv1.0,TLSv1.1和TLSv1.2.

实际上我只是希望它停止使用TLSv1.2,对于这个特定的HttpClient.

解决方案是:

SSLContext sslContext = SSLContexts.custom()
    .useTLS()
    .build();

SSLConnectionSocketFactory f = new SSLConnectionSocketFactory(
    sslContext,
    new String[]{"TLSv1", "TLSv1.1"},   
    null,
    BROWSER_COMPATIBLE_HOSTNAME_VERIFIER);

httpClient = HttpClients.custom()
    .setSSLSocketFactory(f)
    .build();

这需要org.apache.httpcomponents.httpclient 4.3.x.

这就是我如何使用httpClient 4.5(根据Olive Tree请求):

CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(
        new AuthScope(AuthScope.ANY_HOST, 443),
        new UsernamePasswordCredentials(this.user, this.password));

SSLContext sslContext = SSLContexts.createDefault();

SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext,
        new String[]{"TLSv1", "TLSv1.1"},
        null,
        new NoopHostnameVerifier());

CloseableHttpClient httpclient = HttpClients.custom()
        .setDefaultCredentialsProvider(credsProvider)
        .setSSLSocketFactory(sslsf)
        .build();

return httpclient;

HttpClient-4.5,使用TLSv1.2,你必须这样编码:

 //Set the https use TLSv1.2
private static Registry<ConnectionSocketFactory> getRegistry() throws KeyManagementException, NoSuchAlgorithmException {
    SSLContext sslContext = SSLContexts.custom().build();
    SSLConnectionSocketFactory sslConnectionSocketFactory = new SSLConnectionSocketFactory(sslContext,
            new String[]{"TLSv1.2"}, null, SSLConnectionSocketFactory.getDefaultHostnameVerifier());
    return RegistryBuilder.<ConnectionSocketFactory>create()
            .register("http", PlainConnectionSocketFactory.getSocketFactory())
            .register("https", sslConnectionSocketFactory)
            .build();
}

public static void main(String... args) {
    try {
        //Set the https use TLSv1.2
        PoolingHttpClientConnectionManager clientConnectionManager = new PoolingHttpClientConnectionManager(getRegistry());
        clientConnectionManager.setMaxTotal(100);
        clientConnectionManager.setDefaultMaxPerRoute(20);
        HttpClient client = HttpClients.custom().setConnectionManager(clientConnectionManager).build();
        //Then you can do : client.execute(HttpGet or HttpPost);
    } catch (KeyManagementException | NoSuchAlgorithmException e) {
        e.printStackTrace();
    }
}

对于使用TLSv1.2的HttpClient-4.1,代码将是这样的:

        SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
        sslContext.init(null, null, new SecureRandom());
        SSLSocketFactory sf = new SSLSocketFactory(sslContext);
        Scheme httpsScheme = new Scheme("https", 443, sf);
        SchemeRegistry schemeRegistry = new SchemeRegistry();
        schemeRegistry.register(httpsScheme);
        ClientConnectionManager cm =  new        SingleClientConnManager(schemeRegistry);
        HttpClient client = new DefaultHttpClient(cm);

       // Use client to make the connection and get the results.

使用HttpClientBuilder中的HttpClient 4.5.x有一个自定义HttpClientConnectionManager使用缺省值HttpClientBuilder：

SSLConnectionSocketFactory sslConnectionSocketFactory = 
    new SSLConnectionSocketFactory(SSLContexts.createDefault(),          
                                   new String[] { "TLSv1.2" },                                            
                                   null, 
           SSLConnectionSocketFactory.getDefaultHostnameVerifier());

PoolingHttpClientConnectionManager poolingHttpClientConnectionManager =
    new PoolingHttpClientConnectionManager(
        RegistryBuilder.<ConnectionSocketFactory> create()
                       .register("http",
                                 PlainConnectionSocketFactory.getSocketFactory())
                       .register("https",
                                 sslConnectionSocketFactory)
                       .build());

// Customize the connection pool

CloseableHttpClient httpClient = HttpClientBuilder.create()
                                                  .setConnectionManager(poolingHttpClientConnectionManager)
                                                  .build()

没有自定义HttpClientConnectionManager：

SSLConnectionSocketFactory sslConnectionSocketFactory = 
    new SSLConnectionSocketFactory(SSLContexts.createDefault(),          
                                   new String[] { "TLSv1.2" },                                            
                                   null, 
           SSLConnectionSocketFactory.getDefaultHostnameVerifier());

CloseableHttpClient httpClient = HttpClientBuilder.create()
                                                  .setSSLSocketFactory(sslConnectionSocketFactory)
                                                  .build()
