Apache HttpClient 4.3 和 x509 客户端证书进行身份验证

Question

现在我正在寻找有关如何通过 HttpComponentsMessageSender（不相关）重写客户端 x509 证书身份验证的已弃用解决方案的任务的解决方案。

例如，不推荐使用的解决方案是：

    SSLSocketFactory lSchemeSocketFactory = new SSLSocketFactory(this.keyStore, this.keyStorePassword);
    Scheme sch = new Scheme("https", 443, lSchemeSocketFactory);

    DefaultHttpClient httpClient = (DefaultHttpClient)getHttpClient();
    httpClient.getConnectionManager().getSchemeRegistry().register(sch);

作为我正在使用的 CloseableHttpClient 的新解决方案：

    SSLContextBuilder sslContextBuilder = SSLContexts.custom()
            // this key store must contain the key/cert of the client
            .loadKeyMaterial(keyStore, keyStorePassword.toCharArray());

    if (trustStore != null) {
        // this key store must contain the certs needed and trusted to verify the servers cert
        sslContextBuilder.loadTrustMaterial(trustStore);
    }

    SSLContext sslContext = sslContextBuilder.build();

    LayeredConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext);

    // Create a registry of custom connection socket factories for supported
    // protocol schemes / https
    Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory>create()
            .register("https", sslsf)
            .register("http", new PlainConnectionSocketFactory())
            .build();

    PoolingHttpClientConnectionManager connPoolControl =
            new PoolingHttpClientConnectionManager(socketFactoryRegistry);
    setConnPoolControl(connPoolControl);
    getClientBuilder().setSSLSocketFactory(sslsf);

我仍然收到来自服务器的 403 禁止。但是，当我使用“已弃用”版本的解决方案时，效果很好。 SSL 证书已签署 Thawte。

有什么想法吗？ 谢谢

Tomas，也许为时已晚，但我希望它能帮助其他人...... 有一种方法，我用它来使用 Apache HttpClient 4.3 创建 CloseableHttpClient：

public static CloseableHttpClient prepareClient() {
    try {           
        SSLContext sslContext = SSLContexts.custom().loadTrustMaterial(null, new TrustSelfSignedStrategy()).useTLS().build();
        HttpClientBuilder builder = HttpClientBuilder.create();
        SSLConnectionSocketFactory sslConnectionFactory = new SSLConnectionSocketFactory(sslContext, SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
        builder.setSSLSocketFactory(sslConnectionFactory);
        Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
                .register("https", sslConnectionFactory)
                .register("http", new PlainConnectionSocketFactory())
                .build();
        HttpClientConnectionManager ccm = new BasicHttpClientConnectionManager(registry);
        builder.setConnectionManager(ccm);
        return builder.build();
    } catch (Exception ex) {

        return null;
    }
}

Apache 基金会从 4.4 版本开始将 org.apache.http.conn.ssl.SSLContextBuilder、org.apache.http.conn.ssl.SSLContexts 和 org.apache.http.conn.ssl.SSLSocketFactory 移至弃用，@987654321 @您可以找到 Apache Client 4.5.2 API 弃用列表。因此，可以像这样更改 pervious 方法：

public static CloseableHttpClient prepareClient() {
    try {
        SSLContext sslContext = SSLContexts.custom()
                .loadTrustMaterial(null, new TrustSelfSignedStrategy()).build();
        HttpClientBuilder builder = HttpClientBuilder.create();
        SSLConnectionSocketFactory sslConnectionFactory = 
                new SSLConnectionSocketFactory(sslContext.getSocketFactory(), 
                        new NoopHostnameVerifier());
        builder.setSSLSocketFactory(sslConnectionFactory);
        Registry<ConnectionSocketFactory> registry = 
                RegistryBuilder.<ConnectionSocketFactory>create()
                .register("https", sslConnectionFactory)
                .register("http", new PlainConnectionSocketFactory())
                .build();
        HttpClientConnectionManager ccm = new BasicHttpClientConnectionManager(registry);
        builder.setConnectionManager(ccm);
        return builder.build();
    } catch (Exception ex) {
        LOG.error("couldn't create httpClient!! {}", ex.getMessage(), ex);
        return null;
    }
}

NoopHostnameVerifier

NO_OP HostnameVerifier 本质上是主机名验证 离开。此实现是无操作的，并且从不抛出 SSL 异常。

如果你需要验证主机名，你可以使用 DefaultHostnameVerifier 或者你可以实现你的自定义主机名验证器。

您需要创建一个包含受信任 CA 的密钥库，即trust.jks。在此密钥库中，您应该只放置应用程序将要连接的服务器的证书。

然后，您需要一个用于服务器身份的密钥库，即identity.jks。在此密钥库中，您应该将私钥 + 证书 + CA 链存储在一个别名（名称）下，您的应用程序将使用该别名向服务器进行身份验证。

然后你可以像这样构建HttpClient：

public static HttpClient getHttpClient() throws KeyStoreException, CertificateException, NoSuchAlgorithmException, IOException, UnrecoverableKeyException, KeyManagementException {

    KeyStore identityKeyStore = KeyStore.getInstance("jks");
    identityKeyStore.load(MyClass.class.getClassLoader().getResourceAsStream("identity.jks"), "identity_password".toCharArray());

    KeyStore trustKeyStore = KeyStore.getInstance("jks");
    trustKeyStore.load(MyClass.class.getClassLoader().getResourceAsStream("trust.jks"), "trust_password".toCharArray());

    SSLContext sslContext = SSLContexts
            .custom()
            // load identity keystore
            .loadKeyMaterial(identityKeyStore, "identity_password".toCharArray(), new PrivateKeyStrategy() {
                @Override
                public String chooseAlias(Map<String, PrivateKeyDetails> aliases, Socket socket) {
                    return "identity_alias";
                }
            })
            // load trust keystore
            .loadTrustMaterial(trustKeyStore, null)
            .build();

    SSLConnectionSocketFactory sslConnectionSocketFactory = new SSLConnectionSocketFactory(sslContext,
            new String[]{"TLSv1.2", "TLSv1.1"},
            null,
            SSLConnectionSocketFactory.getDefaultHostnameVerifier());

    return HttpClients.custom()
            .setSSLSocketFactory(sslConnectionSocketFactory)
            .build();
}

要构建identity.jks，需要CAs链、公钥和私钥：

$1 = mycustomidentity

# make the keycert bundle for pkcs12 keystore
cat intermediate/certs/ca-chain.cert.pem \
    intermediate/certs/$1.cert.pem \
    intermediate/private/$1.key.pem \
    > intermediate/keycerts/$1.full-chain.keycert.pem

# generate the pkcs12 keystore with the alias of the server url
openssl pkcs12 -export \
    -in intermediate/keycerts/$1.full-chain.keycert.pem \
    -out intermediate/pkcs12s/$1.full-chain.p12 \
    -name $1 \
    -noiter -nomaciter

# .p12 to .jks
keytool -importkeystore -srckeystore $1.full-chain.p12 \
    -srcstoretype pkcs12 -srcalias $1 \
    -destkeystore identity.jks -deststoretype jks \
    -deststorepass identity_password -destalias identity_alias

trust.jks文件只需要服务器的证书（见https://stackoverflow.com/a/36427118/2692914或https://stackoverflow.com/a/7886248/2692914），改别名没有问题：

# .crt, .cer into a .jks
keytool -import -alias trust_alias -file server_certificate.crt \
    -keystore trust.jks

以下是 HttpClient 4.4+ 的代码（更新了 @Daniyar 4.4+ 的代码）

import org.apache.http.config.Registry;
import org.apache.http.config.RegistryBuilder;
import org.apache.http.conn.socket.ConnectionSocketFactory;
import org.apache.http.conn.socket.PlainConnectionSocketFactory;
import org.apache.http.conn.ssl.DefaultHostnameVerifier;
import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.conn.ssl.TrustSelfSignedStrategy;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.impl.conn.PoolingHttpClientConnectionManager;
import org.apache.http.ssl.SSLContexts;

public static CloseableHttpClient createApacheHttp4ClientWithClientCertAuth() {
    try {
        SSLContext sslContext = SSLContexts
                .custom()
                .loadTrustMaterial(null, new TrustSelfSignedStrategy())
                .build();

        SSLConnectionSocketFactory sslConnectionFactory = new SSLConnectionSocketFactory(sslContext,
                new DefaultHostnameVerifier());

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

        HttpClientBuilder builder = HttpClientBuilder.create();
        builder.setSSLSocketFactory(sslConnectionFactory);
        builder.setConnectionManager(new PoolingHttpClientConnectionManager(registry));

        return builder.build();
    } catch (Exception ex) {

        return null;
    }
}
