Android 4.4.2 SSL 握手中止

【中文标题】Android 4.4.2 SSL 握手中止【英文标题】：Android 4.4.2 SSL handshake aborted 【发布时间】：2016-04-02 07:00:11 【问题描述】：代码适用于我的 Genymotion android 4.4.4 模拟器，但不适用于我正在使用的设备 (4.4.2)。
我尝试了很多“信任所有证书”的解决方法，但都无济于事（我认为这不是问题，因为证书是 AOK）。
我想我已经识别了密码（使用我桌面上的 wireshark 跟踪）； TLS 0x00 0x1E 这似乎有点少见？
知道如何解决吗？
这是我的代码
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
CloseableHttpClient client = HttpClientBuilder.create().setSSLSocketFactory(sslsf).build();
String baseURL = "https://mysite.co.uk/api/";
HttpGetHC4 request = new HttpGetHC4(baseURL + "/authenticate?user=abcd&password=1234");
CloseableHttpResponse response = client.execute(request);
还有错误；

尝试使用不同的技术/库；
RequestQueue queue = Volley.newRequestQueue(this);
String url ="https://mysite.co.uk/api/authenticate?user=abcd&password=1234";
// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>()
@Override
public void onResponse(String response)
// Display the first 500 characters of the response string.
Log.d("response: ", response);
, new Response.ErrorListener()
@Override
public void onErrorResponse(VolleyError error)
Log.d("response: ", error.toString());
);
// Add the request to the RequestQueue.
queue.add(stringRequest);
返回；
D/response:: com.android.volley.NoConnectionError: javax.net.ssl.SSLHandshakeException: javax.net.ssl.SSLProtocolException: SSL handshake aborted: ssl=0x6ad51be0: Failure in SSL library, usually a protocol error

或者使用来自Javax.net.ssl.SSLHandshakeException: javax.net.ssl.SSLProtocolException: SSL handshake aborted: Failure in SSL library, usually a protocol error 的 NoSSLv3SocketFactory hack；
HttpStack stack = new HurlStack(null, new NoSSLv3SocketFactory());
RequestQueue queue = Volley.newRequestQueue(this, stack);
返回；

【问题讨论】：
我猜你搜索了很多问题，但你看到了吗？：***.com/questions/29916962/… 我做到了，但是我似乎无法弄清楚如何将 NoSSLv3SocketFactory 应用于 CloseableHttpClient。如果我尝试类似SSLSocketFactory nosslv3 = new NoSSLv3SocketFactory(sslc.getSocketFactory()); CloseableHttpClient client = HttpClientBuilder.create().setSSLSocketFactory(nosslv3).build(); 我会得到setSSLSocketFactory (org.apache.http.conn.socket.LayeredConnectionSocketFactory in HttpClientBuilder cannot be applied to javax.net.ssl.SSLSocketFactory
0x00,0x1E 是 TLS_KRB5_WITH_DES_CBC_SHA 并且确实非常罕见而且非常不安全。我怀疑这个密码是否适用于 Android 4.4.4。相反，我会假设服务器名称指示存在问题，但只有在对目标站点了解得更多的情况下才能说得更多。检查SSLLabs 以了解与特定 Android 版本相关的问题或该网站是否需要 SNI。
插入该站点并没有返回任何我可以看到的奇怪内容。似乎支持 TLS 1.0、TLS 1.1 和 TLS 1.2。在握手模拟下，它建议使用 TLS 1.2 w/ciper；安卓 4.4.2 的 TLS_RSA_WITH_RC4_128_SHA？
我现在被引导相信设备不支持站点支持的任何密码。为java找到一种明确声明这一点的方法会很棒吗？在我工作的那一刻，我不得不创建一个 http->https apache 代理
【参考方案1】：
Android 使用不同的协议进行网络操作。
不同安卓版本的默认配置。
我找到了 OkHttpClient 的解决方案。
Protocol Supported (API Levels) Enabled by default (API Levels)
SSLv3 1–25 1–22
TLSv1 1+ 1+
TLSv1.1 16+ 20+
TLSv1.2 16+ 20+
所以我们必须在 Android VERSION >= 16 & VERSION
创建java文件Tls12SocketFactory.java
/**
* Enables TLS v1.2 when creating SSLSockets.
* <p/>
* For some reason, android supports TLS v1.2 from API 16, but enables it by
* default only from API 20.
* @link https://developer.android.com/reference/javax/net/ssl/SSLSocket.html
* @see SSLSocketFactory
*/
public class Tls12SocketFactory extends SSLSocketFactory
private static final String[] TLS_V12_ONLY = "TLSv1.2";
final SSLSocketFactory delegate;
public Tls12SocketFactory(SSLSocketFactory base)
this.delegate = base;
@Override
public String[] getDefaultCipherSuites()
return delegate.getDefaultCipherSuites();
@Override
public String[] getSupportedCipherSuites()
return delegate.getSupportedCipherSuites();
@Override
public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException
return patch(delegate.createSocket(s, host, port, autoClose));
@Override
public Socket createSocket(String host, int port) throws IOException, UnknownHostException
return patch(delegate.createSocket(host, port));
@Override
public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException
return patch(delegate.createSocket(host, port, localHost, localPort));
@Override
public Socket createSocket(InetAddress host, int port) throws IOException
return patch(delegate.createSocket(host, port));
@Override
public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException
return patch(delegate.createSocket(address, port, localAddress, localPort));
private Socket patch(Socket s)
if (s instanceof SSLSocket)
((SSLSocket) s).setEnabledProtocols(TLS_V12_ONLY);
return s;
将此方法放在代码中的某个位置。
public static OkHttpClient.Builder enableTls12OnPreLollipop(OkHttpClient.Builder client)
if (Build.VERSION.SDK_INT >= 16 && Build.VERSION.SDK_INT < 22)
try
SSLContext sc = SSLContext.getInstance("TLSv1.2");
sc.init(null, null, null);
client.sslSocketFactory(new Tls12SocketFactory(sc.getSocketFactory()));
ConnectionSpec cs = new ConnectionSpec.Builder(ConnectionSpec.MODERN_TLS)
.tlsVersions(TlsVersion.TLS_1_2).build();
List<ConnectionSpec> specs = new ArrayList<>();
specs.add(cs);
specs.add(ConnectionSpec.COMPATIBLE_TLS);
specs.add(ConnectionSpec.CLEARTEXT);
client.connectionSpecs(specs);
catch (Exception exc)
Log.e("OkHttpTLSCompat", "Error while setting TLS 1.2", exc);
return client;
public OkHttpClient getNewHttpClient()
OkHttpClient.Builder client = new OkHttpClient.Builder().followRedirects(true).followSslRedirects(true)
.retryOnConnectionFailure(true).cache(null).connectTimeout(5, TimeUnit.SECONDS)
.writeTimeout(5, TimeUnit.SECONDS).readTimeout(5, TimeUnit.SECONDS);
return enableTls12OnPreLollipop(client).build();
如下创建 OkHttp 实例：
private OkHttpClient getNewHttpClient()
OkHttpClient.Builder client = new OkHttpClient.Builder()
.followRedirects(true)
.followSslRedirects(true)
.retryOnConnectionFailure(true)
.cache(null)
.connectTimeout(5, TimeUnit.SECONDS)
.writeTimeout(5, TimeUnit.SECONDS)
.readTimeout(5, TimeUnit.SECONDS);
return enableTls12OnPreLollipop(client).build();
像这样使用客户端对象：
OkHttpClient client = getNewHttpClient();
Request.Builder requestBuilder = new Request.Builder();
URL url = new URL("YOUR_URL_LINK");
Request request = requestBuilder.url(url).build();
Call call = client.newCall(request);
Response response = call.execute();
THANKS

【参考方案2】：试试这个：
public class ClientSSLSocketFactory
public static SSLSocketFactory getSocketFactory(Context context)
try
X509TrustManager tm = new X509TrustManager()
public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException
public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException
public X509Certificate[] getAcceptedIssuers()
return new X509Certificate[0];
;
SSLContext ctx = SSLContext.getInstance("TLS");
ctx.init(null, new TrustManager[]tm, new SecureRandom());
SSLSocketFactory ssf = SSLCertificateSocketFactory.getDefault(10000, new SSLSessionCache(context));
return ssf;
catch (Exception ex)
Log.e("ssl", "Error during the getSocketFactory");
ex.printStackTrace();
return null;
在创建队列时：
sRequestQueue = Volley.newRequestQueue(context, new HurlStack(null, ClientSSLSocketFactory.getSocketFactory()));
希望对你有帮助。

【参考方案3】：我认为问题在于基于此类字符串的 SSL v3，这表明它正在尝试使用 SSL v3: SSL23_GET_SERVER_HELLO:sslv3
SSL v3 被认为是不安全的，因此在大多数现代软件上都被禁用（即使在您原本期望它可以工作的地方，许多公司也只是简单地将其移除）。我还从堆栈跟踪中看到代码使用了 apache http 客户端： org.apache.http.impl.client
所以你必须以某种方式阻止 apache http 客户端使用 ssl v3。 Apache http 客户端与标准 Java SSL/TLS 库分开存在。
还有一个没有收到答案的 *** 问题： How do disable SSLv3 in Apache HttpClient
这个链接看起来最有希望： https://discretemkt.wordpress.com/2014/11/16/commons-httpclient-can-disable-sslv3/
在那里，关键线是
Protocol.registerProtocol(scheme, customHttps);
该调用似乎允许您绕过现有的 ssl 工厂。如果您先运行该代码，它可能会工作，假设 apache http 客户端版本是兼容的。
另请注意，如今 TLS 1.0 也被认为是不安全的。 TLS 1.2 和 1.3 以及现在的标准。
