在Android设备上使用NanoHttpd创建HTTPS服务器

androidsslhttpswssnanohttpd
11

我正在尝试使用NanoHttpd在Android设备上运行HTTPS服务器（我的最终目标是在Android上运行WSS服务器）。我已经成功地在Android上使用NanoHttpd运行了HTTP服务器和WebSocket。我使用以下命令在Mac上生成密钥，并将其复制到我的设备上：

keytool -genkey -keystore key.keystore -storepass keypass -storetype BKS -provider org.bouncycastle.jce.provider.BouncyCastleProvider

我编写了以下代码：

keyStore = KeyStore.getInstance("BKS");
keyStore.load(stream, keyStorePwd.toCharArray());
keyManagerFactory = KeyManagerFactory
           .getInstance(KeyManagerFactory.getDefaultAlgorithm());
keyManagerFactory.init(keyStore, keyStorePwd.toCharArray());
SSLContext sc = SSLContext.getInstance("TLS");
sc.init(keyManagerFactory.getKeyManagers(), null, null);
server.makeSecure(sc.getServerSocketFactory());
server.start();

我在Chrome 38和42上测试了启用了“Minimum SSL/TLS”标志的“SSLv3”。但当我想连接服务器时，我一直收到“ERR_SSL_VERSION_OR_CIPHER_MISMATCH”错误。

我尝试了不同的协议实例（SSL/TLS），在多台机器和浏览器上进行了尝试。我尝试了NanoHttpd SSLServerSocketFactory方法，但是错误仍然存在。

我已经查看了一些示例，包括： https://github.com/NanoHttpd/nanohttpd/issues/139

有人对此有任何评论吗？

经过几个小时的辛勤劳作，我终于搞定了！

这是我的（可用的）代码：

// I placed this block right below my class declaration so it runs
// as soon as the class is defined. (this is for localhost testing ONLY!!!!)    
static {
    //for localhost testing only
    javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier(
    new javax.net.ssl.HostnameVerifier(){

        public boolean verify(String hostname,
                javax.net.ssl.SSLSession sslSession) {
            if (hostname.equals("localhost")) {
                return true;
            }
            return false;
        }
    });
}

// then in an init function, I set it all up here
this.secureAppServer = new NanoHTTPD(9043);
File f =new File("src/main/resources/key001.jks");
System.setProperty("javax.net.ssl.trustStore", f.getAbsolutePath());
this.secureAppServer.setServerSocketFactory(new SecureServerSocketFactory(NanoHTTPD.makeSSLSocketFactory("/" +f.getName(), "myawesomepassword".toCharArray()), null));

this.secureAppServer.start();

这里是实际的NanoHttpd测试用例，它精确地说明了如何使用Nano风格完成。

注意：Nano尝试将密钥库作为资源流加载，因此KeyStore必须驻留在src/main/resources中（这就是我将其设置为硬路径的原因）。看起来这是一个安全特性 ;)。 - Decoded

注意不要公开发布你的密码。 - Denys Vitali

什么？src/main/resources/key001.jks在构建时是有效的，但在运行时无效。 - Jeffrey Blattman

谢谢你的提醒 @DenysVitali，幸运的是这些不是真正的生产密码 ;)，只是为了测试目的。 - Decoded
@JeffreyBlattman，你是否对Java安装进行了任何更改（例如关于安全JAR文件的更改），并且是否已正确安装了您的证书在您的rooted Android设备上？ - Decoded

其他答案对我没有用。我必须使用KeyStore Explorer创建一个BKS-V1密钥库，并将其保存到Android资产文件夹中，命名为“ keystore.bks”。或者，您也可以使用以下代码创建KeyStore文件，然后仅打开它并将其类型更改为BKS-V1，使用KeyStore Explorer。
keytool -genkey -keyalg RSA -alias selfsigned -keystore keystore.bks -storepass myKeyStorePass -validity 360 -keysize 2048 -ext SAN=DNS:localhost,IP:127.0.0.1  -validity 9999

我使用了下面的代码使其工作。
package com.example.myappname

import java.io.IOException;
import java.io.InputStream;
import java.security.KeyStore;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.UnrecoverableKeyException;
import java.security.cert.CertificateException;

import javax.net.ssl.KeyManagerFactory;

import fi.iki.elonen.NanoHTTPD;

public class Server extends NanoHTTPD {
    public Server(int port) throws IOException, KeyStoreException, CertificateException, NoSuchAlgorithmException, UnrecoverableKeyException {
        super(port);
        KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
        InputStream keyStoreStream = context.get().getAssets().open("keystore.bks");
        keyStore.load(keyStoreStream, "myKeyStorePass".toCharArray());
        KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
        keyManagerFactory.init(keyStore, "myCertificatePass".toCharArray());
        makeSecure(NanoHTTPD.makeSSLSocketFactory(keyStore, keyManagerFactory), null);
    }

    @Override
    public Response serve(IHTTPSession session) {
    }
}

只需编写以下代码，您的Android设备就可以运行HTTPS服务器。

Server server = new Server(8080);
server.start(NanoHTTPD.SOCKET_READ_TIMEOUT, false);

这段代码得益于以下Github问题评论中提供的示例。 https://github.com/NanoHttpd/nanohttpd/issues/535#issuecomment-479269044
Ravi Patel，我使用这个来创建https服务器，但是当我从Web应用程序中请求表单时，我遇到了握手失败的问题，因为Web应用程序没有客户端证书，只有单向认证。我们如何只使用服务器端证书实现https？ - wasim
@wasim 你可以尝试在客户端禁用证书验证。这可能会解决问题。 - Ravi Patel
客户端Web应用程序服务器证书已经验证。因此，我们只有服务器证书。这是因为我使用的证书是自签名的吗？ - wasim
是的，如果您正在使用自签名证书，这种情况可能会发生。 - Ravi Patel
@RaviPatel 当我将密钥类型更改为BKS-V1时，它可以工作。但是我遇到了另一个问题：javax.net.ssl.SSLHandshakeException: 握手失败 at com.android.org.conscrypt.ConscryptFileDescriptorSocket.startHandshake(ConscryptFileDescriptorSocket.java:286) 请问你能告诉我如何解决吗？ - kollein

由于我无法使用 JKS 类型的密钥库，因此对 Decoded 的解决方案进行了修改。

相反，我使用 Keystore Explorer 生成了一个 BKS 密钥。选择 BKS-V1 作为新 KeyStore 的类型，然后在启动之前设置 NanoHTTPD 服务器：

androidWebServer = new AndroidWebServer(port);

File f = new File("src/main/resources/localkey.bks");
System.setProperty("javax.net.ssl.trustStore", f.getAbsolutePath());
androidWebServer.setServerSocketFactory(new AndroidWebServer.SecureServerSocketFactory(AndroidWebServer.makeSSLSocketFactory("/" + f.getName(), "yourKeyStorePass".toCharArray()), null));

androidWebServer.start();

此链接有解决方案：https://www.baeldung.com/nanohttpd#https 使用keytool生成jks。
keytool -genkey -keyalg RSA -alias selfsigned
  -keystore keystore.jks -storepass your_password -validity 360
  -keysize 2048 -ext SAN=DNS:localhost,IP:127.0.0.1  -validity 9999

将keystore.jks移动到项目src/main/resources中

并使用以下代码：

public class HttpsExample  extends NanoHTTPD {
 
    public HttpsExample() throws IOException {
        super(8080);
        makeSecure(NanoHTTPD.makeSSLSocketFactory(
          "/keystore.jks", "password".toCharArray()), null);
        start(NanoHTTPD.SOCKET_READ_TIMEOUT, false);
    }
 
    // main and serve methods
}
