Android MQTT客户端使用SSL/TLS连接MQTT代理服务器

1. mosquitto 安装到windows 上，我使用windows作为mosquitto代理服务器

 2. 安装openssl

3.生成服务器证书

 openssl req -new -x509 -days 3650 -keyout m2mqtt_ca.key -out m2mqtt_ca.crt

openssl genrsa -des3 -out m2mqtt_srv.key 1024

openssl req -out m2mqtt_srv.csr -key m2mqtt_srv.key -new

openssl x509 -req -in m2mqtt_srv.csr -CA m2mqtt_ca.crt -CAkey m2mqtt_ca.key -CAcreateserial -out m2mqtt_srv.crt -days 3650

android仅支持BKS格式的证书 ，使用keytool装换CRT成为BKS格式，

4.生成BKS格式证书

先下载bcprov-jdk16-141.jar 放到1.6.0.jdk/Contents/Home/lib/ext目录下

keytool -importcert -keystore test.bks -file m2mqtt_ca.crt  -storetype BKS -provider org.bouncycastle.jce.provider.BouncyCastleProvider

5.配置服务器端

修改 mosquitto_m2mqtt.conf

• bind_address : server name (in my case bind_address ppatierno-PC);

• port : MQTT port for SSL/TLS is 8883 (port 8883);

• cafile : path for CA certificate (cafile C:\OpenSSL-Win64\bin\PEM\m2mqtt_ca.crt);

• certfile : path for server certificate (certfile C:\OpenSSL-Win64\bin\PEM\m2mqtt_srv.crt);

• keyfile : path server private key (keyfile C:\OpenSSL-Win64\bin\PEM\m2mqtt_srv.key);

• tls_version : TLS version (tls_version tlsv1);

启动服务器

mosquitto –c mosquitto_m2mqtt.conf –v

6.android客户端，添加信任证书代码

SSLContext context;

     KeyStore ts = KeyStore.getInstance("BKS");

     ts.load(getResources().openRawResource(R.raw.test),

       "123456".toCharArray());

     TrustManagerFactory tmf = TrustManagerFactory

       .getInstance("X509");

     tmf.init(ts);

     TrustManager[] tm = tmf.getTrustManagers();

     context = SSLContext.getInstance("TLS");

     context.init(null, tm, null);

     // SocketFactory factory= SSLSocketFactory.getDefault();

     // Socket socket =factory.createSocket("localhost", 10000);

     SocketFactory factory = context.getSocketFactory();

     conOpt.setSocketFactory(factory);
