凌阳教育是全国唯一“学员就业双100%品牌”，保证“学员100％就业”，保证“学员100％满意就业”。凌阳教育也是全国唯一“按班公布学员就业去向诚信机构”，每个班所有学员来自哪个学校就业后签约哪家企业都真实发布。截止2011年9月，凌阳教育学员已连续27期“双100％就业”。凌阳教育是全国唯一“原厂嵌入式培训机构”，以凌阳科技产业链企业的人才需求为契机，先后与2500多家企业建立学员就业合作关系。 |
Android的私钥和信任证书的格式必须是BKS格式的，通过配置本地JDK，让keytool可以生成BKS格式的私钥和信任证书,java本身没有BouncyCastle密库。
服务端：
Java代码
public class SSLServer {
private static final int SERVER_PORT = 50030;
private static final String SERVER_KEY_PASSWORD = "123456";
private static final String SERVER_AGREEMENT = "TLS";//使用协议
private static final String SERVER_KEY_MANAGER = "SunX509";//密钥管理器
private static final String SERVER_KEY_KEYSTORE = "JKS";//密库，这里用的是Java自带密库
private static final String SERVER_KEYSTORE_PATH = "src/data/kserver.keystore";//密库路径
private SSLServerSocket serverSocket;
public static void main(String[] args) {
SSLServer server = new SSLServer();
server.init();
server.start();
}
//由于该程序不是演示Socket监听，所以简单采用单线程形式，并且仅仅接受客户端的消息，并且返回客户端指定消息
public void start() {
if (serverSocket == null) {
System.out.println("ERROR");
return;
}
while (true) {
try {
System.out.println("Server Side......");
Socket s = serverSocket.accept();
InputStream input = s.getInputStream();
OutputStream utput = s.getOutputStream();
BufferedInputStream bis = new BufferedInputStream(input);
BufferedOutputStream bos = new BufferedOutputStream(output);
byte[] buffer = new byte[20];
bis.read(buffer);
System.out.println(new String(buffer));
bos.write("This is Server".getBytes());
bos.flush();
s.close();
} catch (Exception e) {
System.out.println(e);
}
}
}
public void init() {
try {
//取得SSLContext
SSLContext ctx = SSLContext.getInstance(SERVER_AGREEMENT);
//取得SunX509私钥管理器
KeyManagerFactory kmf = KeyManagerFactory.getInstance(SERVER_KEY_MANAGER);
//取得JKS密库实例
KeyStore ks = KeyStore.getInstance(SERVER_KEY_KEYSTORE);
//加载服务端私钥
ks.load(new FileInputStream(SERVER_KEYSTORE_PATH),
SERVER_KEY_PASSWORD.toCharArray());
//初始化
kmf.init(ks, SERVER_KEY_PASSWORD.toCharArray());
//初始化SSLContext
ctx.init(kmf.getKeyManagers(),null, null);
//通过SSLContext取得ServerSocketFactory，创建ServerSocket
serverSocket = (SSLServerSocket) ctx.getServerSocketFactory
().createServerSocket(SERVER_PORT);
} catch (Exception e) {
System.out.println(e);
}
}
}
客户端：
Java代码
public class MySSLSocket extends Activity {
private static final int SERVER_PORT = 50030;//端口号
private static final String SERVER_IP = "218.206.176.146";//连接IP
private static final String CLIENT_KET_PASSWORD = "123456";//私钥密码
private static final String CLIENT_TRUST_PASSWORD = "123456";//信任证书密码
private static final String CLIENT_AGREEMENT = "TLS";//使用协议
private static final String CLIENT_KEY_MANAGER = "X509";//密钥管理器
private static final String CLIENT_TRUST_MANAGER = "X509";//
private static final String CLIENT_KEY_KEYSTORE = "BKS";//密库，这里用的是BouncyCastle密库
private static final String CLIENT_TRUST_KEYSTORE = "BKS";//
private static final String ENCONDING = "utf-8";//字符集
