三阳藻、簡(jiǎn)述

??本文主要講述SSLSocket的簡(jiǎn)單使用方式。

四谈撒、詳情

??SSLSocket是Socekt的加密通訊模式腥泥。本文介紹無(wú)證書(shū)實(shí)現(xiàn)SSLSocket的方式。
??第一：重寫(xiě)X509TrustManager啃匿，使信任所有證書(shū)蛔外。如下代碼：

package com.test.sys.plcd.util;

import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

import javax.net.ssl.X509TrustManager;

/**
 * 創(chuàng)建人: lipy
 * 創(chuàng)建時(shí)間: 2018/4/23
 * 修改人:lipy
 * 修改時(shí)間:2018/4/23
 * 修改內(nèi)容:
 *
 * 功能描述: 信任所有證書(shū)
 */
public class MyX509TrustManager implements X509TrustManager {

    public MyX509TrustManager() throws Exception {

    }

    /*
     * Delegate to the default trust manager.
     */
    public void checkClientTrusted(X509Certificate[] chain, String authType)
            throws CertificateException {

    }

    /*
     * Delegate to the default trust manager.
     */
    public void checkServerTrusted(X509Certificate[] chain, String authType)
            throws CertificateException {

    }

    /*
     * Merely pass this through.
     */
    public X509Certificate[] getAcceptedIssuers() {
//      return new java.security.cert.X509Certificate[0];
        return null;
    }
}

??第二：創(chuàng)建SSLSocket蛆楞。如下代碼：

//java
import java.io.IOException;
import java.net.UnknownHostException;

import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSocket;
import javax.net.ssl.TrustManager;

try {
    TrustManager[] tm = new TrustManager[]{new MyX509TrustManager()};
    SSLContext sslContext = SSLContext.getInstance("SSLv3");
    sslContext.init(null, tm, new java.security.SecureRandom());

    SSLSocket sslSocket = sslContext.getSocketFactory().createSocket(mHost, mPort);

} catch (UnknownHostException e) {
} catch (IOException e) {
} catch (Exception e) {
}

//kotlin
import java.io.IOException;
import java.net.UnknownHostException;

import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSocket;
import javax.net.ssl.TrustManager;

try {
      val tm = arrayOf<TrustManager>(MyX509TrustManager())
      val sslContext = SSLContext.getInstance("SSLv3")
      sslContext.init(null, tm, java.security.SecureRandom())

      val mSllSocket = sslContext.socketFactory.createSocket(mHost, mPort) as SSLSocket?
  
} catch (e: UnknownHostException) {
} catch (e: IOException) {
} catch (e: Exception) {
}
