阅读此文首先需要具备数据加解密,公钥,私钥,签名,证书等基础知识。

通信服务端:使用tomcat

通信客户端:使用apache httpclient 4.5.1

1. 服务端操作

1.
keytool -genkey -v -alias tomcat -keyalg RSA -keystore D:\servesert\tomcat.keystore -validity 36500
终端问答的参数:
CN=helloworld.com, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=Unknown
keypassword 123456 storepassword 123456

这步生成服务端的私钥和证书。 keystore是一个秘钥和证书的容器,里面可以装多个秘钥和证书。alias是一个keystore里证书或秘钥的唯一的识别id。CN=helloworld.com是服务端的域名,做测试时,客户端机器需要配置helloworld.com的hosts。

keytool -list -v -keystore D:\servesert\tomcat.keystore 
查看该keystore里的证书和私钥。
keytool
-keystore D:\servesert\tomcat.keystore -export -alias tomcat -file D:\servesert\tomcat.cer
将tomcat.keystore这个秘钥库里alias为tomcat的公钥导出为证书,这个证书将添加到客户端的受信任秘钥库中。

2.客户端操作

keytool -genkey -v -alias me -keyalg RSA -keystore D:\cert\me.keystore -validity 36500
CN=hello, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=Unknown
keypassword 123456 storepassword 123456
生成客户端秘钥,CN名字可以随便填

keytool -import -v -alias tomcat -file D:\servesert\tomcat.cer -keystore D:\cert\trust.keystore
将服务端导出的证书添加到客户端受信任的秘钥库中。

keytool
-list -v -keystore D:\cert\me.keystore
keytool
-list -v -keystore D:\cert\trust.keystore

keytool
-keystore D:\cert\me.keystore -export -alias me -file D:\cert\me.cer 将客户端私钥库中的客户端证书导出,之后会添加到服务端的受信任证书库。

3.服务端操作

keytool -import -v -alias me -file D:\cert\me.cer -keystore D:\servecert\trust.keystore
将客户端的证书导入服务器的受信任证书库

4.tomcat server.xml配置

 <Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol"
               maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
               clientAuth="true" sslProtocol="TLS" keystoreFile="D:\\servesert\\tomcat.keystore" 
               keystorePass="123456" truststoreFile="D:\\servesert\\trust.keystore" 
               truststorePass="123456" /> 

5.java客户端代码

package com.xy;

import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.conn.ssl.TrustSelfSignedStrategy;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import org.apache.http.ssl.SSLContexts;


import javax.net.ssl.SSLContext;
import java.io.File;
import java.io.IOException;
import java.security.KeyManagementException;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.UnrecoverableKeyException;
import java.security.cert.CertificateException;

public class Test {
    public static void main(String[] args) throws IOException, CertificateException, NoSuchAlgorithmException, KeyStoreException, KeyManagementException, UnrecoverableKeyException {
        // Trust own CA and all self-signed certs
        SSLContext sslcontext = SSLContexts.custom()
                .loadTrustMaterial(new File("D:\\cert\\trust.keystore"), "123456".toCharArray(),
                        new TrustSelfSignedStrategy())
                .loadKeyMaterial(new File("D:\\cert\\me.keystore"), "123456".toCharArray(), "123456".toCharArray()).build();
        // Allow TLSv1 protocol only
        SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
                sslcontext,
                new String[] { "TLSv1" },
                null,
                SSLConnectionSocketFactory.getDefaultHostnameVerifier());
        CloseableHttpClient httpclient = HttpClients.custom()
                .setSSLSocketFactory(sslsf)
                .build();

        try {

            HttpGet httpget = new HttpGet("https://helloworld.com:8443/hello/testget.json");

            System.out.println("Executing request " + httpget.getRequestLine());

            CloseableHttpResponse response = httpclient.execute(httpget);
            try {
                HttpEntity entity = response.getEntity();

                System.out.println("----------------------------------------");
                System.out.println(response.getStatusLine());
                System.out.println(EntityUtils.toString(entity));

                EntityUtils.consume(entity);
            } finally {
                response.close();
            }
        } finally {
            httpclient.close();
        }
    }

//        HttpPost httpPost = new HttpPost("http://targethost/login");
//        List  nvps = new ArrayList ();
//        nvps.add(new BasicNameValuePair("username", "vip"));
//        nvps.add(new BasicNameValuePair("password", "secret"));
//        httpPost.setEntity(new UrlEncodedFormEntity(nvps));
//        CloseableHttpResponse response2 = httpclient.execute(httpPost);
//
//        try {
//            System.out.println(response2.getStatusLine());
//            HttpEntity entity2 = response2.getEntity();
//            // do something useful with the response body
//            // and ensure it is fully consumed
//            EntityUtils.consume(entity2);
//        } finally {
//            response2.close();
//        }
}

说明:如果自己的私钥库中有超过一个可选证书,系统会默认选择第一个。若受信任证书库中有超过一个证书,会遍历证书直到找到第一个匹配的。
