SSL双向认证Java实现 Tomcat篇

 

双向验证，在客户机连接服务器时，客户机验证服务器的证书，服务器验证客户机的证书，链接双方都要对彼此的数字证书进行验证，保证这是经过授权的才能够连接。

1. 生成服务器端的keystore和truststore文件：

    1.1. 以jks格式生成服务器端包含Public key和Private Key的keystore文件，keypass与storepass务必要一样，因为在tomcat server.xml中只配置一个password.
    keytool -genkey -alias server -keystore serverKeystore.jks -keypass 123456 -storepass 123456 -keyalg RSA  -keysize 512 -validity 365 -v -dname "CN = W03GCA01A,O = ABC BANK,DC = Server Https,DC = ABC,OU = Firefly Technology And Operation"

    1.2. 从keystore中导出别名为server的服务端证书.
    keytool -export -alias server -keystore serverKeystore.jks -storepass 123456 -file server.cer
 
    1.3. 将server.cer导入客户端的信任证书库clientTruststore.jks。 
     keytool -import -alias trustServer -file server.cer -keystore clientTruststore.jks -storepass 123456
 
2. 生成客户端的keystore和truststore文件：

    1.1. 以jks格式生成服务器端包含Public key和Private Key的keystore文件。
    keytool -genkey -alias client -keystore clientKeystore.jks -keypass 123456 -storepass 123456 -keyalg RSA  -keysize 512 -validity 365 -v -dname "CN = W03GCA01A,O = ABC BANK,DC = Client Https,DC = ABC,OU = Firefly Technology And Operation"

    1.2. 从keystore中导出别名为client的客户端证书.
    keytool -export -alias client -keystore clientKeystore.jks -storepass 123456 -file client.cer
 
    1.3. 将client.cer导入服务端的信任证书库serverTruststore.jks。 
     keytool -import -alias trustClient -file client.cer -keystore serverTruststore.jks -storepass 123456 
 
 
 服务器端： serverKeystore.jks   serverTruststore.jks
 客户端：   clientKeystore.jks   clientTruststore.jks
 
3. 在tomcat 配置server.xml

<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
               maxThreads="150" scheme="https" secure="true"
           clientAuth="true" sslProtocol="TLS"
           keystoreFile="keystore/serverKeystore.jks" keystorePass="123456"
        truststoreFile="keystore/serverTruststore.jks" truststorePass="123456" />

 

4. 客户端代码

package com.ssl.http;

import java.io.File;
import java.io.FileInputStream;
import java.security.KeyStore;
import java.security.KeyStoreException;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.conn.scheme.Scheme;
import org.apache.http.conn.ssl.SSLSocketFactory;
import org.apache.http.impl.client.DefaultHttpClient;

/**
 *
 * @author kevin

 */
public class ClientTwoWaySSL {

    /**
     * @param args
     * @throws Exception
     */
    public static void main(String[] args) throws Exception {
        // TODO Auto-generated method stub

        DefaultHttpClient httpclient = new DefaultHttpClient();

        KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
        KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());

        FileInputStream keyStoreIn = new FileInputStream(new File(
                "com/ssl/http/clientKeystore.jks"));
        FileInputStream trustStoreIn = new FileInputStream(new File(
                "com/ssl/http/clientTruststore.jks"));

        try {
            keyStore.load(keyStoreIn, "123456".toCharArray());
            trustStore.load(trustStoreIn, "123456".toCharArray());
        } finally {
            keyStoreIn.close();
            trustStoreIn.close();
        }

        SSLSocketFactory socketFactory = new SSLSocketFactory(keyStore,
                "123456", trustStore);
        Scheme sch = new Scheme("https", socketFactory, 8443);

        httpclient.getConnectionManager().getSchemeRegistry().register(sch);

        HttpGet httpget = new HttpGet("https://w03gca01a:8443/");

        System.out.println("Request:" + httpget.getRequestLine());

        HttpResponse response = httpclient.execute(httpget);
        HttpEntity entity = response.getEntity();

        System.out.println("----------------------------------------");
        System.out.println(response.getStatusLine());
        if (entity != null) {
            System.out.println("Response content length: "
                    + entity.getContentLength());
        }
        if (entity != null) {
            entity.consumeContent();
        }
        httpclient.getConnectionManager().shutdown();

    }

}

 

备注：

A. 如出现如下error，请配置C:\WINDOWS\system32\drivers\etc\hosts, 将“127.0.0.1     w03gca01a” 加在hosts文件中

# executing requestGET https://w03gca01a/ HTTP/1.1
# Exception in thread "main" javax.net.ssl.SSLException: hostname in certificate didn't match: <w03gca01a> != <localhost>
#     at org.apache.http.conn.ssl.AbstractVerifier.verify(AbstractVerifier.java:220)
#     at org.apache.http.conn.ssl.BrowserCompatHostnameVerifier.verify(BrowserCompatHostnameVerifier.java:54)
