SSL单向认证Java实现 Tomcat篇

单向验证，客户机只验证服务器的证书，服务器不验证客户机的证书。所以只需要生成服务器端的keystore.

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"

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
 
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
 
 服务器端： serverKeystore.jks
 客户端：   clientTruststore.jks
 
4. 在tomcat 配置server.xml

Xml代码  

1. <Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"  
2.                  maxThreads="150" scheme="https" secure="true"  
3.              clientAuth="false" sslProtocol="TLS"   
4.              keystoreFile="keystore/serverKeystore.jks" keystorePass="123456"  />  

5. 客户端代码

Java代码  

1. /** 
2.  *  
3.  */  
4. package com.ssl.http;  
5.   
6. import java.io.File;  
7. import java.io.FileInputStream;  
8. import java.security.KeyStore;  
9.   
10. import org.apache.http.HttpEntity;  
11. import org.apache.http.HttpResponse;  
12. import org.apache.http.client.methods.HttpGet;  
13. import org.apache.http.conn.scheme.Scheme;  
14. import org.apache.http.conn.ssl.SSLSocketFactory;  
15. import org.apache.http.impl.client.DefaultHttpClient;  
16.   
17. /** 
18.  *  
19.  * @author kevin 
20.  * 
21.  */  
22. public class ClientOneWaySSL {  
23.   
24.     public final static void main(String[] args) throws Exception {  
25.         DefaultHttpClient httpclient = new DefaultHttpClient();  
26.   
27.         KeyStore trustStore  = KeyStore.getInstance(KeyStore.getDefaultType());          
28.         FileInputStream instream = new FileInputStream(new File("com/ssl/http/clientTruststore.jks"));   
29.         try {  
30.             trustStore.load(instream, "123456".toCharArray());  
31.         } finally {  
32.             instream.close();  
33.         }  
34.           
35.         SSLSocketFactory socketFactory = new SSLSocketFactory(trustStore);  
36.         Scheme sch = new Scheme("https", socketFactory, 8443);  
37.         httpclient.getConnectionManager().getSchemeRegistry().register(sch);  
38.   
39.         HttpGet httpget = new HttpGet("https://w03gca01a/");  
40.   
41.         System.out.println("executing request" + httpget.getRequestLine());  
42.           
43.         HttpResponse response = httpclient.execute(httpget);  
44.         HttpEntity entity = response.getEntity();  
45.   
46.         System.out.println("----------------------------------------");  
47.         System.out.println(response.getStatusLine());  
48.         if (entity != null) {  
49.             System.out.println("Response content length: " + entity.getContentLength());  
50.         }  
51.         if (entity != null) {  
52.             entity.consumeContent();  
53.         }  
54.   
55.         // When HttpClient instance is no longer needed,   
56.         // shut down the connection manager to ensure  
57.         // immediate deallocation of all system resources  
58.         httpclient.getConnectionManager().shutdown();          
59.     }  
60.   
61. }  

 

6. 运行成功打印如下：

Console代码  

1. executing requestGET https://w03gca01a/ HTTP/1.1  
2. ----------------------------------------  
3. HTTP/1.1 200 OK  
4. Response content length: 7347  

 

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

Exception代码  

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