本篇的主要内容为Java证书体系的实现。
请大家在阅读本篇内容时先阅读 Java加密技术(四),预先了解RSA加密算法。
在构建Java代码实现前,我们需要完成证书的制作。
1.生成keyStroe文件
在命令行下执行以下命令:
- keytool -genkey -validity 36000 -alias www.zlex.org -keyalg RSA -keystore d:\zlex.keystore
keytool -genkey -validity 36000 -alias www.zlex.org -keyalg RSA -keystore d:\zlex.keystore
其中
-genkey表示生成密钥
-validity指定证书有效期,这里是
36000天
-alias指定别名,这里是
www.zlex.org
-keyalg指定算法,这里是
RSA
-keystore指定存储位置,这里是
d:\zlex.keystore
在这里我使用的密码为
123456
控制台输出:
- 输入keystore密码:
- 再次输入新密码:
- 您的名字与姓氏是什么?
- [Unknown]: www.zlex.org
- 您的组织单位名称是什么?
- [Unknown]: zlex
- 您的组织名称是什么?
- [Unknown]: zlex
- 您所在的城市或区域名称是什么?
- [Unknown]: BJ
- 您所在的州或省份名称是什么?
- [Unknown]: BJ
- 该单位的两字母国家代码是什么
- [Unknown]: CN
- CN=www.zlex.org, OU=zlex, O=zlex, L=BJ, ST=BJ, C=CN 正确吗?
- [否]: Y
- 输入<tomcat>的主密码
- (如果和 keystore 密码相同,按回车):
- 再次输入新密码:
输入keystore密码: 再次输入新密码: 您的名字与姓氏是什么? [Unknown]: www.zlex.org 您的组织单位名称是什么? [Unknown]: zlex 您的组织名称是什么? [Unknown]: zlex 您所在的城市或区域名称是什么? [Unknown]: BJ 您所在的州或省份名称是什么? [Unknown]: BJ 该单位的两字母国家代码是什么 [Unknown]: CN CN=www.zlex.org, OU=zlex, O=zlex, L=BJ, ST=BJ, C=CN 正确吗? [否]: Y 输入<tomcat>的主密码 (如果和 keystore 密码相同,按回车): 再次输入新密码:
这时,在D盘下会生成一个zlex.keystore的文件。
2.生成自签名证书
光有keyStore文件是不够的,还需要证书文件,证书才是直接提供给外界使用的公钥凭证。
导出证书:
- keytool -export -keystore d:\zlex.keystore -alias www.zlex.org -file d:\zlex.cer -rfc
keytool -export -keystore d:\zlex.keystore -alias www.zlex.org -file d:\zlex.cer -rfc
其中
-export指定为导出操作
-keystore指定
keystore文件
-alias指定导出
keystore文件中的别名
-file指向
导出路径
-rfc以文本格式输出,也就是以
BASE64编码输出
这里的密码是
123456
控制台输出:
- 输入keystore密码:
- 保存在文件中的认证 <d:\zlex.cer>
输入keystore密码: 保存在文件中的认证 <d:\zlex.cer>
当然,使用方是需要导入证书的!
可以通过自签名证书完成CAS单点登录系统的构建!
Ok,准备工作完成,开始Java实现!
通过java代码实现如下:

由此完成了证书验证体系!
同样,我们可以对代码做签名——代码签名!
通过工具JarSigner可以完成代码签名。
这里我们对tools.jar做代码签名,命令如下:
- jarsigner -storetype jks -keystore zlex.keystore -verbose tools.jar www.zlex.org
jarsigner -storetype jks -keystore zlex.keystore -verbose tools.jar www.zlex.org
控制台输出:
- 输入密钥库的口令短语:

- 正在更新: META-INF/WWW_ZLEX.RSA
- 正在签名: org/zlex/security/Security.class
- 正在签名: org/zlex/tool/Main$1.class
- 正在签名: org/zlex/tool/Main$2.class
- 正在签名: org/zlex/tool/Main.class
- 警告:

代码签名认证的用途主要是对发布的软件做验证,支持 Sun Java .jar (Java Applet) 文件(J2SE)和 J2ME MIDlet Suite 文件。
