Java加密技术(八)——数字证书
Posted onJava加密技术(八)——数字证书
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: Shell代码
- 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: Console代码
- 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
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
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: Shell代码
- 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: Console代码
- 输入keystore密码:
- 保存在文件中的认证
输入keystore密码:
保存在文件中的认证
