1.License应用场景
在我们向客户销售商业软件的时候,常常需要对所发布的软件实行一系列管控措施,诸如验证使用者身份、软件是否到期,以及保存版权信息和开发商详情等。考虑到诸多应用场景可能处于离线环境,无法依赖网络进行实时认证,所以还需要考虑单机认证时的防破解问题。总之,License许可证利用HTTPS网站的证书和签名技术,一方面证明当前使用者是申请License的本人,另一方面要防止恶意破解,并伪造篡改License达到白嫖的目的。
为什么使用License授权?
License的作用是什么呢?收费软件的License其目的肯定是防止用户白嫖啦,所以License还应该具有以下一些功能:
- 授权使用: 明确用户需要满足的使用条件,如单用户、多用户、企业内部使用、全球使用等,并且通常会限定可安装和激活的设备数量。
- 期限控制: 规定软件的使用期限,可能是永久授权,也可能是订阅式授权,到期后用户需要续费才能继续使用。
- 限制功能: 根据不同等级的License,软件可以提供不同等级的功能,例如基础版、专业版、企业版等,License可以解锁相应版本的功能。
- 版权保护: 重申软件的知识产权归属,禁止未经授权的复制、分发、反编译、篡改或逆向工程等侵犯版权的行为。
- 法律保障: License作为法律合同,确立了软件提供商和用户之间的法律关系,明确了双方的权利和责任,如果发生违反协议的情况,软件提供商有权采取法律手段追究责任。
- 技术支持和升级服务:部分License中会规定用户是否有权享有免费的技术支持、软件更新和维护服务,以及这些服务的有效期限。
- 合规性要求: 对于特殊行业或特定地区,License可能还涉及到满足特定法规、标准或认证的要求。
归纳起来,我们可以总结出License的作用是:
- 控制软件使用者的使用权限
- 申明软件所有者的版权
- 规定软件的使用规范
2.证书准备
例如:私钥库密码为 priwd123456,公钥库密码为 pubwd123456,生成步骤如下:
# 1. 生成私钥库
# validity:私钥的有效期(天)
# alias:私钥别称
# keystore:私钥库文件名称(生成在当前目录)
# storepass:私钥库密码(获取 keystore 信息所需的密码,密钥库口令)
# keypass:别名条目的密码(密钥口令)
keytool -genkeypair -keysize 1024 -validity 3650 -alias "privateKey" -keystore "privateKeys.keystore" -storepass "pubwd123456" -keypass "priwd123456" -dname "CN=localhost, OU=localhost, O=localhost, L=SH, ST=SH, C=CN"
# 2. 把私钥库内的公钥导出到一个文件当中
# alias:私钥别称
# keystore:私钥库的名称(在当前目录查找)
# storepass:私钥库的密码
# file:证书名称
keytool -exportcert -alias "privateKey" -keystore "privateKeys.keystore" -storepass "pubwd123456" -file "certfile.cer"
# 3.再把这个证书文件导入到公钥库,certfile.cer 没用了可以删掉了
# alias:公钥名称
# file:证书名称
# keystore:公钥文件名称
# storepass:公钥库密码
keytool -import -alias "publicCert" -file "certfile.cer" -keystore "publicCerts.keystore" -storepass "pubwd123456"
3.代码工程
