环境

• MacOS 10.14.6
• JDK1.8

生成私钥公钥

• 使用JDK自带的keytool工具生成签名

  keytool -genkeypair -keysize 1024 -validity 3650 -alias "zuiyuPrivateKey" -keypass "zuiyu_private_password_1234" -keystore "zuiyuPrivateKeys.keystore" -storepass "zuiyu_public_password_1234" -dname "CN=zuiyu,OU=zuiyu,O=zuiyu,L=BJ,ST=BJ,C=CN"
  

• 导出签名文件 zuiyuCertfile.cer

  keytool -exportcert -alias "zuiyuPrivateKey" -keystore "zuiyuPrivateKeys.keystore" -storepass "zuiyu_public_password_1234" -file "zuiyuCertfile.cer"
  

• 导入签名文件

  keytool -import -alias "zuiyuPublicCert" -file "zuiyuCertfile.cer" -keystore "zuiyuPublicCerts.keystore" -storepass "zuiyu_public_password_1234"
  

• 帮助命令（根据需要食用）

  # 删除
  keytool -delete -alias zuiyuPrivateKey -keystore "zuiyuPrivateKeys.keystore" -storepass "zuiyu_public_password_1234"
  
  # 查看
  keytool -list -v -keystore zuiyuPrivateKeys.keystore -storepass "zuiyu_public_password_1234"
  

• 最后

  上述命令执行完成之后，会在当前路径下生成三个文件，分别是：zuiyuPrivateKeys.keystore、zuiyuPublicCerts.keystore、zuiyuCertfile.cer。其中文件zuiyuCertfile.cer不再需要可以删除，文件zuiyuPrivateKeys.keystore用于当前的license-server项目给客户生成license文件，而文件zuiyuPublicCerts.keystore则随应用代码部署到客户服务器，用户解密license文件并校验其许可信息。
