需要原型工具：

OpenSSL下载地址：http://slproweb.com/products/Win32OpenSSL.html, _(*3)

• 安装OpenSSL, _(*4)

  • 随意安装到哪里

• 点击OpenSLL的bin目录下的 openssl.exe 进行私钥和公钥的生成, _(*5)

  1. 生成私钥
  • genrsa -out rsa_private_key.pem 1024
  1. 生成公钥
  • rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem

• 将生产的私钥、公钥拷贝到你的PHP项目中, _(*6)

• 开启PHP的OpenSSL扩展, _(*7)

1. 将php.ini中的extension=php_openssl.dll开启（去掉;）
