+欢迎使用微信支付!
+附件中的三份文件(证书pkcs12格式、证书pem格式、证书密钥pem格式),为接口中强制要求时需携带的证书文件。
+证书属于敏感信息,请妥善保管不要泄露和被他人复制。
+不同开发语言下的证书格式不同,以下为说明指引:
+    证书pkcs12格式(apiclient_cert.p12)
+        包含了私钥信息的证书文件,为p12(pfx)格式,由微信支付签发给您用来标识和界定您的身份
+        部分安全性要求较高的API需要使用该证书来确认您的调用身份
+        windows上可以直接双击导入系统,导入过程中会提示输入证书密码,证书密码默认为您的商户号(如:1900006031)
+    证书pem格式(apiclient_cert.pem)
+        从apiclient_cert.p12中导出证书部分的文件,为pem格式,请妥善保管不要泄漏和被他人复制
+        部分开发语言和环境,不能直接使用p12文件,而需要使用pem,所以为了方便您使用,已为您直接提供
+        您也可以使用openssl命令来自己导出:openssl pkcs12 -clcerts -nokeys -in apiclient_cert.p12 -out apiclient_cert.pem
+    证书密钥pem格式(apiclient_key.pem)
+        从apiclient_cert.p12中导出密钥部分的文件,为pem格式
+        部分开发语言和环境,不能直接使用p12文件,而需要使用pem,所以为了方便您使用,已为您直接提供
+        您也可以使用openssl命令来自己导出:openssl pkcs12 -nocerts -in apiclient_cert.p12 -out apiclient_key.pem
+备注说明:  
+        由于绝大部分操作系统已内置了微信支付服务器证书的根CA证书,  2018年3月6日后, 不再提供CA证书文件(rootca.pem)下载
