Generating a Certificate Signing Request (CSR) using
OpenSSL

如何產生CSR

CSR是一個裡面包含有您的公鑰認證資訊的檔案,產生您的CSR並且將之複製並貼上到我們線上申請流程的CSR欄位:

To generate a pair of private key and public Certificate Signing Request (CSR) for a webserver, "server", use the following commands:

openssl req –new –nodes -keyout myserver.key –out server.csr

This creates a two files. The file myserver.key contains a private key; do not disclose this file to anyone. Carefully protect the private key.

In particular, be sure to backup the private key, as there is no means to recover it should it be lost. The private key is used as input in the command to generate a Certificate Signing Request (CSR).

You will now be asked to enter details to be entered into your CSR
.
What you are about to enter is what is called a Distinguished Name or a DN.

For some fields there will be a default value, If you enter '.', the field will be left blank.

-----
Country Name (2 letter code) [AU]: GB
State or Province Name (full name) [Some-State]: Yorks
Locality Name (eg, city) []: York
Organization Name (eg, company) [Internet Widgits Pty Ltd]: MyCompany Ltd
Organizational Unit Name (eg, section) []: IT
Common Name (eg, YOUR name) []: mysubdomain.mydomain.com
Email Address []:

Please enter the following 'extra' attributes to be sent with your certificate request

A challenge password []:
An optional company name []:
-----

Use the name of the webserver as Common Name (CN). If the domain name is mydomain.com append the domain to the hostname (use the fully qualified domain name).

The fields email address, optional company name and challenge password can be left blank for a webserver certificate.

 

產生完CSR後

CSR產生完成後,請使用一般文字編輯軟體如記事本(note pad)將 server.csr 開啟,並將全部內容複製並貼至我們線上申請流程裡的CSR欄位,我們將會為您作線上的CSR格式測試,並開始作憑證內容與證明文件的審核。
