Remember to back up the Private Key. If the key is lost, you can no longer use the issued certificate. 1. Log in to the server via SSH (or a PC with OpenSSL installed). 2. Run the following command to generate a private key and CSR. ```bash openssl req -out CSR.csr -new -newkey rsa:2048 -nodes -keyout PrivateKey.key (you can replace CSR.csr with .csr and PrivateKey.key can be replaced with .key) ``` 3. In the command line, fill out the form. Example: | | | |---|---| | Country Name (2 letter code) | NO | | State or Province Name (full name) | OSLO | | Locality Name (eg, city) | OSLO | | Organization Name (eg, company) | Servetheworld | | Organizational Unit Name (eg, section) | HQ | | Common Name (eg, fully qualified host name) | [www.servetheworld.net](http://www.servetheworld.net) or servetheworld.net (*\*.demo.no* for a Wildcard certificate) | | Email Address | | 4. The CSR and private key files should now be created. 5. You can now use your newly created CSR when ordering an SSL certificate at #### Create a CSR on Windows Server and IIS (Internet Information Services) 1. Log in as **Administrator** on the Windows Server 2. Select Start, Run (or Windows key + R), enter **inetmgr** and run it. 3. Click the server name under **Connections**, then double-click **Server Certificates** | | | |---|---| | [![](https://faq.servetheworld.net/myserve/images/2/a/7/1/0/2a7106c70dd312735d92c7c24a608781630f326b-for-windows-1.png)](https://faq.servetheworld.net/myserve/images/3/3/c/8/0/33c80f6aa459866e429736fe5c7bccd77c8fb7c8-for-windows-1.png) | [![](https://faq.servetheworld.net/myserve/images/d/6/c/3/9/d6c3991b4a4e46dd615dbeba29f768ef012d0807-for-windows-2.png)](https://faq.servetheworld.net/myserve/images/0/6/d/e/7/06de79ea289dc53e84faf4af44d62e8464adb252-for-windows-2.png) | 4.
