How to Generate Your CSR (SSL Certificate Signing Request)

To generate a CSR you will need access to a UNIX terminal on a machine with OpenSSL installed, or an equivalent: 

https://docs.gandi.net/en/ssl/common_operations/csr.html

 Or use csrgenerator.com online for example.

Common Name: Provide the domain name you are wanting to secure. For more details see the previous section on this page.

Once you are finished executing this command, you will have two files: a public .csr file, and a private .key file that absolutely must be kept secret. 

The private key is generated at the same time as your CSR, and will be stored on your computer or server. Only you, therefore, have access to that file, which ends in ”.key” .

You can open the file by right clicking on the .csr file and choosing to open it with a text editor. 

Then, copy and paste the entire contents of the CSR including the parts

"-----BEGIN CERTIFICATE REQUEST-----"

and

"-----END CERTIFICATE REQUEST-----".
