openssl req -new -newkey rsa:2048 -nodes -keyout yourdomain.key -out yourdomain.csr

Replace yourdomain with the domain name you’re securing. For example, if your domain name is coolexample.com, you would type coolexample.key and coolexample.csr.

Open the CSR in a text editor and copy all of the text.
