A CSR (Certificate Signing Request) is a file containing server and company information. The file is submitted to a Certificate Authority to obtain an SSL certificate.

What command generates a CSR on NGINX?

Use this command: openssl req -new -newkey rsa:2048 -nodes -keyout server.key -out server.csr

This creates both a private key (server.key) and CSR file (server.csr).

What information do I need to generate a CSR?

You need your organization’s name, location, domain name, and email address. The Common Name must match your website’s domain name exactly.

Store CSR files in the /etc/nginx/ssl/ directory. Create this directory if it doesn’t exist using: mkdir /etc/nginx/ssl/

How do I verify my CSR is correct?

Use the OpenSSL command: openssl req -text -noout -verify -in server.csr

This shows all CSR information and confirms its validity.

What is the standard key size for NGINX CSR?

The recommended key size is 2048 bits. This provides good security without impacting server performance significantly.
