This article provides step-by-step instructions for generating a Certificate Signing Request (CSR) in OpenSSL. This is most commonly required for web servers such as Apache HTTP Server and NGINX.

Switch to a working directory
To generate a CSR in Apache OpenSSL, you can check the Steps below.
GNU/Linux & Mac OS X users:
Open a terminal and browse to a folder where you would like to generate your keypair
Navigate to your OpenSSL “bin” directory and open a command prompt in the same location.
Generate a CSR & Private Key:
openssl req -out CSR.csr -new -newkey rsa:2048 -keyout privatekey.key
To generate a 4096-bit CSR you can replace the rsa:2048 syntax with rsa:4096 as shown below.
openssl req -out CSR.csr -new -newkey rsa:4096 -keyout privatekey.key
Note: You will be prompted to enter a password in order to proceed. Keep this password as you will need it to use the Certificate.
Fill out the following fields as prompted:
Note: The following characters can not be accepted: < > ~ ! @ # $ % ^ * / \ ( ) ?.,&
You should now have a Private Key (privatekey.key) which should stay on your computer, and a Certificate Signing Request (CSR.csr), which can be submitted to GlobalSign to sign your public key. Each of these files can be viewed in a plain text editor such as Notepad, TextEdit, Vi, Nano, and Notepad++.
