The following instructions will guide you through the CSR generation process on Nginx (OpenSSL). To learn more about CSRs and the importance of your private key, reference our Overview of Certificate Signing Request article. If you already generated the CSR and received your trusted SSL certificate, reference our SSL Installation Instructions and disregard the steps below.

Sep 17, 2019 CSR (Certificate Signing Request) is an encoded text that contains the domain name and contact details of domain ownership. When you think of creating CSR on Node.js– an open source cross-platform runtime environment, which is used to create server-side web app, you need OpenSSL. Ah, in fact it is strictly the same format than the files generated with openssl. I just use to generate always 4096 and I did not expect apple to use 2048 only. So to generate a set of keys for ios developer: openssl genrsa -out ios-dev.key 2048 openssl req -new -key ios-dev.key -out ios-dev.csr. To generate a CSR using OpenSSL run:% openssl req -new -nodes -out host.csr You will be prompted for the contents of the certificate subject (country, state, organization, etc). The only critical piece is the common name, this needs to be set to the FQDN of your host. The CSR is in the file host.csr and the key for this request is in privkey.pem. If the system says there is a mismatch, then you need to double check the CSR and Private Key which you generated, and which came together. You need to make sure that you used that specific CSR when you configured your SSL Certificate. When the SSL Certificate is issued, you need to use the Private Key that pairs with that specific CSR. Friendly Tip: You can generate a CSR on a server, which isn't a problem if you know what you’re doing. For the average customer though, this guide will help and simplify the whole process. Don't hesitate to call or live chat with our SSL experts.
1. Log in to your server’s terminal.
You will want to log in via Secure Shell (SSH).
2. Enter CSR and Private Key command
Generate a private key and CSR by running the following command:
Here is the plain text version to copy and paste into your terminal:
Note:Replace “server ” with the domain name you intend to secure.
3. Enter your CSR details
Enter the following CSR details when prompted: Os x generate public ssh key.
- Common Name: The FQDN (fully-qualified domain name) you want to secure with the certificate such as www.google.com, secure.website.org, *.domain.net, etc.
- Organization: The full legal name of your organization including the corporate identifier.
- Organization Unit (OU): Your department such as ‘Information Technology’ or ‘Website Security.’
- City or Locality: The locality or city where your organization is legally incorporated. Do not abbreviate.
- State or Province: The state or province where your organization is legally incorporated. Do not abbreviate.
- Country: The official two-letter country code (i.e. US, CH) where your organization is legally incorporated.
Note: You are not required to enter a password or passphrase. This optional field is for applying additional security to your key pair.
4. Generate the order
Locate and open the newly created CSR in a text editor such as Notepad and copy all the text including:
Note 1: Your CSR should be saved in the same user directory that you SSH into unless otherwise specified by you.

Note 2: We recommend saving or backing up your newly generate “.key ” file as this will be required later during the installation process.
Return to the Generation Form on our website and paste the entire CSR into the blank text box and continue with completing the generation process.

Upon generating your CSR, your order will enter the validation process with the issuing Certificate Authority (CA) and require the certificate requester to complete some form of validation depending on the certificate purchased. For information regarding the different levels of the validation process and how to satisfy the industry requirements, reference our validation articles.
After you complete the validation process and receive the trusted SSL Certificate from the issuing Certificate Authority (CA), proceed with the next step using our SSL Installation Instructions for Nginx using OpenSSL.
