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.

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

All SSL Certificates require a private key to work. The private key is a separate file that’s used in the encryption/decryption of data sent between your server and the connecting clients. A private key is created by you—the certificate owner—when you request your certificate with a Certificate Signing.

  1. How to generate private key and CSR from command line. This article describes how to generate a private key and CSR (Certificate Signing Request) from the command line. You may need to do this if you want to obtain an SSL certificate for a system that does not include cPanel access, such as a dedicated server or unmanaged VPS.
  2. Jul 08, 2009  In this article, let us review how to generate private key file (server.key), certificate signing request file (server.csr) and webserver certificate file (server.crt) that can be used on Apache server with modssl. Key, CSR and CRT File Naming Convention.

Note:Replace “server ” with the domain name you intend to secure.

3. Enter your CSR details

Enter the following CSR details when prompted:

  • 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. /letasoft-sound-booster-key-generator.html.

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.

Generate a certificate signing request

Before you can install a Secure Socket Layer (SSL) certificate, you must first generate a certificate signing request (CSR). You can do this by using one of the following methods:

OpenSSL

The following sections describe how to use OpenSSL to generate a CSR for a single host name. If you want to generate a CSR for multiple host names, we recommend using the Cloud Control Panel or the MyRackspace Portal.

Install OpenSSL

Check whether OpenSSL is installed by using the following command:

  • CentOS® and Red Hat® Enterprise Linux®

    The following output provides an example of what the command returns:

  • Debian® and the Ubuntu® operating system

    The following output provides an example of what the command returns:
