SSL Basics: What is a Certificate Signing Request (CSR)?
For those of you who are new to SSL, or even you veterans who just want to brush up on your knowledge, we’re starting a series on SSL basics. First up are certificate signing requests (CSRs). These little files are a critical part of applying for an SSL Certificate, but what are they exactly and how can you generate one?
A certificate signing request (CSR) is one of the first steps towards getting your own SSL Certificate. Generated on the same server you plan to install the certificate on, the CSR contains information (e.g. common name, organization, country) the Certificate Authority (CA) will use to create your certificate. It also contains the public key that will be included in your certificate and is signed with the corresponding private key. We’ll go into more details on the roles of these keys below.
Jul 09, 2019 To sum up, ways to find your private key fully depend on the interface of the web server where you generate the CSR. If the methods described above did not help you find the private key for your certificate, the only solution would be to generate a new CSR/private key pair and reissue your certificate and to make sure that the key is saved on. 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.

In this article, we will demonstrate how to create a CSR (Certificate Signing Request) on a Linux system. Creating a CSR – Certificate Signing Request in Linux. Then issue the following command to generate a CSR and the key that will protect your.

The CA will use the data from the CSR to build your SSL Certificate. The key pieces of information include the following.
1. Information about your business and the website you’re trying to equip with SSL, including:
Common Name (CN) (e.g. *.example.com www.example.com mail.example.com) | The fully qualified domain name (FQDN) of your server. |
Organization (O) | The legal name of your organization. Do not abbreviate and include any suffixes, such as Inc., Corp., or LLC. For EV and OV SSL Certificates, this information is verified by the CA and included in the certificate. |
Organizational Unit (OU) | The division of your organization handling the certificate. |
City/Locality (L) | The city where your organization is located. This shouldn’t be abbreviated. |
State/County/Region (S) | The state/region where your organization is located. This shouldn't be abbreviated. |
Country (C) | The two-letter code for the country where your organization is located. |
Email Address | An email address used to contact your organization. |

2. The public key that will be included in the certificate. SSL uses public-key, or asymmetric, cryptography to encrypt transmitted data during an SSL session. The public key is used to encrypt and the corresponding private key is used to decrypt.
3. Information about the key type and length. The most common key size is RSA 2048, but some CAs support larger key sizes (e.g. RSA 4096+) or ECC keys.
The CSR itself is usually created in a Base-64 based PEM format. You can open the CSR file using a simple text editor and it will look like the sample below. You must include the header and footer (-----BEGIN NEW CERTIFICATE REQUEST-----) when pasting the CSR.
