Jul 08, 2009 You can also generate self signed SSL certificate for testing purpose. 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. $ openssl req -new -key /path/to/wwwservercom.key -out /path/to/wwwservercom.csr. This will fire up OpenSSL, instruct it to generate a certificate signing request, and let it know to use a key we are going to specify – the one we just created, in fact. It will automatically generate your CSR (Certificate Signing Request) and your Private Key, based on the information which you will introduce in the CSR form below. You will need the CSR code when applying for an SSL Certificate under your SSL Dragon account. Create a CSR (Certificate Signing Request) General CSR Creation Guidelines Before you can order an SSL certificate, it is recommended that you generate a Certificate Signing Request (CSR. This guide will walk you through the steps to create a Certificate Signing Request, (CSR for short.) SSL certificates are the industry-standard means of securing web traffic to and from your server, and the first step to getting your own SSL is to generate a CSR. This guide is written specifically for CentOS 7. Log onto your server using SSH. 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 Request (CSR).

SSL Certificates fall into two broad categories: 1) Self-Signed Certificate which is an identity certificate that is signed by the same entity whose identity it certifies-on signed with its own private key, and 2) Certificates that are signed by a CA (Certificate Authority) such as Let’s Encrypt, Comodo and many other companies.

Self-Signed Certificates are commonly used in test environments for LAN services or applications. /terminal-generate-ssh-key-kinsta.html. They can be generated for free using OpenSSL or any related tool. On the other hand, for sensitive, public-facing production services, applications or websites, it is highly recommended to use a certificate issued and verified by a trusted CA.

The first step towards acquiring an SSL certificate issued and verified by a CA is generating a CSR (short for Certificate Signing Request).

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

To create a CSR, you need the OpenSSL command line utility installed on your system, otherwise, run the following command to install it.

Then issue the following command to generate a CSR and the key that will protect your certificate.

where:

req enables the part of OpenSSL that handles certificate requests signing.
-newkey rsa:2048 creates a 2048-bit RSA key.
-nodes means “don’t encrypt the key”.
-keyout example.com.key specifies the filename to write on the created private key.
-out example.com.csr specifies the filename to write the CSR to.

Answer correctly, the questions you will be asked. Note that your answers should match information in legal documents regarding the registration of your company. This information is critically checked by the CA before issuing your certificate.

After creating your CSR, view the contents of the file using a cat utility, select it and copy it.

Copy CSR Key

Then go back to your CA’s website, log in, go to the page will contain the SSL certificate you purchased, and activate it. Then in a window such as the one below, paste your CSR in the correct input field.

In this example, we created a CSR for a multiple domain certificate purchased from Namecheap.

Then follow the rest of the instructions to initiate activation of your SSL certificate. For more information about OpenSSL command, see its man page: Cs go key generator 2015.
