How to Generate a Self-Signed Certificate and Private Key using OpenSSL Generating a private key and self-signed certificate can be accomplished in a few simple steps using OpenSSL. We provide here detailed instructions on how to create a private key and self-signed certificate valid for 365 days.
During SSL setup, if you’re on a Windows-based system, there may be times when you need to generate your Certificate Signing Request (CSR) and Private key outside the Windows keystore. This may be useful, for example, if you want to backup your SSL Certificate or import it to multiple servers.
May 22, 2019 A Certificate Signing Request (CSR) is the first step in setting up an SSL Certificate on your website. SSL certificates are provided by Certificate Authorities (CA), which require a Certificate Signing Request (CSR). This guide will instruct you on how to generate a Certificate Signing Request using OpenSSL.
Reasons for importing keys include wanting to make a backup of a private key (generated keys are non-exportable, for security reasons), or if the private key is provided by an external source. This document will guide you through using the OpenSSL command line tool to generate a key pair which you can then import into a YubiKey.

Jan 18, 2015 Generate private key and certificate signing request. A private key and certificate signing request are required to create an SSL certificate. These can be generated with a few simple commands. When the openssl req command asks for a “challenge password”, just press return, leaving the password empty.

Key, CSR and CRT File Naming Convention

Starcraft 2 heart of the swarm serial key generator. I typically like to name the files with the domain name of the HTTPS URL that will be using this certificate. Vmware esxi 6.7 license key generator. This makes it easier to identify and maintain.

Instead of server.key, I use www.thegeekstuff.com.key
Instead of server.csr, I use www.thegeekstuff.com.csr
Instead of server.crt, I use www.thegeekstuff.com.crt

1. Generate Private Key on the Server Running Apache + mod_ssl

First, generate a private key on the Linux server that runs Apache webserver using openssl command as shown below.

The generated private key looks like the following.

2. Generate a Certificate Signing Request (CSR)

Using the key generate above, you should generate a certificate request file (csr) using openssl as shown below.

3. Generate a Self-Signed SSL Certificate

For testing purpose, you can generate a self-signed SSL certificate that is valid for 1 year using openssl command as shown below.

You can use this method to generate Apache SSL Key, CSR and CRT file in most of the Linux, Unix systems including Ubuntu, Debian, CentOS, Fedora and Red Hat.

4. Get a Valid Trial SSL Certificate (Optional)

Instead of signing it youself, you can also generate a valid trial SSL certificate from thawte. i.e Before spending the money on purchasing a certificate, you can also get a valid fully functional 21 day trial SSL certificates from Thawte. Once this valid certificate works, you can either decide to purchase it from Thawte or any other SSL signing organization.

This step is optional and not really required. For testing purpose, you can always use the self-signed certificate that was generated from the above step.

Go to Thwate trial certificate request page and do the following:

Select “SSL Web Server Certificate (All servers)” under the “select your trial certificate”.
Do not check the PKCS #7 check-box under the “configure certificate”
Copy/Paste the *.csr file that you generate above in the textbox under “certificate signing request (CSR)”
Click on next at the bottom, which will give you a 21-day free trial certificate.

Copy/Paste the trial certificate to the www.thegeekstuff.com.crt file as shown below.
