If you want to convert your website from HTTP to HTTPS, you need to get a SSL certificate from a valid organization like Verisign or Thawte. Sims 3 generations product key. 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 mod_ssl.

  • SiteGround uses key-based authentication for SSH. This has proven more secure over standard username/password authentication. More information on SSH keys can be found here. You can generate an SSH key pair directly in cPanel, or you can generate the keys yourself and just upload the public one in cPanel to use with your hosting account.
  • Aug 01, 2014 This tutorial provides an approach on how to set up Secure Sockets Layer (SSL) communication cryptographic protocol on Apache Web Server installed in Red Hat Enterprise Linux/CentOS 7.0, and generate self-signed Certificates and Keys with the help of a bash script which greatly simplifies the entire process. Step 1: Install and Configure Apache.
  • This is typically used to generate a test certificate or a self signed root CA.newkey arg this option creates a new certificate request and a new private key. The argument takes one of several forms. Rsa:nbits, where nbits is the number of bits, generates an RSA key nbits in size.
  • If you have your own private key and CA-signed certificate files, before importing the keystores to your VMware Cloud Director environment, you must create keystore files in which to import the certificates and the private keys for both the HTTPS and the console proxy service.
  • Nov 21, 2019  How to Generate a SSL/TLS Certificate Signing Request (CSR) on Debian 10. For any live website, SSL Certificates have become a key requirement. A Certificate Authority (CA) verifies and issue SSL certificates. There are two categories of these certificates.

Key, CSR and CRT File Naming Convention

I typically like to name the files with the domain name of the HTTPS URL that will be using this certificate. 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.

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.
