Now we will start using OpenSSL to create the necessary keys and certificates. First generate the private/public RSA key pair: openssl genrsa -aes256 -out ca.key.pem 2048 chmod 400 ca.key.pem. This encodes the key file using an passphrase based on AES256. Then we need to create.
This guide will show you how to convert a .crt certificate file and associated private key, and convert it to a .pfx file using OpenSSL. This can be useful if you need to take a certificate file, and load it onto a Windows server for example.
A PFX file is a way of storing private keys, and certificates in a single encrypted file. It is commonly used to import and export certificates and keys on a Windows PC. In the example below, the following files will be used: domain.name.crt – this is the public certificate file. domain.name.key – This is the private encryption key for the above certificate. domain.name.pfx – This will be the PFX file outputted from OpenSSL. Converting the crt certificate and private key to a PFX file
This will create a pfx output file called “domain.name.pfx”.
You will be asked for the pass-phrase for the private key if needed, and also to set a pass-phrase for the newly created .pfx file too. You can now load this .pfx file onto a Windows machine, or wherever needed.

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. 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. 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.
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. Openssl Generate Key Crt Pair4. 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:
Copy/Paste the trial certificate to the www.thegeekstuff.com.crt file as shown below.
