Generate Private Key From Crt File Openssl
This guide will show you how to convert a .pfx certificate file into its separate public certificate and private key files. This can be useful if you want to export a certificate (in the pfx format) from a Windows server, and load it into Apache or Nginx for example, which requires a separate public certificate and private key file.
In the examples below, the following files will be used:
domain.name.pfx – This will be the PFX file containing the public certificate and private key.
domain.name.crt – This is the public certificate file outputted by OpenSSL.
domain.name.key – This is the private encryption key for the above certificate outputted by OpenSSL.

Enter in the password for the PFX file when asked. /donload-key-generated-in-google-ssh.html. You cant export the certificate or key if you don’t have this password.
You will now have the public certificate file (eg: domain.name.crt).
Extracting the private key from the pfx file
I have generated a.csr and.key file to send to dynadot (which sends that to AlphaSSL) with this command: openssl req -out foo.com.csr -new -newkey rsa:2048 -nodes -keyout foo.com.key It had asked me for confirmation and I received apparently an intermediate chain certificate, however I just placed it in foo.com.crt and it worked fine on my. 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.

You will now have the private key file (eg: domain.name.key).
