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.
Extracting the public certificate from the pfx file

2. Generate Pfx From Cert And Private Key
3. Private Key Definition

Intune supports the use of private and public key pair (PKCS) certificates. This article can help you configure the required infrastructure like on-premises certificate connectors, export a PKCS certificate, and then add the certificate to an Intune device configuration profile. Microsoft Intune. A.pfx file is a PKCS#12 archive: a file that can contain a lot of objects with optional password protection; but, usually, a PKCS#12 archive has a certificate (possibly with its assorted set of CA certificates) attached to it and the corresponding private key. How can I find the private key for my SSL certificate. If you just got an issued SSL certificate and are having a hard time finding the corresponding private key, this article can help you to find that one and only key for your certificate.

/keygeneration-function-in-bods.html. Enter in the password for the PFX file when asked. 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).

Generate Pfx From Cert And Private Key

: First you will need a linux based operating system that supports openssl command to run the following commands.

Private Key Definition

1. Extract the key-pair
   #openssl pkcs12 -in sample.pfx -nocerts -nodes -out sample.key

2. Get the Private Key from the key-pair
   #openssl rsa -in sample.key -out sample_private.key

3. Get the Public Key from key pair
   #openssl rsa -in sample.key -pubout -out sample_public.key

4. Generate ssh key for sourcetree. Need to do some modification to the private key -> to pkcs8 format
   #openssl pkcs8 -topk8 -inform PEM -in sample_private.key -outform PEM -nocrypt
   Copy the output and save it as sample_private_pkcs8.key

5. Get those files
   public key: sample_public.key
   private key: sample_private_pkcs8.key
