Generate Crt And Key File From Pfx
How to convert a PFX to a seperate.key/.crt file In this article will show you the commands you need to convert your.PFX Certificate file to a seperate certificate and keyfile. This article can come in handy when you need to import your certificates on devices like Cisco routers/loadbalancers etc. Where you probably need to import the certificates and keyfiles in plain text (unencrypted). Feb 22, 2019 How to create a single PFX file containing a private key from a separate.cer/.crt file and.key file. Cause: Sometimes certificate files and private keys are supplied as distinct files but IIS and Windows requires certificates with private keys to be in a single PFX file. Follow the procedure below to extract separate certificate and private key files from the.pfx file. Take the file you exported (e.g. Certname.pfx) and copy it to a system where you have OpenSSL installed. Note: the.pfx file is in PKCS#12 format and includes both the certificate and the private key. May 13, 2014 Neither of these can simply be completed within IIS and installed. There is a way to use these files to create a personal information exchange file (.pfx) which can then be imported into IIS. This walkthrough will provide the information necessary to combine the.crt and.key files into a usable.pfx file.

Exporting Your SSL Certificate from a Microsoft Server for Importing to Another Microsoft Server
Background
Windows servers use .pfx files that contain the public key file (SSL certificate file) and the associated private key file. DigiCert provides your SSL certificate file (public key file). You use your server to generate the associated private key file as part of the CSR.
It's possible to extract the public keys using keytool, check this.Export/import commands We'll use the keytool -export command toextract the public key into a file, and then use the keytool -importcommand to insert it into a new keystore.
You need both the public and private keys for an SSL certificate to function. So, if you need to transfer your SSL certificates from one server to another, you need to export is as a .pfx file.
Export Prerequisite
To create a .pfx file, the SSL certificate and its corresponding private key must be on the same computer/workstation. You may need to import the certificate to the computer that has the associated private key stored on it. (e.g., the laptop/desktop computer where you created the CSR) before you can successfully export it as a .pfx file.
For help importing the certificate, see SSL Certificate Importing Instructions: DigiCert Certificate Utility.
How to Export Your SSL Certificate w/Private Key Using the DigiCert Certificate Utility
These instructions explain how to export an installed SSL certificate from a Microsoft server and its corresponding private key as a .pfx file for importing to another server. If you need your SSL Certificate in Apache .key format, please see Export a Windows SSL Certificate to an Apache Server (PEM Format).
On your Windows Server, download and save the DigiCert® Certificate Utility for Windows executable (DigiCertUtil.exe).
Run the DigiCert® Certificate Utility for Windows (double-click DigiCertUtil).
In the DigiCert Certificate Utility for Windows©, click SSL (gold lock), select the certificate that you want to export as a .pfx file, and then click Export Certificate.
In the Certificate Export wizard, select Yes, export the private key, select pfx file, and then check Include all certificates in the certification path if possible, and finally, click Next.
A .pfx file uses the same format as a .p12 or PKCS12 file.
Note: If the Yes, export the private key option is grayed out (not unusable), the certificate's matching private key is not on that computer. This prevents you from being able to create the .pfx certificate file. To fix this problem, you will need to import the certificate to the same machine where the certificate's CSR was created. See Export Prerequisite.
In the Password and Confirm Password boxes, enter and confirm your password, and then, click Next.
Note: This password is used when you import this SSL certificate onto other Windows type servers or other servers or devices that accept a .pfx file.
In the File name box, click … to browse for and select the location and file name where you want to save the .pfx file, provide a file name (i.e. mySSLCertificate), click Save, and then, click Finish.
After you receive the 'Your certificate and key have been successfully exported' message, click OK.

Troubleshooting
After importing your certificate on to the new server, if you run into certificate errors, try repairing your certificate trust errors using DigiCert® Certificate Utility for Windows. If this does not fix the errors, contact support.
Test Your Installation
To verify that the installation is correct, use our DigiCert® SSL Installation Diagnostics Tool and enter the DNS name of the site (e.g., www.yourdomain.com, or mail.yourdomain.com) that you are securing to test your SSL certificate.
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.
