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.
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.
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
Where Is Your Private Key? On Windows servers, the OS manages your certificate files for you in a hidden folder, but you can retrieve the private key by exporting a “.pfx” file that contains the certificate(s) and private key. Open Microsoft Management Console (MMC). Dec 04, 2017 Below is the steps used for the scenario requested. Select Current Type = PEM. Change for = PFX. Upload your certificate. Upload your private key. If you have ROOT CA cert or intermediate certs upload them too. Set a password of your choosing, used in IIS. Click the reCaptcha to prove you’re not a bot.
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.
To decrypt something using RSA private key you treat your ciphertext as a number and raise it to the power of d modulus n: plaintext = ( ciphertext^d ) mod n To generate private (d,n) key using openssl you can use the following command: openssl genrsa -out private.pem 1024. Create rsa public key.
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.
KeyGen is a shortened word for Key Generator. The word 'keygen' means a small program that can generate a cd key, activation number, license code, serial number, or registration number for a piece of software. A keygen is made available through crack groups free to download. Empire total war code cd key. When writing a keygen, the author will identify the algorithm used in creating a valid cd key.
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.
Import PFX Certificate into Microsoft Windows Server and Configure it
To import your certificate to your server using the DigiCert Certificate Utility, you need to follow the instructions for that particular server type:
| IIS 10 | Exchange 2013 |
| IIS 8 | Exchange 2010 |
| IIS 7 | Exchange 2007 |
| IIS 6 |
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
Pfx Export Key
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.
