Iis Generate New Private Key
All SSL Certificates require a private key to work. The private key is a separate file that’s used in the encryption/decryption of data sent between your server and the connecting clients. A private key is created by you—the certificate owner—when you request your certificate with a Certificate Signing Request (CSR). Jul 09, 2019 If the Private Key key file is lost, you’ll need to reissue your Certificate. Can I generate a new Private Key for my Certificate if I lose the old one? You can generate a new private key and CSR, or use the automatic CSR and key generation during Certificate reissue (this option is available for all Certificates except for the Multi.
- Dec 27, 2013 I am simply trying to apply a public cert to IIS server then export that cert with private as.pfx file, and it just isn't working! I generate the request via IIS, send the CSR to public CA (network solutions), they send me back the cert, I 'complete the request', but when I try to export the cert with private key, the option is NOT available and I don't understand why?
- Aug 18, 2015 This P7B can be used as the 'public key' in AccessData products. AD Enterprise, the AccessData Agent, and Site Server all require a public and private key pair to function. If you use IIS to generate or otherwise house your certificates, you may need to extract your private/public key pair to use with AccessData products.
- Here is an article form Siteground regarding managing private keys on their servers. Take a look at this article for more information on private key locations on common server platforms. If you can't locate your private key, you can generate a new CSR and then rekey your GoDaddy certificate to continue the installation process.
The following instructions will guide you through the CSR generation process on Microsoft IIS 7. To learn more about CSRs and the importance of your private key, reference our Overview of Certificate Signing Request article. If you already generated the CSR and received your trusted SSL certificate, reference our SSL Installation Instructions and disregard the steps below.
1. Open Internet Information Services (IIS) Manager
Click Start, Control Panel, Administrative Tools, and then select Internet Information Services (IIS) Manager.
2. Select the server where you want to generate the certificate
In the left Connections menu, select the server name (host) where you want to generate the request.
3. Navigate to Server Certificates
In the center menu, click the Server Certificates icon under the Security section near the bottom.
4. Select Create a New Certificate
In the right Actions menu, click Create Certificate Request.
5. Enter your CSR details
In the Distinguished Name Properties window, enter in the required CSR details and then click Next.

Note: To avoid common mistakes when filling out your CSR details, reference our Overview of Certificate Signing Request article.
6. Select a cryptographic service provider and bit length
In the Cryptographic Service Provider Properties window, select Microsoft RSA SChannel Cryptographic Provider and Bit Length of 2048, then click Next.
Note: Bit Length: 2048 is the current industry standard. You may choose a larger key size, but only if you have a requirement to do so, as longer key lengths increase latency and may reduce compatibility.
7. Save the CSR
Click Browse to specify the location where you want to save the CSR as a “.txt” file and click Finish.
8. Generate the order
Locate and open the newly created CSR from the specified location you choose in a text editor such as Notepad and copy all the text including:
Return to the Generation Form on our website and paste the entire CSR into the blank text box and continue with completing the generation process.
Upon generating your CSR, your order will enter the validation process with the issuing Certificate Authority (CA) and require the certificate requester to complete some form of validation depending on the certificate purchased. For information regarding the different levels of the validation process and how to satisfy the industry requirements, reference our validation articles.
After you complete the validation process and receive the trusted SSL Certificate from the issuing Certificate Authority (CA), proceed with the next step using our SSL Installation Instructions for Microsoft IIS 7.

Sometimes, when an SSL certificate is already installed on a Windows server, you may need to reinstall it on another Windows machine. This may be required when you have a Wildcard or a Multi-domain certificate, and the subdomains or different domains are hosted on different machines.
In this case, the certificate can be moved from one server to another in a PFX file. PFX is a common certificate format for Windows servers. The file in this format contains the certificate associated with its private key and, if applicable, intermediate certificates that sign the domain end-entity certificate. As a rule, it has a *.pfx or *.p12 extension. Basically, creating a PFX file is the only way to export a private key from a Microsoft Windows server on which the CSR code was generated.
Follow these steps to perform the certificate export:
Creating a .pfx file
Creating a .pfx file in MMC
Launch Microsoft Management Console. Press Win+R, type in mmc and press OK.
Click File and select the Add/Remove Snap-in option.
Click on Certificates in the list of Available snap-ins and then, on the Add button.
Select Computer account and click Next.
Choose Local Computer and click on the Finish button.
Click OK to add the certificate snap-in and get back to console.
Expand the Personal store in the left-side menu, and choose Certificates. Right-click on the certificate you want to export >> All Tasks >> Export.
This will run the Certificate Export Wizard.
Select Yes, export the private key.
If the radio button ‘Yes, export the private key’ is grayed out, it means that either the private key was not marked as exportable during the certificate request generation, or that you do not have the corresponding private key on the machine you are using.
Note: if you used IIS Manager certificate request wizard to generate the CSR code, the private key will be marked as exportable by default.
In this case, you will not be able to create a PFX file, only export the certificate without the private key. To have the opportunity to export the certificate to another machine, you will need to create a new CSR code marking the private key as exportable and perform a certificate reissue. Otherwise, you can generate a new CSR code for the same common name on the new machine and import the certificate to it after the reissue is completed.
With a COMODO (now Sectigo) certificate you can perform a reissue an unlimited amount of times for each server.
If you can export the private key, proceed to the next stage. The window Export File Format will have the format Personal Information Exchange – PKCS #12 (.PFX) selected. Please check Include all certificates in the certification path if possible to have the certificate exported with the chain of intermediate CA certificates into a .pfx file. Then click Next.
Note: do not choose ‘Delete the private key if the export is successful’.
Type and confirm password on the next window and click Next. Make sure you remember the password; it will be used later during the import of a .pfx file to a new server.
In the File to Export window select the name and location of the .pfx file to which the certificate and private key will be exported.
Click Finish to complete the export wizard. The certificate has been successfully imported.
Creating a .pfx file via OpenSSL
Iis Generate New Private Key Password
If there’s an OpenSSL client installed on the server, you can create PFX file out of a certificate in PEM format (.pem, .crt, .cer) or PKCS#7/P7B format (.p7b, .p7c) and the private key using the following commands.
PEM (.pem, .crt, .cer) to PFX
*where “more.crt” is the name of the CA Bundle file
PKCS7/P7B (.p7b, .p7c) to PFX
P7B file must be converted to PEM first:
Next, run:
*where “more.crt” is the name of the CA Bundle file
Import a .pfx file to a new machine
The certificate can be imported either using MMC or via Internet Information Services (IIS) Manager.
To perform the import using MMC, add the Certificate snap-in as it was described above, and right-click on Personal >> All Tasks >> Import
It will run the Certificate import wizard:
Select the .pfx file you want to import on your server, click Next.
Specify the certificate password you used when exporting the .pfx file. Optionally, you can check Mark this key as exportable to be able to export it from this server later. Then press the Next button.
On the Certificate store page check Automatically select the certificate store based on the type of certificate. This will place the certificates from the .pfx file into the corresponding folders.
Click Finish. The certificate wizard is completed and the certificate is imported to the new server successfully.
