Without this I cannot configure the sslOptions object for https. Thank you! The answer from Ian Boyd to this question: stackoverflow. Add a comment. Active Oldest Votes. Recovering a certificate where the private key is marked as non-exportable We needed to export the private key of our IIS7 SSL certificate in order to import it in a node. At this point, depending on the root cause of your problem, we suggest starting a command prompt and enter the following command, as it might cure your problem: certutil -repairstore my FBEF3FB8C5CBCE03CDA3C2A3 If the problem is not cured and the private key remains non-exportable, continue Once you import the new certificate you can delete the old.

I had the same issue. Ran the command using CMD certutil —repairstore my serialnumber You can find the serialnumber from the certificate details tab. Possible reasons are: If your CA isn't a Microsoft one or even if it is, but you created the certificate on another box , you exported the certificate only, without exporting the private key.

For example, if a certificate will be used on a web server to encrypt communication for all clients, placing a certificate in a store in the computer context would be ideal. This allows for certificates in a computer certificate store to be used by all users, depending on the permissions configured for the private key.

For more information on private keys, be sure to check out the article X. Below you can see a breakdown of where each type of store is located in the registry and file system. Throughout the rest of this article, you will find multiple examples showing interactions with Windows certificate stores.

To replicate these examples, be sure you meet the following prerequisites:. Since certificates can be managed a few different ways in Windows, which one do you choose?

First, consider the lifecycle of a certificate. If you only intend to install or remove a single certificate once, consider using the MMC. This initial view will provide an overview of all the logical stores displayed in the left window.

You can see in the screenshot below the Trusted Root Certification Authorities logical store is selected. By default, the Windows certificate manager will not show the actual physical stores. To show the stores, click on View and then on Options. You will then see options to choose to show physical certificate stores.

Enabling this option makes identifying the specific paths within Windows easier. You can now see additional containers are shown under the example Trusted Root Certification Authorities logical store shown previously. There are many attributes of a certificate you can see when viewing them with the MMC. For example, you will likely want to select specific certificates. If the certificate was signed by a certificate authority CA , it will have a serial number when issued.

The Thumbprint is calculated every time the certificate is viewed. You can see some of the attributes for a certificate by opening it up in the MMC as you can see below. One important feature to point out is embedded private keys. Certificates in Windows can also have a corresponding private key.

These private keys are stored in corresponding physical stores as encrypted files. To quickly distinguish a certificate with and without a corresponding private key, look at the certificate icon.

In the Windows certificate manager, if the icon simply looks like a piece of paper with a ribbon, there is no corresponding private key. If a certificate does have a private key, you will see a key in the MMC icon, and you will see a key at the bottom of the General tab when you open the certificate.

You can see an example output of this below. Another common store is, the Personal store. Your certificates for this store are located on the file system rather than the Registry.

In the following commands we will show these different physical paths and their purposes. Each file in the directory, returned by the command below, corresponds to a certificate installed in the Personal current user store. Each file returned in the below command is a reference to the object for a private key created by the Key Storage Provider KSP.

The file name corresponds to the Subject Key Identifier of the certificate. Each private key you install will have a corresponding file added. Each file in the directory returned by the below command is the unique container for the encrypted private key created by the KSP. There is no direct relationship between the file name and the certificate, but the file is the target of the pointer in the earlier command. Since working with certificates in their physical paths is uncommon, you will be working with the logical stores for the rest of the examples.

When you are working with certificates you will need a way to filter and select certificates to perform specific operations against. Most of the time you will filter and select certificates based on the value of a specific extension. For the following examples you need to start by listing all installed certificates in the root CA store.

Common extensions are already available as properties of the certificate objects. In the below example you are using Get-Member to list all the properties of the returned objects. As you can see in Figure 9, some of these extensions, like Issuer, are helpful for finding the certificate you are looking for. Extensions supply information about the certificate, such as who it is issued to, what it can be used for, and any restrictions on it.

In more complex use cases you will want to find certificates by other extensions, like the certificate template used. The difficulty is the values for these extensions return as an array of integers. These integers correspond to ASN. The existing ScriptProperties available on the object show examples for interfacing with these.

Select the PKCS 12 option. Check the box for "Include all certificates in the certification if possible". If you will no longer need the certificate and private key on this system check "Delete the private key if the export is successful". Do not select this option if you still need to use this certificate on this system. Check the box to "Export all extended properties".

Click "Next". Provide a password for the private key if you are prompted. Save the file somewhere safe as something like certname. Extracting the Certificate and Private Key A. Have a question? Contact us at iam-support uw.
