Generate Private Key From Iis

 admin

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. Generate Private Key From A Public Key
  2. Generate Private Key From Iis To Another
  3. Import Private Key Iis

Export private key and certificate from IIS.pfx file If you need to move or copy a certificate from Windows IIS6 to Linux Apache server (or other device requiring.key and.crt formats) perform following steps.

1. Open Internet Information Services (IIS) Manager

  • Back Up Private Key. To backup a private key on Microsoft IIS 6.0 follow these instructions: 1. From your server, go to Start Run and enter mmc in the text box. Click on the OK button. From the Microsoft Management Console (MMC) menu bar, select Console Add/Remove Snap.
  • Export Certificate and Private Key from a Microsoft IIS 6.0 server. Part 1: Create an MMC Snap-in for Managing Certificates. From the Web server, click Start Run. In the text box, type mmc. From the Microsoft Management Console (MMC) menu bar, select File Add/Remove Snap-in.
  • Export Certificate and Private Key from a Microsoft IIS 6.0 server. Part 1: Create an MMC Snap-in for Managing Certificates. From the Web server, click Start Run. In the text box, type mmc. From the Microsoft Management Console (MMC) menu bar, select File Add/Remove Snap-in.
  • Jul 09, 2019 When you import your Certificate via MMC or IIS, the Private Key is bound to it automatically if the CSR/Key pair has been generated on the same server. If you need to obtain the Private Key to install your Certificate on a different server, you can export the key in a password protected PFX (PKCS#12) file.
  • Sep 11, 2018  The private key must correspond to the CSR it was generated with and, ultimately, it needs to match the certificate created from the CSR. If the private key is missing, it could mean that the SSL certificate is not installed on the same server which generated the Certificate Signing Request. A CSR usually contains the following information.

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

Generate Private Key From A Public Key

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:

Generate Private Key From Iis To Another

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.

The machineKey element of the ASP.NET web.config specifies the algorithm and keys that ASP.NET will use for encryption. By default the validationKey and the decryptionKey keys are set to AutoGenerate which means the runtime will generate a random key for use. This works fine for applications that are deployed on a single server. When you use webfarms a client request can land on any one of the servers in the webfarm. Hence you will have to hardcode the validationKey and the decryptionKey on all your servers in the farm with a manually generated key.

There are a lot of articles that describe how to use RNGCryptoServiceProvider to generate a random key. There are also a lot of online tools that generate random keys for you. But I would suggest writing your own script because any one who has access to these keys can do evil things like tamper your forms authentication cookie or viewstate.

With IIS 7 you no longer have to do this manually. The IIS 7.0 manager has a built in feature that you can use to generate these keys.

It uses RNGCryptoServiceProvider internally to create a random key. The value is stored locally in the web.config of that application something like

<?xml version='1.0' encoding='UTF-8'?>
<configuration>
<system.web>
<machineKey decryptionKey='F6722806843145965513817CEBDECBB1F94808E4A6C0B2F2,IsolateApps' validationKey='C551753B0325187D1759B4FB055B44F7C5077B016C02AF674E8DE69351B69FEFD045A267308AA2DAB81B69919402D7886A6E986473EEEC9556A9003357F5ED45,IsolateApps' />
</system.web>
</configuration>

You can copy it and paste it in the web.config file of all the servers in the webfarm. Generate ssh key without prompt.
