A Key Vault (KV) certificate can be either created or imported into a key vault. When a KV certificate is created the private key is created inside the key vault and never exposed to certificate owner. The following are ways to create a certificate in Key Vault: Create a self-signed certificate: This will create. Nov 29, 2017 If you try to export a certificate from the Issued folder on the CA, you can only export (Copy To File) as a.cer file, which won’t include the private key. If you follow the steps above to export the certificate, you can still import the certificate onto the server, but in the Certificate Manager MMC, you won’t see the key icon showing that it has a private key.

Objective

Citrix Secure Web Gateway, formerly NetScaler Secure Web Gateway

This article provides steps to export a root CA certificate with private key from a Microsoft Authority Server. This root CA certificate can be used on your NetScaler Secure Web Gateway server.

Instructions

1.Log on to the Domain Controller that has the target Certificate Authority installed.

2. Open the Certificate Authority MMC (run certsrv.msc).

3. Right-click the CA name in the tree ('npgftl-FTLRNPGDC1-CA' in the example), and select All Tasks > Back up CA.

The Certification Authority Backup Wizard starts.

4. On the Certification Authority Backup Wizard screen click Next

5. On the Items to Back Up page, select Private key and CA certificate, enter a location in which to save the file, and click Next.

6. On the Select a Password page, enter a password and confirm it. This password will be required when processing and importing the key into NetScaler Secure Web Gateway server.

7. Click Next and then Finish. When the process is complete, you will have a .p12 file (example CA_name.p12) file in the folder you specified. This file contains both the public key and private key for the certificate.

8. Next, using OpenSSL or the NetScaler GUI export the private key and certificate from the .p12 file format.

Login to NetScaler GUI console
9.Click Configuration-->Traffic Management-->SSL.

10.From the Tools node, Click Import PKCS#12

The Application Gateway v2 SKU introduces the use of Trusted Root Certificates to allow backend servers. This removes authentication certificates that were required in the v1 SKU. The root certificate is a Base-64 encoded X.509(.CER) format root certificate from the backend certificate server. It identifies the root certificate authority (CA) that issued the server certificate and the server certificate is then used for the TLS/SSL communication.

Application Gateway trusts your website's certificate by default if it's signed by a well-known CA (for example, GoDaddy or DigiCert). You don't need to explicitly upload the root certificate in that case. For more information, see Overview of TLS termination and end to end TLS with Application Gateway. However, if you have a dev/test environment and don't want to purchase a verified CA signed certificate, you can create your own custom CA and create a self-signed certificate with it.

Note

Self-signed certificates are not trusted by default and they can be difficult to maintain. Also, they may use outdated hash and cipher suites that may not be strong. For better security, purchase a certificate signed by a well-known certificate authority.

In this article, you will learn how to:

• Create your own custom Certificate Authority
• Create a self-signed certificate signed by your custom CA
• Upload a self-signed root certificate to an Application Gateway to authenticate the backend server

Prerequisites

• OpenSSL on a computer running Windows or Linux

  While there could be other tools available for certificate management, this tutorial uses OpenSSL. You can find OpenSSL bundled with many Linux distributions, such as Ubuntu.

• A web server

  For example, Apache, IIS, or NGINX to test the certificates.

• An Application Gateway v2 SKU

  If you don't have an existing application gateway, see Quickstart: Direct web traffic with Azure Application Gateway - Azure portal.

Create a root CA certificate

Create your root CA certificate using OpenSSL.

Create the root key

1. Sign in to your computer where OpenSSL is installed and run the following command. This creates a password protected key.

2. At the prompt, type a strong password. For example, at least nine characters, using upper case, lower case, numbers, and symbols.

Create a Root Certificate and self-sign it

1. Use the following commands to generate the csr and the certificate.

   The previous commands create the root certificate. You'll use this to sign your server certificate.

2. When prompted, type the password for the root key, and the organizational information for the custom CA such as Country, State, Org, OU, and the fully qualified domain name (this is the domain of the issuer).

Create a server certificate

Next, you'll create a server certificate using OpenSSL.

Create the certificate's key

Use the following command to generate the key for the server certificate.

Create the CSR (Certificate Signing Request)

The CSR is a public key that is given to a CA when requesting a certificate. The CA issues the certificate for this specific request.

Note

The CN (Common Name) for the server certificate must be different from the issuer's domain. For example, in this case, the CN for the issuer is www.contoso.com and the server certificate's CN is www.fabrikam.com.

1. Use the following command to generate the CSR:

2. When prompted, type the password for the root key, and the organizational information for the custom CA: Country, State, Org, OU, and the fully qualified domain name. This is the domain of the website and it should be different from the issuer.

Generate the certificate with the CSR and the key and sign it with the CA's root key

Key Microsoft Office 2010

1. Use the following command to create the certificate:

Verify the newly created certificate

1. Use the following command to print the output of the CRT file and verify its content:

2. Verify the files in your directory, and ensure you have the following files:

   • contoso.crt
   • contoso.key
   • fabrikam.crt
   • fabrikam.key

Configure the certificate in your web server's TLS settings

In your web server, configure TLS using the fabrikam.crt and fabrikam.key files. If your web server can't take two files, you can combine them to a single .pem or .pfx file using OpenSSL commands.

IIS

For instructions on how to import certificate and upload them as server certificate on IIS, see HOW TO: Install Imported Certificates on a Web Server in Windows Server 2003.

For TLS binding instructions, see How to Set Up SSL on IIS 7.

Apache

The following configuration is an example virtual host configured for SSL in Apache:

NGINX

The following configuration is an example NGINX server block with TLS configuration:

Access the server to verify the configuration

1. Add the root certificate to your machine's trusted root store. When you access the website, ensure the entire certificate chain is seen in the browser.

   Note

   It's assumed that DNS has been configured to point the web server name (in this example, www.fabrikam.com) to your web server's IP address. If not, you can edit the hosts file to resolve the name.

2. Browse to your website, and click the lock icon on your browser's address box to verify the site and certificate information.

Verify the configuration with OpenSSL

Or, you can use OpenSSL to verify the certificate.

Upload the root certificate to Application Gateway's HTTP Settings

To upload the certificate in Application Gateway, you must export the .crt certificate into a .cer format Base-64 encoded. Since .crt already contains the public key in the base-64 encoded format, just rename the file extension from .crt to .cer.

Key Microsoft 2016

Azure portal

To upload the trusted root certificate from the portal, select the HTTP Settings and choose the HTTPS protocol.

Azure PowerShell

Generate Cert And Key Microsoft Ca Server

Or, you can use Azure CLI or Azure PowerShell to upload the root certificate. The following code is an Azure PowerShell sample.

Note

The following sample adds a trusted root certificate to the application gateway, creates a new HTTP setting and adds a new rule, assuming the backend pool and the listener exist already.

Verify the application gateway backend health

1. Click the Backend Health view of your application gateway to check if the probe is healthy.
2. You should see that the Status is Healthy for the HTTPS probe.
