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. 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.
At the prompt, change the Common Name to your client's domain name using the format client2.example.com. Leave all of the remaining fields as the default values.
Mar 29, 2018 Private Key – Again, this is my first CA so I’m going to generate a new private key. If we had already generated a private key and didn’t wish to disturb the operation of existing certificates we could chose to Use an existing key. Cryptography – Go ahead and leave the defaults here – ensuring we have the Microsoft Key Storage Provider (RSA) selected, along with a key length of 2048. CA Name – give your CA a common name. For example, I used mwpreston-CA for mine. Jul 09, 2019 The Private Key is generated with your Certificate Signing Request (CSR). The CSR is submitted to the Certificate Authority right after you activate your Certificate. The Private Key must be kept safe and secret on your server or device, because later you’ll need it for Certificate installation. Jul 25, 2017 To request a certificate from a CA like Verisign, you send them a Certificate Signing Request (CSR), and they give you a certificate in return that they signed using their root certificate and private key.
Important: If you don't follow the format specified above for setting common names, the domain names aren't available when you import the certificate into ACM. As a result, the certificate isn't an available option for specifying the server certificate or client certificate when you create the AWS Client VPN endpoint.
Import the server and client certificates and keys into ACM
Note: The server and client certificates, and their respective keys, are available in C:Program FilesOpenVPNeasy-rsakeys.
1. Open the following files: server.crt, server.key, client1.crt, client1.key, and ca.crt.
2. Open the ACM console, and then choose Import a certificate.
3. On the Import a certificate page, copy/paste the content:
From the server.crt file to Certificate body.
From the server.key file to Certificate private key.
From the ca.crt file to Certificate chain.
4. Choose Import to import the server certificate.
5. Choose Import a certificate again and copy/paste the content:
From the client1.crt file to Certificate body.
From the client1.key file to Certificate private key.
From the ca.crt fileto Certificate chain.
6. Choose Import to import the client certificate.
Or, you can use the AWS Command Line Interface (AWS CLI) to import the server and client certificates and their keys into ACM:
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:
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 your root CA certificate using OpenSSL.
Sign in to your computer where OpenSSL is installed and run the following command. This creates a password protected key.
At the prompt, type a strong password. For example, at least nine characters, using upper case, lower case, numbers, and symbols.
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.
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).
Next, you'll create a server certificate using OpenSSL.
Use the following command to generate the key for the server certificate.
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
.
Use the following command to generate the CSR:
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.
Use the following command to create the certificate:
Use the following command to print the output of the CRT file and verify its content:
Verify the files in your directory, and ensure you have the following files:
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.
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.
The following configuration is an example virtual host configured for SSL in Apache:
The following configuration is an example NGINX server block with TLS configuration:
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.
Browse to your website, and click the lock icon on your browser's address box to verify the site and certificate information.
Or, you can use OpenSSL to verify the certificate.
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.
To upload the trusted root certificate from the portal, select the HTTP Settings and choose the HTTPS protocol.
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.
