Before you can order an SSL certificate, it is recommended that you generate a Certificate Signing Request (CSR) from your server or device. Learn more about SSL certificates » A CSR is an encoded file that provides you with a standardized way to send DigiCert your public key as well as some. Diary apps for mac and iphone. Jan 30, 2017 When renewing a certificate it is not necessary to generate a new csr. This is possible by maintaining the same private key. When received the renewed certificate from the 3rd party certification authority, we can try to import it and assign the private key from the management console (mmc - certificates).
General CSR Creation Guidelines
During SSL setup, if you’re on a Windows-based system, there may be times when you need to generate your Certificate Signing Request (CSR) and Private key outside the Windows keystore. This may be useful, for example, if you want to backup your SSL Certificate or import it to multiple servers. In order to create a CSR, users need two types of keys known as private and public keys. Next, in order for the CSR to be generated by all keys, the password and certificate must contain the same.

A CSR is an encoded file that provides you with a standardized way to send DigiCert your public key as well as some information that identifies your company and domain name. When you generate a CSR, most server software asks for the following information: common name (e.g., www.example.com), organization name and location (country, state/province, city/town), key type (typically RSA), and key size (2048-bit minimum).
If you aren't sure of the exact company name or location when you generate the CSR, don't worry; we can change and finalize that information during our review process before we issue the certificate.
Once your CSR is created, you'll need to copy and paste it into the online order form when you go to purchase your SSL certificate. Online Certificate Order Form »

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. Download mac snow leopard online. 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:
Prerequisites
Create a root CA certificate
Create your root CA certificate using OpenSSL.
Create the root key
Create a Root Certificate and self-sign it
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 .
Generate the certificate with the CSR and the key and sign it with the CA's root key
Verify the newly created certificate
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.
ApacheWindows Generate Csr From Existing Key And Cert Key
The following configuration is an example virtual host configured for SSL in Apache: Reimage license key windows 10.
NGINX
The following configuration is an example NGINX server block with TLS configuration:
Access the server to verify the configuration
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.
Azure portal
To upload the trusted root certificate from the portal, select the HTTP Settings and choose the HTTPS protocol.
Azure PowerShell
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
