Steps to generate and to validate a certificate

Prerequisite: you must have a website accessible from your domain name (in http). Indeed, the validation of LetsEncrypt tries to check the presence of a file available in your website.

1. Go to Azure portal, navigate to your Advanced Tools (Kudu environment). And select Debug console / CMD.

2. Install this tool, using this command:

    dotnet tool install dvoituron.tools.azureletsencrypt --tool-path tools
   

3. Run this command, using your domains and password.

    .\tools\AzureLetsEncrypt --domains=mydomain.com,www.mydomain.com --password=MyPassword
   

4. You can download your validated Pfx certificate from the subfolder ./store of your website.

5. In the Azure portal, go to SSL settings panel, to upload your Pfx.

   • Private certificate: upload your Pfx file (using your password)
   • Bindings: Add a SSL Binding using a SNI based

When to renew the certificate?

LetsEncrypt's certificates expire after 90 days. This is an obligation imposed by LetsEncrypt. So, you need to reproduce these steps, each 3 months.
