+# Configuring Configuring SSL certificate(HTTPS)
+
+A website needs an SSL certificate in order to keep user data secure, verify ownership of the website, prevent attackers from creating a fake version of the site, and gain user trust.
+
+This document introduces how to get and use SSL certificate(HTTPS) for your application.
+
+## Get a SSL Certificate from a Certificate Authority
+
+You can get a SSL certificate from a certificate authority (CA) such as [Let's Encrypt](https://letsencrypt.org/) or [Cloudflare](https://www.cloudflare.com/learning/ssl/what-is-an-ssl-certificate/) and so on.
+
+Once you have a certificate, you need to configure your web server to use it. The following references show how to configure your web server to use a certificate.

+* [Host ASP.NET Core on Linux with Nginx: HTTPS configuration](https://learn.microsoft.com/en-us/aspnet/core/host-and-deploy/linux-nginx)
+* [How to Set Up SSL on IIS 7 or later](https://learn.microsoft.com/en-us/iis/manage/configuring-security/how-to-set-up-ssl-on-iis)
+
+## Create a Self-Signed Certificate
+
+You can create a self-signed certificate for testing purposes or internal use.
+
+There is an article about [how to create a self-signed certificate](https://learn.microsoft.com/en-us/dotnet/core/additional-tools/self-signed-certificates-guide), If you are using IIS, you can use the following this document to [obtain a Certificate](https://learn.microsoft.com/en-us/iis/manage/configuring-security/how-to-set-up-ssl-on-iis#obtain-a-certificate)
+
+## Common Problems
+
+### The remote certificate is invalid because of errors in the certificate chain: UntrustedRoot
+
+This error may occur when using IIS. You need to trust your certificate by `Manage computer certificates`.
