In order to develop a web application that requires secure base URL for users on HTTPS such as Facebook application, testing cookies across HTTP and HTTPS, etc; we will need to install a Free SSL Certificate just for testing on development environment.
On Windows Server 2008, IIS 7, we can easily create a Self-Signed Certificate SSL Certificate then bind your website to that SSL Certificate. Meaning we have free SSL Certificates; no cost, no sign up, no commitment.
However, please keep in mind that a Self-Signed Certificate is a certificate that is signed by itself instead a trusted third party. Because of this, Self-Signed Certificate can be used ONLY for testing purpose or just on development server.
This tutorial describes steps to create a Self-Signed Certificate and bind the Self-Signed Certificate to your website.
1. Creating Self-Signed Certificate in Windows IIS 7
1. Open Internet Information Services (IIS) Manager (Start => Control Panel => Administrator Tools => Internet Information Services (IIS) Manager).
2. Click on Server Name on the left then double click on Server Certificates icon.

Open a browser and try with the HTTPS url such as: https://ssl.4rapiddev.com:8443/. You will receive an un trsuted error message like these: “There is a problem with this website’s security certificate.” – Internet Explorer, “This Connection is Untrusted” – Firefox or “The site’s security certificate is not trusted!” – Google Chrome.
Testing Self-Signed Certificate SSL Certificate
Simply confirm the risk and you’ve done. Now you can develop your web application with SSL Certificate and run it on HTTPS without pay
