In the development environment we can use a self-signed certificate, but for production environment we will need a commercial certificate to publish Apps to store. So we will follow below steps to create a self signed certificate.

1. Open IIS Manager, and click on Server Certificates. (start > Run > inetmgr)

2. Double click on Server Certificates. It will open Server Certificates window, Click on Create Self Signed Certificate from Right most Action window.

3. Enter some meaningful name like "SharePointOnlieTest" and Click on Ok.

4. Certificate is created and will be displayed in Server Certificates window.

5. Now we need to export the personal exchange format (.pfx) file. Right Click on the "SharePointOnlieTest" Certificate in IIS click on Export and provide an accessible location. Also enter the password that you want to use and Click on Ok.

6. Now double click on the "SharePointOnlieTest" Certificate in IIS. Click on Details tab and click on Copy to File.
