How to create .pfx file

In order to use in IIS (version 8 ) https we need to import a certificate which has to be associated to https binding .

If you buy or get a free ssl certificate you can convert it to a pfx file like this :

openssl pkcs12 -export -out domain.name.pfx -inkey domain.name.key -in domain.name.crt

Openssl can be downloaded from here.

If you have a root CA or intermediate certificate you can append it by supplying multiple -in parameter:

openssl pkcs12 -export -out domain.name.pfx -inkey domain.name.key -in domain.name.crt -in intermediate.crt -in rootca.crt

Now that you have the pfx you can just import it in IIS 8 and use it .
