How to convert a certificate correctly?

Question

C++ / C#

Hello
I have developed an application in c# and published it with clickonce. I downloaded and tried to install the application, then its launch was blocked by windows smartscreen, which is logical in principle. Having poked around on the Internet, I realized that in order for the application not to block anything, it must be signed with a certificate.
I have a certificate that I bought. It is used for https connections to my site. My certificate has a .crt extension, but I need a different .pfx certificate to sign applications.
What should I do in my case? Is there any way to convert the certificate?
Thank you very much in advance!

Answer 1

Code signing does not use the same certificate that is used for HTTPS on the site.
It needs to be ordered/purchased separately. And its registration by private individuals sometimes causes some difficulties, because it is issued mainly to organizations (even individual entrepreneurs), and not to individuals.
