I have followed the guide Certbot Instructions | Certbot and successfully got a certification at my domain nitrozeus.stream.
i got the following files to my certificate;
privkey.pem : the private key for your certificate.
fullchain.pem : the certificate file used in most server software.
chain.pem : used for OCSP stapling in Nginx >=1.3.7.
cert.pem : will break many server configurations, and should not be used
How do I make them to a PKCS12 / PFX certificate?
My domain is: nitrozeus.stream
I ran this command: Certbot Instructions | Certbot
The operating system my web server runs on is (include version): Windows 10 Pro Virtual Machine
OR, if that fails... openssl pkcs12 -export -in cert.pem -inkey privkey.pem -out YOUR.pfx
But a much simpler, and more automated solution, is to change to a Windows based ACME client - which can create the certs in a PFX format and also install them into the Windows cert store.
where should i write this command? just open up PowerShell and run the command.
do I need to download any software in order to use the openssl command, I've been reading about something that seems like you have to download openssl
The simpler way, how do I set that up? I'm gonna use the .pfx file to my Emby server so if it can be automated easier, then I'm all in
OpenSSL may, or may not, be part of your Windows system.
[if not, you should be able to download it]
[also check "add or remove programs" for it - I know windows now has curl and OpenSSH available]
If the Emby system can use certs directly from the Windows certificate store is the main question now.
