Slightly OT: Windows Code Signing

Thank you Matthias,

I did notice the unexpectedly large price on Sectigo direct and purchase 
a 3 year through for about $212.50 USD, so at an okay 
price for me. Mine is just a plain signing cert, not the EV.

What I ran into that was very frustrating was the browser requirements. 
You would think - especially with the vagueness of browsers supporting 
certain features - that they would make an app to do their own CSR 
generation at the start of the process and the same app can do the 
download at the end

I do not have any older version of IE (on VMs or otherwise). I did 
download Firefox 68 (current release is 82!, but 68 is only from early 
2019) but could not get it to work. Finally I was able to download my 
cert via Safari under Mojave and move it to my Windows 10 via Dropbox 
and under Windows 10 use the MMC (Microsoft Management Console) to 
import it and export it in p12 (.pfk) format for use in signing 
Standalones. Success, but what a pain to go through.

If anyone has found a Issuer that will just let you download the code 
signing cert as a .p12 pr .pfk file, I'd like to know.

And i was able to download the certificate on my Windows 10 VM with Internet Explorer, if i remember right. I even cannot remember that a special version of Mozilla was required.
