I tried to create a certificate by this way.

  1. Install  "fiddlercertmaker.exe" (get it from http://fiddler2.com/r/?fiddlercertmaker/.)
  2. ”prefs set fiddler.certmaker.bc.ee.yearsvalid 1”
  3. Options -> HTTPS tab -> "Actions" -> ”Reset All Certificates”
  4. Options -> HTTPS tab -> "Actions" -> ”Trust Root Certificates" 

see config.jpg and Option.jpg

However, the term of the certificate is 10 years.”Certificates.jpg”

If my understanding is mistaken, please tell me.

Thank you for your advice.
I had a mistake. I thought the duration of the root certificate needed to be one-year.

As you pointed out, for the browser certificate, it showed up as 1 year.
The certificate error on MacOS11 has been resolved.

Fiddler uses two types of certificates - a root certificate and a domain specific certificate for each web site. The root certificate is not used directly on web sites - it is generated once per machine and has a long validity period. The other certificate is the one you see in the browser when you go to a web site and it is the one that you have to set to be valid for one year. If you are using the cert maker generator, the web site certificate is not added to the user's certificate store (the one you show in the "Certificates.jpg" screenshot). Only the root certificate is added there.

If you want to see the web site certificate, you have to do it from the browser. Click the lock icon and then certificate to see it.
