Where can I get an S/MIME email certificate and import it into the keychain?
My S/MIME email certificate just expired, and I'd like to get another one. I got this expired certificate from Sectigo and it was a nightmare to get it into the keychain. I had to download some files from Sectigo then use openssl to massage the files into something that Monterey could understand.
Is there an easier way to do this? Where can I get an S/MIME certificate that is easier to install?
