What is auto-generating self-signed certificates on MacOS (Ventura)
I had created a self-signed certificate prior to the release of OS Ventura to allow email verification and signing (I'm not really interested in encryption), however I found that in the Apple email client, after updating to Ventura, this causes an error dialog to popup when sending email. The dialog states that because the public keys for the addressee are not available the message can't be encrypted. It does allow an override to send the email without encryption, but this has to be done for each email sent.
By deleting all my self-signed certificates I'm able to get the email client to send without the popup for a period of time, however something causes a self-signed certificate to be regenerated in the login keychain under "My Certificates" and the problem repeats.
I don't know what causes this certificate to be generated.I wouldn't have expected the certificate to auto-generate. It doesn't happen with each login, and also not after every system restart. This doesn't seem like correct behavior.
