No files with prefix com.apple.security in Library?

I have been having issues with Safari not showing https sites. The best solution I have found googling around seems to be to delete either "com.apple.security.plist" or "com.apple.security.revocation.plist", but in Library/Preferences I have no mention of any com.apple.security file.

I have not found anything that seems applicable to this exact problem. Could anyone shed light on why this file might be missing, and/or how to restore it?

I have tried:

resetting Safari

rebooting

Keychain first aid, no errors

opening Terminal and executing "ls -l ~/Library/Preferences/com.apple.*.plist", no file in results.

Thanks much
