Most of the time once you completed the new SSL installation, you may needed to verify whether the install was success or not even though webserver does not shows any error after the service restart.
I installed many SSL and most of the time clients want to verify the install twice by me or we need to provide some option to verify it by them.
So I decide to include certain command output excerpt on the email which I’m going to reply to the client.
