MacOS 10.13 and cerbot installation errors using HomeBrew

I realize MacOS 10.13 is not supported, but... pretty please.

Can someone help me understands these cerbot install errors when using homebrew:

Upon entering the command "brew install certbot", i get this response -

==> Searching for similarly named formulae...
Error: No similarly named formulae found.
Error: No available formula or cask with the name "certbot".

==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.

==> Searching taps on GitHub...
Error: No formulae found in taps.

IF (it is simply not posible to install certbot on MacOS 10.13.6) THEN perhaps some loving soul could inform me so I dont waste time.

ALSO, perhaps there is a manual way to install Lets Encrypt - please let me know.

IF ALL ELSE FAILS, can I simply set up a new maching to generate the Lets Encrypt Certificate and then simply transfer them to my Web Server/Key Chain?

Thank you for any of your thoughts,

Yes. But keep in mind that the lifetime of a certificate is only 90 days, so you need some method of automation on your workflow.

For the macOS stuff - I don't know.

Thank you Nummer378 for your kind reply, I was unaware of the 90 day lifetime. I will use script to automate the renewal process.

IF (any member has written such a script) perhaps you could share your algorithm or code with me to run on MacOS. otherwise, I will post my MacOS 13.0 solution for this community.

Peace & Harmony To All
