New Certificate with longer validity

I read the following gemlog post:

RE ew0k: Your Gemini Browser and Server are Probably Doing Certificates Wrong

Which to took me to this post:

Your Gemini Browser and Server are Probably Doing Certificates Wrong

And I read this advice:

> And server admins: please, please, please stop using Certificate Authority certificates until this situation is sorted out. And set not-valid-after dates to at least some time in the next century. If TOFU is decided as the predominant validation scheme I suggest you never return to using Certificate Authority certificates. They just can't be guaranteed to play well with TOFU.

So I decided to check the validity of my own certificate which is self-signed...

Dec 21 18:07:47 2021 GMT

Okay, that's not a very long period of time. :-) I replaced my certificate with a new one. This new certificate will be valid until:

Jun 8 23:02:45 3020 GMT

That's better.

This replacement shouldn't cause any problems because my server is still unknown. (I submitted a crawl request to GUS but the search index hasn't been updated since 2020-12-06.)

By the way, to check the expiration date I used the following openssl command which I found here:
