[SOLVED] Can I host my own Lemmy instance on localhost?

Octopus@thelemmy.club to Selfhosted@lemmy.world – 30 points –

Would it be possible for me to make comments to other instances etc?

Solved: I can't, it would only work with a public domain.

Data send via HTTP is not encrypted. That's bad.

I want it encrypted but I don't want to ask a 3rd party to get a certificate.

Letsencrypt provides free certificates. It's very easy to get one from them.

If they're easy to get, why have them 😑

I'm not sure I understand the question. They are used to encrypt traffic and prove that the entity hosting the site hasn't changed by using a digital signature. These two together make it so third parties can't read the traffic coming through. This is a requirement for modern internet. Otherwise your passwords wouldn't be a secret because literally anyone would see them.
