I am back with another published article.

Please be kind! I am a self-taught Linux user and by no means an expert. My goal with this guide is to help newcomers to Linux have an easier and more secure start.

To all the experts out there, please be kind and do share your tips and observations. I am happy to keep updating the article to make the self-hosting world more secure.

Mozilla has some guidelines for SSH which I use: https://infosec.mozilla.org/guidelines/openssh

Only thing I do differently is I use ed25519 instead of RSA.

ssh-keygen -t ed25519 -a 100

Thanks!

I saw the ed25519 keys sometime ago, but haven’t had time to understand it.

Will look into it and the link!

Same protections as RSA but more efficient cause same strength of security but with shorter length making it fast.

There is Edsa too but since it was developed by NSA, people are skeptic it may have a back door…
