Complete newbie here.
Somewhere in the process of adding a SSH key, I thought I saw a warning to not use my Public key because of potential security threats. Does that sound right? Still, and on the same page, it says something like the key will ‘typically begin with ssh-ed25519…’ or some such. Well… That appears only in my public key. The private key is, a rather long, random string. What is the purpose of it?
A little digging suggest it is the public key required anyhow.
I would’ve preferred adding a passcode, but nothing seemed to happen when I tried. Something did happen tho, because when I decided to leave it empty next time I get the message that passcodes don’t match. ? This is on Win 10 and using standard Command Prompt.
Command Prompt also generated a “key fingerprint” and an associated “randomart image”. I copied it to a text file, just in case, but, again, have no idea what use it might be.
