Question, if I can get free valud certs today (there atey sites that give you free ones, I use one for my lemmy site), where's the security?
I mean it's secure against man in the middle, but if my site is hacked, no proof is going to prevent the hackers to distribute whatever they want.
Certificates are to protect against MitM attacks, not prevent your site from getting hacked. You need to secure everything, this is one aspect of it
So why can't I make my own cert? Give the caller my public key and on we go.
You can make your own cert. To make sure your cert belongs to you (your site) it is signed by authority and the client then may verify that authority (which cetificate is preinstalled in their system) in fact had verified ownership of your site and then signed your cert claims with their private key.
