i want to remotely ssh to my home server, and I was wondering if I could just forward port 22 with disabling password login and use pubkey authentication will be safe enough?

Well it‘s true that one can use RSA, which is still save with keys big enough, but if someone wants so save some extra computing power and time ed25519 is the way to go.

    The difference is extremely tiny because asymmetric encryption is only used at the very beginning to securely establish a symmetric key that will be used for everything else afterwards. So you would have to be running this on a smart fridge to notice the speed difference.
