You can generate key by ssh-keygen command. Examples about Ed25519, ECDSA-521, ECDSA-384, ECDSA-256, RSA 4096 bits are show n below.

## Ed25519
$ ssh-keygen -t ed25519

## ECDSA-521
$ ssh-keygen -t ecdsa -b 521

## ECDSA-384
$ ssh-keygen -t ecdsa -b 384

## ECDSA-256
$ ssh-keygen -t ecdsa -b 256

## RSA 4096 bits
$ ssh-keygen -t rsa -b 4096
