The proper one Link to heading
If you don’t have any keys, generate a default one:
ssh-keygen -t ed25519 -a 100 -q -N "" -f ~/.ssh/id_ed25519
And if you want it generated in the current directory do:
ssh-keygen -t ed25519 -a 100 -q -N "" -f "$PWD"/renameme
Change the name by passing the -C argument:
ssh-keygen -t ed25519 -a 100 -q -N "" -f "$PWD"/deploy_key_1 -C deploy_key_1

ssh-keygen -t rsa -b 4096 -q -N "" -f "$PWD"/renameme
