generating a new ssh key for github code example
Example 1: create ssh key mac github
$ ssh-keygen -t ed25519 -C "[email protected]"
Example 2: Add your SSH private key to the ssh-agent. If you created your key with a different name, or if you are adding an existing key that has a different name, replace id_rsa in the command with the name of your private key file.
$ cat ~/.ssh/id_rsa.pub
