ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/YOUR_USER/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/YOUR_USER/.ssh/id_rsa
Your public key has been saved in /Users/YOUR_USER/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:ViVROMPZl6BiB6B15FlPjk6TUx8Nxxxxxxx YOUR_USER@YOUR_hostname
The key's randomart image is:
