Generate your SSH key

In a Terminal on your computer, run:

ssh-keygen -t ed25519

This command will generate the following output:

Generating public/private ed25519 key pair.
Enter file in which to save the key (/Users/***/.ssh/id_ed25519): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /Users/***/.ssh/id_ed25519.
Your public key has been saved in /Users/***/.ssh/
  • Press Enter to confirm the default name of the file containing the key
  • Don’t enter any passphrase: press Enter twice

Finally the key is generated and a randomart image is displayed.

The key fingerprint is:

The key's randomart image is:
+--[ED25519 256]--+
|  ..++.o         |
| .   .-          |
|.  . .           |
| .=  ..          |

| .. o+.oo        |
|.. . *=..+ ..    |
|..E+. +=B =o..   |
|o.o o+==oB=+o.   |

Display your public key with:

cat ~/.ssh/

This command will generate the following output (with your own key):
