Creating SSH keys

Generate a new key

If you don’t have an existing SSH key that you wish to use, generate one as follows:

1. Open a terminal on your local computer and enter the following:

   ssh-keygen -t ed25519 -C "your_email@example.com"

   Associating the key with your email address helps you to identify the key later on.

   You’ll see a response similar to this:

   chaiss@C02FP1JWMD6V ~ % ssh-keygen -t ed25519 -C chaiss@email.com
   Generating public/private ed25519 key pair.
   Enter file in which to save the key (/Users/chaiss/.ssh/id_ed25519): 

2. Just press <Enter> to accept the default location and file name. If the .ssh directory doesn’t exist, the system creates one for you.

3. Enter, and re-enter, a passphrase when prompted.
   The whole interaction will look similar to this:

   chaiss@C02FP1JWMD6V ~ % ssh-keygen -t ed25519 -C chaiss@email.com
   Enter file in which to save the key (/Users/chaiss/.ssh/id_ed25519): 
   Enter passphrase (empty for no passphrase): 
   Enter same passphrase again:
