SSH keys are a way to identify trusted computers， without involving passwords。 The steps below will walk you through generating an SSH key and then adding the public key to your GitHub account。

Tip： We recommend that you regularly review your SSH keys list and revoke any that haven‘t been used in a while。

Step 1： Check for SSH keys

First， we need to check for existing SSH keys on your computer。 Open up your Terminal and type：

［plain］ view plaincopyls -al ~/。ssh # Lists the files in your 。ssh directory， if they exist

Check the directory listing to see if you already have a public SSH key。 The default public key file names are：

id_dsa。pub

id_ecdsa。pub

id_ed25519。pub

id_rsa。pub

Tip： If you have a new installation of Mac OSX， you will not have a~/。ssh directory。 It will be created when you run the ssh-keygen command instep 2below。

Step 2： Generate a new SSH key

To generate a new SSH key， copy and paste the text below， making sure to substitute in your email address。 The default settings are preferred， so when you’re prompted to “Enter a file in which to save the key”， just pressEnter to continue。
