Enter a file inwhich to save the key (/Users/you/.ssh/id_rsa): [Press enter]
At the prompt, type a secure passphrase. For more information, see “Working with SSH key passphrases”.

将 SSH Key 添加到 ssh-agent
Start the ssh-agent in the background.
1 2
eval"$(ssh-agent -s)" Agent pid 59566
If you’re using macOS Sierra 10.12.2 or later, you will need to modify your ~/.ssh/config file to automatically load keys into the ssh-agent and store passphrases in your keychain.
Add your SSH private key to the ssh-agent and store your passphrase in the keychain. 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.
