You generate an SSH key through macOS by using the Terminal application. Once you upload a valid public SSH key, the Triton Compute Service uses SmartLogin to copy the public key to any new SmartMachine you provision.

Joyent recommends RSA keys because the node-manta CLI programs work with RSA keys both locally and with the ssh agent. DSA keys will work only if the private key is on the same system as the CLI, and not password-protected.

About Terminal

Sep 26, 2019 You generate an SSH key through macOS by using the Terminal application.

Jun 26, 2019 Create a label for your key, then paste in the contents of your public SSH key (idrsa.pub): Click Add Key. When you next create a Linode you’ll be given the opportunity to include your SSH key in the Linode’s creation.
Before adding a new SSH key to the ssh-agent to manage your keys, you should have checked for existing SSH keys and generated a new SSH key. When adding your SSH key to the agent, use the default macOS ssh-add command, and not an application installed by macports, homebrew, or some other external source.

Terminal is the terminal emulator which provides a text-based command line interface to the Unix shell of macOS.

To open the macOS Terminal, follow these steps:

Run it on your local computer to generate a 2048-bit RSA key pair, which is fine for most uses. Ssh-keygen The utility prompts you to select a location for the keys. By default, the keys are stored in the /.ssh directory with the filenames idrsa for the private key and idrsa.pub for the public key.

In Finder, choose Utilities from the Applications folder.
Find Terminal in the Utilities listw.
Open Terminal.

The Terminal window opens with the commandline prompt displaying the name of your machine and your username.

Generating an SSH key

An SSH key consists of a pair of files. One is the private key, which should never be shared with anyone. The other is the public key. The other file is a public key which allows you to log into the containers and VMs you provision. When you generate the keys, you will use ssh-keygen to store the keys in a safe location so you can bypass the login prompt when connecting to your instances.

To generate SSH keys in macOS, follow these steps:

Enter the following command in the Terminal window.
This starts the key generation process. When you execute this command, the ssh-keygen utility prompts you to indicate where to store the key.
Press the ENTER key to accept the default location. The ssh-keygen utility prompts you for a passphrase.
Type in a passphrase. You can also hit the ENTER key to accept the default (no passphrase). However, this is not recommended.

You will need to enter the passphrase a second time to continue.

After you confirm the passphrase, the system generates the key pair.

Your private key is saved to the id_rsa file in the .ssh directory and is used to verify the public key you use belongs to the same Triton Compute Service account.

Never share your private key with anyone!

Your public key is saved to the id_rsa.pub;file and is the key you upload to your Triton Compute Service account. You can save this key to the clipboard by running this:

Importing your SSH key

Generate An Ssh Key Linux

Now you must import the copied SSH key to the portal.

After you copy the SSH key to the clipboard, return to your account page.
Choose to Import Public Key and paste your SSH key into the Public Key field.
In the Key Name field, provide a name for the key. Note: although providing a key name is optional, it is a best practice for ease of managing multiple SSH keys.
Add the key. It will now appear in your table of keys under SSH.

Troubleshooting

You may see a password prompt like this:

This is because:

You did not enter the correct passphrase.
The private key on your Macintosh (id_rsa) does not match the public key stored with your Triton Compute Service account.
The public key was not entered correctly in your Triton account.
