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.
Use the ssh-keygen command to generate a public/private authentication key pair. Authentication keys allow a user to connect to a remote system without supplying a password. Keys must be generated for each user separately. If you generate key pairs as the root user, only the root can use the keys.
About Terminal
- Generating SSH keys in a Windows environment used to be a convoluted process which required the installation of third-party tools. Since the Windows 10 April 2018 update, Windows has shipped with a.
- Ssh-agent.exe stores private keys used for public key authentication; ssh-add.exe adds private keys to the list allowed by the server; ssh-keyscan.exe aids in collecting the public SSH host keys from a number of hosts; sftp.exe is the service that provides the Secure File Transfer Protocol, and runs over SSH; scp.exe is a file copy utility that.
Terminal is the terminal emulator which provides a text-based command line interface to the Unix shell of macOS.
$ ssh-keygen -lf ided25519.pub 256 SHA256:PO2bk6B. It is unlikely that the recommend ED25519 SSH key is only 256 bits long. Linux ubuntu key ssh-keys openssh. Ssh-keygen is a tool for creating new authentication key pairs for SSH. Such key pairs are used for automating logins, single sign-on, and for authenticating hosts. SSH Keys and Public Key Authentication The SSH protocol uses public key cryptography for authenticating hosts and users.
To open the macOS Terminal, follow these steps:
- 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-keygenutility prompts you to indicate where to store the key.Press the ENTER key to accept the default location. The
ssh-keygenutility 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! |

Ssh Genkey Git
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
Now you must import the copied SSH key to the portal.
Ssh Gen Key Windows
- 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.
Ssh Copy Id
Troubleshooting
You may see a password prompt like this:
Ssh Genkey
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.

Right in the portal, you can easily create Docker containers, infrastructure containers, and hardware virtual machines.
In order to use the Terminal to create instances, set up triton and CloudAPI as well as the triton-docker commandline tool.
