Generate Publick Key From Mac Keychain

Jun 26, 2019 An alternative to password authentication is public key authentication, in which you generate and store on your computer a pair of cryptographic keys and then configure your server to recognize and accept your keys. Using key-based authentication offers a range of benefits: Key-based login is not a major target for brute-force hacking attacks. What is Keychain Access on Mac? Keychain Access is a macOS app that stores your passwords and account information and reduces the number of passwords you have to remember and manage. When you access a website, email account, network server, or other password-protected item, you may be given the option to remember or save the password. It generates a new public/private keypair when you create a CSR in Keychain Access. The name of the key will be what you entered in the 'Common Name' field when generating the CSR. If you would like to generate a new CSR from an existing key, I do not believe this can be done entirely within Keychain Access. ARCHIVED: In Mac OS X, how do I create a new Keychain?

Locating your public key. Once you have created your key GPG Keychain has both, your public and secret key. Your own key shows in bold and is listed as sec/pub while your friends public keys show as pub in the Type column. Double click any entry to open detailed information about that key. For your own sec/pub key you can renew, add or remove an expiry date for example.

Keychain Access is a macOS app that stores your passwords and account information and reduces the number of passwords you have to remember and manage. When you access a website, email account, network server, or other password-protected item, you may be given the option to remember or save the password. Keychain is where your keys and identities (entities within Termius) are stored. Connecting to a host with a key requires adding the key, by importing or generating it, to the keychain. After adding a key or identity, you can choose them in the host settings.

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.

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.

Mac Keychain Access

To generate SSH keys in macOS, follow these steps:

  1. 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.

  2. Press the ENTER key to accept the default location. The ssh-keygen utility prompts you for a passphrase.

  3. 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

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

  1. After you copy the SSH key to the clipboard, return to your account page.
  2. Choose to Import Public Key and paste your SSH key into the Public Key field.
  3. 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.
  4. Add the key. It will now appear in your table of keys under SSH.
