In asymmetric cryptography, the public and private key can also be used to create a digital signature. A digital signature assures that the person sending the message is who they claim to be. Typically, we use the recipient’s public key to encrypt the data and the recipient then uses their private key to decrypt the data. To generate the public/private key pair, enter this in the Command Prompt: ssh-keygen At the first prompt, “Enter file in which to save the key,” press Enter to save it in the default location.
Lets say you have a private/public key pair that you use to login to your server via SSH and you lose the public key, either it was deleted or corrupt and you don’t want to have to regenerate a new pair what options do you have? In this post I will demonstrate how to regenerate a public key from the corresponding private key that you still have.
Generate public key and store into a file
It is a simple one liner command to generate a public key from a private key, so lets say our private key is named ‘user@myserver.key’ and we want to generate the public key and name it ‘authorized_keys’. Below is the command to do this.
2 4 6 | user@workstation:~$rsync-avz--remove-source-files authorized_keys user@remote_server_ip_address:/home/user/.ssh/authorized_keys test sent95bytes received43bytes92.00bytes/sec user@workstation:~$ |
At this point our public key file is on our server where it is supposed to be in our users ‘.ssh’ directory.
Set proper permissions for public key
Lastly we will need to make sure our permissions are set properly on our public key to prevent anyone else tampering with it. We should give our key file RW, R, R permissions, below is the command to properly set permission on the key.
Terminal is the terminal emulator which provides a text-based command line interface to the Unix shell of macOS.
Generate Private And Public Key
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.
Generate Rsa Public Private Key
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.
- 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.
What are my next steps?
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.
