Nov 10, 2011  How to Generate A Public/Private SSH Key Linux By Damien – Posted on Nov 10, 2011 Nov 18, 2011 in Linux If you are using SSH frequently to connect to a remote host, one of the way to secure the connection is to use a public/private SSH key so no password is transmitted over the network and it can prevent against brute force attack.

  • Sep 08, 2016  Use the crypto key generate dsa command to generate DSA key pairs for your router. DSA keys are generated in pairs—one public DSA key and one private DSA key. If your router already has DSA keys when you issue this command, you are warned.
  • After you add a private key password to ssh-agent, you do not need to enter it each time you connect to a remote host with your public key. Generating authentication key pairs. Use the ssh-keygen command to generate authentication key pairs as described below. Provide a passphrase, for example “password”, when creating the key pairs.

How to Generate an SSH key in Windows 10

As you may already know, Windows 10 includes built-in SSH software - both a client and a server! This feature is available in the OS starting in version 1803. When the client option is installed, we can use it to generate a new SSH key.

On Windows machines, the freeware open-source software PuTTY is the de-facto standard when it comes to SSH and Telnet. With Windows 10, Microsoft has finally listened to its users after years of them requesting an SSH client and server. By including an OpenSSH implementation, the value of the OS increases.

The provided SSH client is similar to the Linux client. At first glance, it appears to support the same features as its *NIX counterpart. It is a console app, so you should be able to start it from the command prompt.

To proceed, you need to enable the OpenSSH Client feature. Check out the following text:

Assuming that you have it installed, you can do the following.

To Generate an SSH key in Windows 10,

  1. Open a new command prompt.
  2. Type ssh-keygen and hit the Enter key.
  3. The app will ask for the save location, offering C:usersyour user name.sshid_rsa by default.
  4. Next, you will be prompted to enter a passphrase. You can just hit the Enter key to skip it.
  5. Finally, you will see the fingerprint for your key and SHA256. The default algorithm is RSA 2048.

You are done. Your public key will be saved to the id_rsa.pub file, by default it is C:usersyour user name.sshid_rsa.pub. You can now upload this file to the target machine you want to access with SSH. Do not share your private SSH key (id_rsa) unless you know what you are doing!

SSH supports a number of other public key algorithms using with keys, such as:

  • rsa - this is a classic algorithm based on the difficulty of factoring large numbers. Recommended keys size - 2048 or above.
  • dsa - yet another legacy algorithm based on the difficulty of computing discrete logarithms. It is no longer recommended.
  • ecdsa - a new Digital Signature Algorithm standarized by the US government, using elliptic curves. It supports 256, 384, and 521 key sizes.
  • ed25519 - this algorithm is the latest options included in OpenSSH. Certain software lacks support for it.

You can specify the algorithm using the -t option and change the key size using the -b switch. Some examples:

That's it.

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

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:

  1. In Finder, choose Utilities from the Applications folder.
  2. Find Terminal in the Utilities listw.
  3. 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:

Generate Dsa Key Without Prompt Code

  1. Enter the following command in the Terminal window. Sftp generate public key windows.

    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.

Generate Dsa Key Without Prompt Key

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.

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.

In order to use the Terminal to create instances, set up triton and CloudAPI as well as the triton-docker commandline tool.
