Free Online Private and Public Key Generator Generate online private and public key for ssh, putty, github, bitbucket Save both of keys on your computer (text file, dropbox, evernote etc)!!! Sep 29, 2019  PuTTY Key Generator, also known by the PuTTY gen moniker, is a small yet efficient program that can generate RSA and DSA keys for use with the OpenSSH authorizedkeys file. It is a component of PuTTY and can be installed automatically with the Telnet client, but the chances are you would also see it incorporated in other third-party software. For a number of our services, we ask you to provide a private SSH key. For PuTTY users, this can cause an issue as we do not use the PuTTY-keygen format. Here is how you can convert your PuTTY key to OpenSSH format: Open your private key in PuTTYGen Top menu “Conversions”-”Export OpenSSH key”. Save the new OpenSSH key when prompted.

SSH keys are one of the most secure SSH authentication options. It is definitely more secure than the usual SSH password authentication. Therefore, it is highly recommended to use SSH Key authentication method for connections to your servers.

With password authentication, you can connect to your server from any location, you only need to fill in your password. However, if your password gets leaked, it is a major risk as anyone who knows your password will be able to get into the server.

SSH Key authentication only allows connections from clients whose key matches the one on the server. Basically, you generate a key pair (private key and public key). The private key is placed on your local machine and the public key is uploaded to the server. When connecting to the server, a validation of these two keys is made and if the key pair passes the validation you are allowed to connect. Of course, you can upload keys of multiple users so that you or other authorized users would be able to connect to the server from different computers.

As you can see this is a much safer connection method. In this tutorial, we will focus on Windows users who use PuTTY for connections to the server and show how to generate PuTTYSSH Keys. If you want to generate SSH Keys on Linux or Mac, see this tutorial.

What you’ll need

Before you begin this guide you’ll need the following:

  • Access to your Linux server / VPS
  • PuTTY and PuTTYgen installed on your computer (Download here)

Step 1 — Downloading PuTTYgen

Most of you have PuTTY installed on your computers already, however, to generate SSH Keys you also will need PuTTYgen.

  1. Download PuTTYgenhere
  2. You should be able to see this file downloaded:

No installation is required for PuTTYgen, it will run when you execute the file.

Step 2 — Generating your SSH Key pair

  1. Open up PuTTYgen by double clicking on the puttygen.exe file you have downloaded in Step 1.
  2. You should be able to see a window like this:
  3. Before generating your SSH Key pair, you can edit some settings, for example, key length, however, in most cases the default options will work just fine.
  4. Generate your SSH Key pair by clicking the Generate button.
  5. When the progress bar starts loading, move your mouse randomly across the area to load up the bar and generate your key pair.
  6. Your public SSH key will be displayed on the screen:
  7. For additional security it is highly recommended to think of a passphrase for your SSH key (However, you can also leave it empty):
  8. Save your private key to any desired location on your computer and name it anything you like.
  9. Save your public key to the same location on your computer and name it anything you like.

And that is it, you have generated your SSH Key pair. artrage 4.5 download The private key will stay on your computer (do not provide it to anyone) while your public key needs to be uploaded to the server you wish to connect to.

Step 3 — Setting up your private key on PuTTY

In order for the server to recognize your computer when connecting from PuTTY, you need to attach the private key to PuTTY.

  1. Open up PuTTY.
  2. Navigate to Connection -> SSH -> Auth in the left sidebar.
  3. Browse for your private key file in the field Private key for authentication
  4. Select the private key file with .ppk ending and click Open.

Step 4 – Adding public key to server

Lastly, you need to upload your public key to the server:

  1. On your local computer, open public key file (id_rsa.pub) you generated in Step 2 with any text editor and copy its contents (public key).
  2. Connect to your VPS using Putty. See this guide for detailed steps.
  3. If .ssh folder does not exist, create it together with authorized_keys file with the following command:
    mkdir ~/.ssh touch ~/.ssh/authorized_keys
  4. Secure SSH Key file by changing permissions:
    chmod 0700 ~/.ssh; chmod 0644 ~/.ssh/authorized_keys
  5. Open authorized_keys file with vim text editor:
    vim ~/.ssh/authorized_keys
  6. Press i key on your keyboard and right mouse button to paste the public key.
  7. Press Esc button and type in :x, hit Enter button. This command will save changes made to the file.

That is it, you can now use SSH keys instead of SSH password authentication to connect to your VPS.

Conclusion

You have learned how to generate PuTTY SSH Keys using PuTTYgen. This will make your connection to the server a lot more secure and convenient as you will not need to fill in the password each time. We recommend using this way of SSH authentication at all times and disable password authentication for good to completely secure your server. To find out how to completely disable SSH Password authentication on your server and use SSH Key authentication instead, follow this tutorial: How to disable SSH Password authentication on VPS.

On Windows, you can create SSH keys in many ways. This document explains how to use two SSH applications, PuTTY and Git Bash.

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.

PuTTY

PuTTY is an SSH client for Windows. You can use PuTTY to generate SSH keys. PuTTY is a free open-source terminal emulator that functions much like the Terminal application in macOS in a Windows environment. This section shows you how to manually generate and upload an SSH key when working with PuTTY in the Windows environment.

About PuTTY

PuTTY is an SSH client for Windows that you will use to generate your SSH keys. You can download PuTTY from www.chiark.greenend.org.uk.

When you install the PuTTY client, you also install the PuTTYgen utility. PuTTYgen is what you will use to generate your SSH key for a Windows VM.

This page gives you basic information about using PuTTY and PuTTYgen to log in to your provisioned machine. For more information on PuTTY, see the PuTTY documentation

Generating an SSH key

To generate an SSH key with PuTTYgen, follow these steps:

  1. Open the PuTTYgen program.
  2. For Type of key to generate, select SSH-2 RSA.
  3. Click the Generate button.
  4. Move your mouse in the area below the progress bar. When the progress bar is full, PuTTYgen generates your key pair.
  5. Type a passphrase in the Key passphrase field. Type the same passphrase in the Confirm passphrase field. You can use a key without a passphrase, but this is not recommended.
  6. Click the Save private key button to save the private key. You must save the private key. You will need it to connect to your machine.
  7. Right-click in the text field labeled Public key for pasting into OpenSSH authorized_keys file and choose Select All.
  8. Right-click again in the same text field and choose Copy.

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.

PuTTY and OpenSSH use different formats of public SSH keys. If the text you pasted in the SSH Key starts with —— BEGIN SSH2 PUBLIC KEY, it is in the wrong format. Be sure to follow the instructions carefully. Your key should start with ssh-rsa AAAA….

Once you upload your SSH key to the portal, you can connect to your virtual machine from Windows through a PuTTY session.

Git Bash

The Git installation package comes with SSH. Using Git Bash, which is the Git command line tool, you can generate SSH key pairs. Git Bash has an SSH client that enables you to connect to and interact with Triton containers on Windows.

To install Git:

  1. (Download and initiate the Git installer](https://git-scm.com/download/win).
  2. When prompted, accept the default components by clicking Next.
  3. Choose the default text editor. If you have Notepad++ installed, select Notepad++ and click Next.

When the installation completes, you may need to restart Windows.

Launching GitBash

To open Git Bash, we recommend launching the application from the Windows command prompt:

  1. In Windows, press Start+R to launch the Run dialog.
  2. Type C:Program FilesGitbinbash.exe and press Enter.

Generating SSH keys

First, create the SSH directory and then generate the SSH key pair.

One assumption is that the Windows profile you are using is set up with administrative privileges. Given this, you will be creating the SSH directory at the root of your profile, for example:

  1. At the Git Bash command line, change into your root directory and type.
