In order to properly configure a Windows client for authenticating via SSH keys, the public key (.PUB) file must be transferred to the client device's.ssh directory and stored in the authorized. 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.
Further extend Microsoft’s implementation of OpenSSH in Windows 10 by generating your own secure keys.
The use of OpenSSH is ubiquitous with secured access to client devices over a network. The purpose of SSH is straight-forward: To securely encapsulate the management traffic between two end-points, in this case using the server-client model for authentication.
While SSH may be enabled to work over clients, which are joined to the same domain, say using Active Directory credentials, this is not possible when attempting to communicate to devices such as network switches or routers, which are not natively part of any domain infrastructure. Instead, these devices and Linux-based clients use a public/private key pair to verify the user attempting to connect to the client and perform authentication before providing remote access.

In this article, we will use this use case as it is often considered to be a more secure method of obtaining access, which lends itself seamlessly to Windows and non-Windows devices alike. By generating and managing SSH key pairs, IT will be able to remotely connect to clients in a secure manner while ensuring confidentiality and non-repudiation for each user, using a unique key pair tied to the individual’s Windows login account for secure storage.
Install the OpenSSH module for PowerShell
1. Log in to the Windows computer with an admin-level account and launch PowerShell with admin privileges.
2. Enter the following cmdlet to install the OpenSSH module. If this is the first time the module has been installed on the device, you may be prompted to download and install some additional tools. Type “Y” to allow the tools to be installed.
Install-Module -Force OpenSSHUtils
3. Next, enter the cmdlet to start the ssh-agent service for securely storing privately generated SSH keys.
Start-Service ssh-agent
4. Last, enter the cmdlet to start the sshd service, which will generate the first pair of host keys automatically.
Start-Service sshd
Note: By default, the OpenSSH Server app in not installed, so it must first be installed. Also, the ssh-agent service is set to Disabled and must be changed before the cmdlets above will work. Host keys are stored at the %HOMEDRIVE%ProgramDatassh directory.

Generate user key pair
1. In PowerShell, change directories to the path above where the SSH keys are stored, then enter the cmdlet below to being generating the key pair.
ssh-keygen
2. In order to generate a unique set of key pairs and store them, you will be prompted to provide a directory where the key pair will be stored, or you may press enter to choose the default location provided.
3. Next, you’ll be prompted to choose a passphrase to encrypt the key pair with. While providing a passphrase is optional, it is highly advised to enter one as it serves the secondary purpose of acting as a form of two-factor authentication when utilizing the key pair to establish remote connections.
4. Once the process is completed, two files will be generated alongside the SHA256 fingerprint, and the key’s random art image will be displayed on-screen and should look like this (Figure A):
Copying the public key securely
The OpenSSH tools include the SCP and SFTP utilities to make transferring keys completely secure. In order to properly configure a Windows client for authenticating via SSH keys, the public key (.PUB) file must be transferred to the client device’s .ssh directory and stored in the authorized_keys text file.
1. Begin the process by executing the following command in PowerShell to create the .ssh directory within the user’s profile folder.
ssh [email protected] mkdir C:Usersusername.ssh
2. Using the SCP utility, enter the following command to securely copy the public key from the server to the client device.
scp C:Usersusername.sshid_rsa.pub [email protected]:C:Usersusername.sshauthorized_keys
3. Lastly, modify the ACL on the authorized_keys file on the server by entering the following command.
ssh —% [email protected] powershell -c $ConfirmPreference = ‘None’; Repair-AuthorizedKeyPermission C:Usersusername.sshauthorized_keys

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:
- Open the PuTTYgen program.
- For Type of key to generate, select SSH-2 RSA.
- Click the Generate button.
- Move your mouse in the area below the progress bar. When the progress bar is full, PuTTYgen generates your key pair.
- 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.
- 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.
- Right-click in the text field labeled Public key for pasting into OpenSSH authorized_keys file and choose Select All.
- 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.
- 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.
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
https://iwantpowerful540.weebly.com/adobe-premiere-pro-cs6-family-key-generator.html. , 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:
- (Download and initiate the Git installer](https://git-scm.com/download/win).
- When prompted, accept the default components by clicking Next.
- Choose the default text editor. If you have Notepad++ installed, select Notepad++ and click Next.
- Select to Use Git from the Windows Command Prompt and click Next.
- Select to Use OpenSSL library and click Next.
- Select to Checkout Windows-style, commit Unix-style line endings and click Next.
- Select to Use MinTTY (The default terminal of mYSYS2) and click Next.
- Accept the default extra option configuration by clicking Install.
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: Netscaler internal failure in ssl cert key generation tool.
- In Windows, press Start+R to launch the Run dialog.
- 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:
- At the Git Bash command line, change into your root directory and type.
- Change into the .ssh directory
C:Usersjoetest.ssh
- To create the keys, type:
- When prompted for a password, type apassword to complete the process. When finished, the output looks similar to:
Uploading an SSH key
To upload the public SSH key to your Triton account:
- Open Triton Service portal, select Account to open the Account Summary page.
- From the SSH section, select Import Public Key.
- Enter a Key Name. Although naming a key is optional, labels are a best practice for managing multiple SSH keys.
- Add your public SSH key.
