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

Use Openssl To Generate Key Pair
Openssl Generate Csr
Openssl Generate Key Pair Windows 1

Run it on your local computer to generate a 2048-bit RSA key pair, which is fine for most uses. Ssh-keygen The utility prompts you to select a location for the keys. By default, the keys are stored in the /.ssh directory with the filenames idrsa for the private key and idrsa.pub for the public key.

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.

As you can see, it’s very easy to generate SSH keys on Windows these days. Basically, the ssh-keygen command does all the work. If you find it difficult to understand how to add the public key to the server, look up your provider’s documentation. They always have a page that describes, in detail, how to do this. Mar 29, 2016 Generate Client and Server Keystores We start by creating a keystore for the server. Execute the following command in a terminal. This command generates a 2048-bit RSA key pair, which is valid for 365 days and stored under the alias server in the server. SSH keys are a way to identify trusted computers, without involving passwords. The steps below will walk you through generating an SSH key and adding the public key to the server. Step 1: Check for SSH Keys. First, check for existing SSH keys on your computer. Open Git Bash, Cygwin, or Terminal, etc. Apr 09, 2020 Generate a CA private key file using a utility (OpenSSL, cfssl etc) Create the CA root certificate using the CA private key. Server Certificate Creation Process. Generate a server private key using a utility (OpenSSL, cfssl etc) Create a CSR using the server private key. Generate the server certificate using CA key, CA cert and Server CSR. Nov 12, 2019 KMS client setup keys. Computers that are running volume licensed editions of Windows Server, Windows 10, Windows 8.1, Windows Server 2012 R2, Windows 8, Windows Server 2012, Windows 7, Windows Server 2008 R2, Windows Vista, and Windows Server 2008 are, by default, KMS clients with no additional configuration needed.

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, it is in the wrong format. Be sure to follow the instructions carefully. Your key should start with ssh-rsa AAAA….

Use Openssl To Generate Key Pair

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:

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.

Openssl Generate Csr

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.

When Triton finishes the adding or uploading process, the public SSH key appears in the list of SSH keys.

What are my next steps?

Adding SSH keys to agent.
Set up the Triton CLI and CloudAPI on Windows.
Set up the Triton CLI and CloudAPI.
Create an instance in the Triton Service Portal.
Set up the triton-docker command line tool.

To sign an assembly with a strong name, you must have a public/private key pair. This public and private cryptographic key pair is used during compilation to create a strong-named assembly. You can create a key pair using the Strong Name tool (Sn.exe). Key pair files usually have an .snk extension.

Note

In Visual Studio, the C# and Visual Basic project property pages include a Signing tab that enables you to select existing key files or to generate new key files without using Sn.exe. In Visual C++, you can specify the location of an existing key file in the Advanced property page in the Linker section of the Configuration Properties section of the Property Pages window. The use of the AssemblyKeyFileAttribute attribute to identify key file pairs was made obsolete beginning with Visual Studio 2005.

Create a key pair

To create a key pair, at a command prompt, type the following command:

sn –k <file name>

In this command, file name is the name of the output file containing the key pair.

The following example creates a key pair called sgKey.snk.

If you intend to delay sign an assembly and you control the whole key pair (which is unlikely outside test scenarios), you can use the following commands to generate a key pair and then extract the public key from it into a separate file. First, create the key pair:

Next, extract the public key from the key pair and copy it to a separate file:

Once you create the key pair, you must put the file where the strong name signing tools can find it.

When signing an assembly with a strong name, the Assembly Linker (Al.exe) looks for the key file relative to the current directory and to the output directory. When using command-line compilers, you can simply copy the key to the current directory containing your code modules.
