Generating Keys

If you are going to connect to a remote host computer using public-key authentication, you will have to generate a key pair before connecting.

Public-key authentication is based on the use of digital signatures. Each user creates a pair of key files. One of these key files is the user's public key, and the other is the user's private key. The server knows the user's public key, and only the user has the private key.

When the user tries to authenticate, the server checks for matching public keys and sends a challenge to the user end. The users are authenticated by signing the challenge using their private keys.

Remember that your private key file is used to authenticate you. Never expose your private keys. If anyone else can access your private key file, they can attempt to log in to the remote host computer as you, and claim to be you. Therefore it is extremely important that you keep your private key file in a secure place and make sure that no one else has access to it.

Do not use public-key authentication on a computer that is shared with other users. Generate keys only on your personal computer that no one else can access!

Also note that if you are using the Windows roaming profiles functionality, your personal settings will be replicated with the roaming profile server. If you store your private keys in the default location (under the profile folder of your Windows user account) your private keys may be susceptible to a malicious user listening to the network traffic. Therefore the User Settings folder should not be a directory that is used in profile roaming.

In order to use public-key authentication, you must first generate your own key pair. You can generate your own key files with the help of a built-in Key Generation wizard.

You can also import existing keys on the Keys page of the Settings dialog. See Section Managing Keys.

On Windows, you can create SSH keys in many ways. This document explains how to use two SSH applications, PuTTY and Git Bash. Free serial key epson l120 wic key.

Ssh-keygen is a tool for creating new authentication key pairs for SSH. This is a tutorial on its use, and covers several special use cases. There are a multiplicity of articles on the web about setting up SSH on Google compute engine for Linux instances but a lack of ones describing how to successfully generate them for a windows insta. The default ssh authentication for GCE instance is public key authentication and not password based. Moreover, for security reasons, most of the standard Google images do not provide the ability to connect directly as root. I am using an SSH key that is set in the Google Cloud Console and that key is associated with the username. My guess is that Google Compute Engine is using this 'meta-data' and reconfiguring the folder permissions to match that of the user associated with the SSH key. Is there any way to disable this 'auto-reset'? Mar 08, 2016  SSH Into Google Cloud Compute Engine Instance Using Secure Shell Client last. Zone for db1 detected as us-central1-a. WARNING: You don't have an ssh key for Google Compute Engine. Instance creator and any users that were added using the –authorizedsshkeys flag or the metadata sshKeys value are automatically.

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

Engine

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.

Ssh Key Generation Windows

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.
  4. Select to Use Git from the Windows Command Prompt and click Next.
  5. Select to Use OpenSSL library and click Next.
  6. Select to Checkout Windows-style, commit Unix-style line endings and click Next.
  7. Select to Use MinTTY (The default terminal of mYSYS2) and click Next.
  8. Accept the default extra option configuration by clicking Install.

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

Launching GitBash

Google Computer Engine Auto Ssh Key Generation Prevented

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.
  1. Change into the .ssh directory C:Usersjoetest.ssh

  2. To create the keys, type:
  1. 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:

  1. Open Triton Service portal, select Account to open the Account Summary page.
  2. From the SSH section, select Import Public Key.
  3. Enter a Key Name. Although naming a key is optional, labels are a best practice for managing multiple SSH keys.
  4. Add your public SSH key.

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