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

2. Generate Ssh Key Windows

Key generation with PuTTY. To generate a key pair with the PuTTY key generator, simply run puttygen.exe and click the Generate button in the window that appears. You will be asked to move the mouse and press keys to improve the random number generation at the heart of SSH security. Ssh-keygen -i -f puttygenkey opensshkey then you can copy the contents of opensshkey in to.ssh/authorizedkeys just as with a normal SSH key. The -i option is the one that tells ssh-keygen to do the conversion. The -f option tells it where to find the key to convert. This works for unencrypted keys. The public key is unencrypted, but the.

How to convert SSH keypairs generated using PuTTYgen (Windows) into key-pairs used by ssh-agent and Keychain (Linux). Nope, there is - I know this much that the key formats used by PuttyGen and ssh-agent are different, and they have to be converted explicitly - see Kaleb's detailed answer below. The most common way to make a key on. PuTTYgen is a SSH Tools App for Windows 10. It is your ultimate tool for creating SSH key for Putty. Used to generate pairs of public and private keys, these keys are used not only for putty, but also for PSCP, Pageant and Plink. Provides RSA key for use with the SSH-1 and SSH-2 protocols. Nov 15, 2017  In this video, I show you how to setup SSH Keys in Windows with PuttyGen. This allows you to connect to your linux server without having to authenticate with a password. I hope you guys Enjoy. The PuTTY SSH client for Microsoft Windows does not share the same key format as the OpenSSH client. Therefore, it is necessary to create a new SSH public and private key using the PuTTYgen tool or convert an existing OpenSSH private 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. Windows 7 ultimate activation key generator 2018.

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.

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

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.

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

3. To create the keys, type:

4. 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.

Obtaining and Starting PuTTYgen

PuTTYgen originates from PuTTY and is also part of the PuTTY installation package. It can be downloaded here: https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

When you run PuTTYgen you will see a window where you have two choices: Generate, to generate a new public/private key pair, or Load to load in an existing private key.

Generating a New Key

• First, you need to select which type of key you want to generate, and also select the strength of the key.
• Then press the Generate button, to actually generate the key.
• Once you have generated the key, select a comment field and a passphrase.
• Now you’re ready to save the private key to disk; press the Save private key button.

Your key pair is now ready for use. You may also want to copy the public key to your server, either by copying it out of the Public key for pasting into authorized_keys file box, or by using the Save public key button. However, you don’t need to do this immediately; if you want, you can load the private key back into PuTTYgen later and the public key will be available for copying and pasting again.

Selecting the Type of Key

Before generating a key pair using PuTTYgen, you need to select which type of key you need. PuTTYgen currently supports these types of key:

• An RSA key for use with the SSH-2 protocol.
• A DSA key for use with the SSH-2 protocol.
• An ECDSA (elliptic curve DSA) key for use with the SSH-2 protocol.
• An Ed25519 key (another elliptic curve algorithm) for use with the SSH-2 protocol.
• An RSA key for use with the SSH-1 protocol.

The SSH-2 protocol supports more than one key type. The types supported by WinSCP are RSA, DSA, ECDSA, and Ed25519.

The SSH-1 protocol only supports RSA keys; if you will be connecting using the SSH-1 protocol, you must select the last key type or your key will be completely useless.

Selecting the Size (Strength) of the Key

The Number of bits input box allows you to choose the strength of the key PuTTYgen will generate.

For RSA, 2048 bits should currently be sufficient for most purposes.

For ECDSA, only 256, 384, and 521 bits are supported. (ECDSA offers equivalent security to RSA with smaller key sizes.)

For Ed25519, the only valid size is 256 bits.

Puttygen Ssh Key

The Generate Button

Once you have chosen the type of key you want, and the strength of the key, press the Generate button and PuTTYgen will begin the process of actually generating the key.

First, a progress bar will appear and PuTTYgen will ask you to move the mouse around to generate randomness. Wave the mouse in circles over the blank area in the PuTTYgen window, and the progress bar will gradually fill up as PuTTYgen collects enough randomness. You don’t need to wave the mouse in particularly imaginative patterns (although it can’t hurt); PuTTYgen will collect enough randomness just from the fine detail of exactly how far the mouse has moved each time Windows samples its position.

When the progress bar reaches the end, PuTTYgen will begin creating the key. The progress bar will reset to the start, and gradually move up again to track the progress of the key generation. It will not move evenly, and may occasionally slow down to a stop; this is unfortunately unavoidable, because key generation is a random process and it is impossible to reliably predict how long it will take.

When the key generation is complete, a new set of controls will appear in the window to indicate this.

The Key Fingerprint Box

The Key fingerprint box shows you a fingerprint value for the generated key. This is derived cryptographically from the public key value, so it doesn’t need to be kept secret; it is supposed to be more manageable for human beings than the public key itself.

Generate Ssh Key Windows

The fingerprint value is intended to be cryptographically secure, in the sense that it is computationally infeasible for someone to invent a second key with the same fingerprint, or to find a key with a particular fingerprint.

Setting a Passphrase for Your Key

The Key passphrase and Confirm passphrase boxes allow you to choose a passphrase for your key. The passphrase will be used to encrypt the key on disk, so you will not be able to use the key without first entering the passphrase.

When you save the key, PuTTYgen will check that the Key passphrase and Confirm passphrase boxes both contain exactly the same passphrase, and will refuse to save the key otherwise.

If you leave the passphrase fields blank, the key will be saved unencrypted. You should not do this without good reason; if you do, your private key file on disk will be all an attacker needs to gain access to any machine configured to accept that key. If you want to be able to passwordless log in without having to type a passphrase every time, you should consider using Pageant so that your decrypted key is only held in memory rather than on disk.

Under special circumstances you may genuinely need to use a key with no passphrase; for example, if you need to run an automated batch script that needs to make an SSH connection, you can’t be there to type the passphrase. In this case we recommend you generate a special key for each specific batch script (or whatever) that needs one, and on the server side you should arrange that each key is restricted so that it can only be used for that specific purpose. The documentation for your SSH server should explain how to do this (it will probably vary between servers).

Choosing a good passphrase is difficult. /ssl-key-generate-with-password.html. Just as you shouldn’t use a dictionary word as a password because it’s easy for an attacker to run through a whole dictionary, you should not use a song lyric, quotation or other well-known sentence as a passphrase. If you want your passphrase to make grammatical sense, this cuts down the possibilities a lot and you should use a longer one as a result.

Do not forget your passphrase. There is no way to recover it.

Saving Your Private Key to a Disk File

Once you have generated a key, set a comment field and set a passphrase, you are ready to save your private key to disk.

Press the Save private key button. PuTTYgen will put up a dialog box asking you where to save the file. Select a directory, type in a file name, and press Save.

Saving Your Public Key to a Disk File

RFC 4716 specifies a standard format for storing SSH-2 public keys on disk. Some SSH servers (such as ssh.com’s) require a public key in this format in order to accept authentication with the corresponding private key. (Others, such as OpenSSH, use a different format)

To save your public key in the SSH-2 standard format, press the Save public key button in PuTTYgen. PuTTYgen will put up a dialog box asking you where to save the file. Select a directory, type in a file name, and press Save.

You will then probably want to copy the public key file to your SSH server machine.

If you use this option with an SSH-1 key, the file PuTTYgen saves will contain exactly the same text that appears in the Public key for pasting box. This is the only existing standard for SSH-1 public keys.
