Moreover, they are both generated with the same code: openssl (the command-line tool) is a wrapper around OpenSSL (the library), and OpenSSH actually uses OpenSSL (the library) for its cryptographic operations, including key pair generation.

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.

Add your SSH private key to the ssh-agent and store your passphrase in the keychain. If you created your key with a different name, or if you are adding an existing key that has a different name, replace idrsa in the command with the name of your private key file.
Generating Your SSH Public Key. Many Git servers authenticate using SSH public keys. In order to provide a public key, each user in your system must generate one if they don’t already have one. This process is similar across all operating systems. First, you should check to make sure you don’t already have a key.

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, 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:

Openssl Windows Generate Ssh Key Linux

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.

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.

< Cryptography

Download and install the OpenSSL runtimes. If you are running Windows, grab the Cygwin package.

OpenSSL can generate several kinds of public/private keypairs.RSA is the most common kind of keypair generation.^[1]

Other popular ways of generating RSA public key / private key pairs include PuTTYgen and ssh-keygen.^[2]^[3]

Generate an RSA keypair with a 2048 bit private key[edit]

Execute command: 'openssl genpkey -algorithm RSA -out private_key.pem -pkeyopt rsa_keygen_bits:2048'^[4] (previously “openssl genrsa -out private_key.pem 2048”)

e.g.

Make sure to prevent other users from reading your key by executing chmod go-r private_key.pem afterward.

Extracting the public key from an RSA keypair[edit]

Execute command: 'openssl rsa -pubout -in private_key.pem -out public_key.pem'

e.g.

A new file is created, public_key.pem, with the public key.

Keylemon 323. Keylemon 3.2.3 gold license key. More Samsung Kies 3 3.2.16084.2. Samsung Electronics Co., Ltd. 38.9MB - Freeware - Kies 3 is a media library designed for Samsung products. It is compatible with MP3 players, smartphones tablets, and more. It also has other features like the ability to view HD videos or play music directly from the library.

It is relatively easy to do some cryptographic calculations to calculate the public key from the prime1 and prime2 values in the public key file.However, OpenSSL has already pre-calculated the public key and stored it in the private key file.So this command doesn't actually do any cryptographic calculation -- it merely copies the public key bytes out of the file and writes the Base64 PEM encoded version of those bytes into the output public key file.^[5]

Viewing the key elements[edit]

Openssl Windows Generate Ssh Key Id

Execute command: 'openssl rsa -text -in private_key.pem'

All parts of private_key.pem are printed to the screen. This includes the modulus (also referred to as public key and n), public exponent (also referred to as e and exponent; default value is 0x010001), private exponent, and primes used to create keys (prime1, also called p, and prime2, also called q), a few other variables used to perform RSA operations faster, and the Base64 PEM encoded version of all that data.^[6](The Base64 PEM encoded version of all that data is identical to the private_key.pem file).

Password-less login[edit]

Often a person will set up an automated backup process that periodically backs up all the content on one 'working' computer onto some other 'backup' computer.

Because that person wants this process to run every night, even if no human is anywhere near either one of these computers, using a 'password-protected' private key won't work -- that person wants the backup to proceed right away, not wait until some human walks by and types in the password to unlock the private key.Many of these people generate 'a private key with no password'.^[7]Some of these people, instead, generate a private key with a password,and then somehow type in that password to 'unlock' the private key every time the server reboots so that automated toolscan make use of the password-protected keys.^[8]^[3]
