If you don't have an existing public and private key pair, or don't wish to use any that are available to connect to GitHub, then generate a new SSH key. If you see an existing public and private key pair listed (for example idrsa.pub and idrsa) that you would like to use to connect to GitHub, you can add your SSH key to the ssh-agent. When you clone your github repository you can select http and ssh url for github project. You can clone with HTTPS, SSH or Subversion. I think you should select ssh to work with ssh authentication. Check your cloned git project's config. There is a remore url that you can change to ssh url. Create your SSH keys with the ssh-keygen command from the bash prompt. This command will create a 2048-bit RSA key for use with SSH. This command will create a 2048-bit RSA key for use with SSH.

An SSH key is an access credential for the SSH (secure shell) network protocol. This authenticated and encrypted secure network protocol is used for remote communication between machines on an unsecured open network. SSH is used for remote file transfer, network management, and remote operating system access. The SSH acronym is also used to describe a set of tools used to interact with the SSH protocol.

SSH uses a pair of keys to initiate a secure handshake between remote parties. The key pair contains a public and private key. The private vs public nomenclature can be confusing as they are both called keys. It is more helpful to think of the public key as a 'lock' and the private key as the 'key'. You give the public 'lock' to remote parties to encrypt or 'lock' data. This data is then opened with the 'private' key which you hold in a secure place.

How to Create an SSH Key

SSH keys are generated through a public key cryptographic algorithm, the most common being RSA or DSA. At a very high level SSH keys are generated through a mathematical formula that takes 2 prime numbers and a random seed variable to output the public and private key. This is a one-way formula that ensures the public key can be derived from the private key but the private key cannot be derived from the public key.

SSH keys are created using a key generation tool. The SSH command line tool suite includes a keygen tool. Most git hosting providers offer guides on how to create an SSH Key.

Generate an SSH Key on Mac and Linux

Both OsX and Linux operating systems have comprehensive modern terminal applications that ship with the SSH suite installed. The process for creating an SSH key is the same between them.

1. execute the following to begin the key creation

This command will create a new SSH key using the email as a label

Create

2. You will then be prompted to 'Enter a file in which to save the key.'
You can specify a file location or press “Enter” to accept the default file location.

3. The next prompt will ask for a secure passphrase.
A passphrase will add an additional layer of security to the SSH and will be required anytime the SSH key is used. If someone gains access to the computer that private keys are stored on, they could also gain access to any system that uses that key. Adding a passphrase to keys will prevent this scenario.

At this point, a new SSH key will have been generated at the previously specified file path.

4. Add the new SSH key to the ssh-agent

The ssh-agent is another program that is part of the SSH toolsuite. The ssh-agent is responsible for holding private keys. Think of it like a keychain. In addition to holding private keys it also brokers requests to sign SSH requests with the private keys so that private keys are never passed around unsecurly.

Before adding the new SSH key to the ssh-agent first ensure the ssh-agent is running by executing:

Once the ssh-agent is running the following command will add the new SSH key to the local SSH agent.

The new SSH key is now registered and ready to use!

Generate an SSH Key on Windows

Windows environments do not have a standard default unix shell. External shell programs will need to be installed for to have a complete keygen experience. The most straight forward option is to utilize Git Bash. Once Git Bash is installed the same steps for Linux and Mac can be followed within the Git Bash shell.

Windows Linux Subsystem

Modern windows environments offer a windows linux subsystem. The windows linux subsystem offers a full linux shell within a traditional windows environment. If a linux subsystem is available the same steps previously discussed for Linux and Mac can be followed with in the windows linux subsystem.

Summary

SSH keys are used to authenticate secure connections. Following this guide, you will be able to create and start using an SSH key. Git is capable of using SSH keys instead of traditional password authentication when pushing or pulling to remote repositories. Modern hosted git solutions like Bitbucket support SSH key authentication.

Overview

OSG Connect requires SSH-key-based logins. You need to followa two-step process to set up the SSH key to your account.

  1. Generate a SSH key pair.

  2. Add your public key to the submit host by uploading it toyour OSG Connect user profile (via the OSG Connect website).

After completing the process, you can log in from a local computer(your laptop or desktop) to the OSG Connect login node assignedusing either ssh or an ssh program like Putty -- see below formore details on logging in.

Create Github Ssh Key

NOTE: Please do not edit the authorized keys file on the login node.

Step 1: Generate SSH Keys

We will discuss how to generate a SSH key pair for two cases:

  • 'Unix' systems (Linux, Mac) and certain, latest versions of Windows
  • Older Windows systems

Please note: The key pair consist of a private key and a public key. You will upload thepublic key to OSG Connect, but you also need to keep a copy of the private key to log in!
You should keep the private key on machines that you havedirect access to, i.e. your local computer (your laptop or desktop).

Unix-based operating system (Linux/Mac) or latest Windows 10 versions

Open a terminal on your local computer and run the following commands:

The last command will produce a prompt similar to

Unless you want to change the location of the key, continue by pressing enter.Now you will be asked for a passphrase. Enter a passphrase that you will beable to remember and which is secure:

When everything has successfully completed, the output should resemble thefollowing:

The part you want to upload is the content of the .pub file (~/.ssh/id_rsa.pub)

Windows, using Putty to log in

If you can connect using the ssh command within the Command Prompt (Windows 10 build version 1803 and later), please follow the Mac/Linux directions above. If not,continue with the directions below.

  1. Open the PuTTYgen program. You can download PuttyGenhere: PuttyGen Download Page,scroll down until you see the puttygen.exe file.

  2. For Type of key to generate, select RSA or 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. Youcan 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.

Step 2: Add the public SSH key to login node

To add your public key to the OSG Connect log in node:

  1. Go to www.osgconnect.net and sign in with the institutional identity you used when requesting an OSG Connect account.

  2. Click 'Profile' in the top right corner.

  3. Click the 'Edit Profile' button located after the user information in the left hand box.

  4. Copy/paste the public key which is found in the .pub file into the 'SSH Public Key' text box.The expected key is a single line, with three fields looking something likessh-rsa ASSFFSAF.. user@host. If you used the first set of key-generatinginstructions it is the content of ~/.ssh/id_rsa.pub and for the second (usingPuTTYgen), it is the content from step 7 above.

  5. Click 'Update Profile'

The key is now added to your profile in the OSG Connect website. This will automaticallybe added to the login nodes within a couple hours.

Logging In

After following the steps above to upload your key and it's been a few hours, you shouldbe able to log in to OSG Connect.

Determine which login node to use

Before you can connect, you will need to know which login node your account is assigned to. You can findthis information on your profile from the OSG Connect website.

  1. Go to www.osgconnect.net and sign in with your CILogin.

  2. Click 'Profile' in the top right corner.

  3. The assigned login nodes are listed in the left side box. Make note of the address ofyour assigned login node as you will use this to connect to OSG Connect.

For Mac, Linux, or newer versions of Windows

Open a terminal and type in:

It will ask for the passphrase for your ssh key (if you set one) and then youshould be logged in.

For older versions of Windows

Ssh Key Github

On older versions of Windows, you can use the Putty program to log in.

  1. Open the PutTTY program. If necessary, you can download PuTTY from the website here PuTTY download page.

  2. Type the address of your assigned login node as the hostname (see 'Determine which login node to use' above).

  3. In the left hand menu, click the '+' next to 'SSH' to expand the menu.

  4. Click 'Auth' in the 'SSH' menu.

  5. Click 'Browse' and specify the private key file you saved in step 5 above.

  6. Click 'Open' and provide your passphrase when prompted to do so.
