Windows git SSH authentication to GitHub. Follow @vlad. If you don’t have a SSH public/private key pair you can generate it using the puttygen utility. Passwordless SSH access. It is possible to configure your Pi to allow your computer to access it without providing a password each time you try to connect. To do this you need to generate an SSH key: Check for existing SSH keys. First, check whether there are already keys on the computer you are using to connect to the Raspberry Pi.

Overview

If you don't already have an SSH key, you must generate a new SSH key.If you're unsure whether you already have an SSH key, check for existing keys. If you don't want to reenter your passphrase every time you use your SSH key, you can add your key to the SSH agent, which manages your SSH keys and remembers your passphrase.

Adding your SSH key to the ssh-agent. Before adding a new SSH key to the ssh-agent to manage your keys, you should have checked for existing SSH keys and generated a new SSH key. When adding your SSH key to the agent, use the default macOS ssh-add command, and not an application installed by macports, homebrew, or some other external source.

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

Generate A Ssh Key For Github Windows 10

  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.

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

An article byA digital certificate or identity certificate is an electronic document which uses a digital signature to bind a public key with an identity, information such as the name of a person or an organization, their address, and so forth. The certificate can be used to verify that a public key belongs to an individual.In a typical public key infrastructure (PKI) scheme, the signature will be of a certificate authority (CA).

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.

    Sep 11, 2018  You can use Java key tool or some other tool, but we will be working with OpenSSL. To generate a public and private key with a certificate signing request (CSR), run the following OpenSSL command: openssl req –out certificatesigningrequest.csr -new -newkey rsa:2048 -nodes -keyout privatekey.key. Generate private key openssl online. Online CSR and Key Generator SSL.com’s public CSR and Key Generator is currently down for maintenance as part of our website’s redesign and update. Oct 09, 2019  PKCS#8 files are self-describing, and PKCS#8 private key files contain the public key, so a single command can output all the public properties for any private key. WARNING: By default OpenSSL's command line tool will output the value of the private key, even when you ask for it to output the public metadata; the -noout parameter suppresses this. Generating Public and Private Keys with openssl.exe To perform the following actions for Windows or Linux, you must have OpenSSL installed on your system. Generating the Private Key - Windows In Windows: 1. Open the Command Prompt (Start Programs Accessories Command Prompt). Navigate to the following folder.

  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

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.

Getting Help

Today’s post is for developers. If you use the Git version control system with a service such as GitHub, GitLab or Bitbucket to host and manage your projects source codes, you know that by default Git connects to remotes using the HTTPS protocol, which requires you to enter username and password every time you run a command such as git pull or git push.

Using the SSH protocol, you can connect and authenticate to servers to use their services. The three mentioned services allow Git to connect via SSH instead of HTTPS. Connecting with public key encryption dispenses typing username and password for every Git command.

You are going to see in this post how to use GitHub, GitLab and Bitbucket with SSH.

Make sure an SSH client in installed

In order to connect using the SSH protocol, an SSH client must be installed on your system. If you use openSUSE, it should be already installed by default.

Just to make sure, open the terminal and run:

That command should output the version number of the SSH client being used:

In case the system informs that the ssh command was not found, you can install the OpenSSH client running:

Check for existing SSH keys

To connect using the SSH protocol, you need an SSH key pair (one private and the other public). If you have never used SSH, you can safely skip this topic and move on to the next. If you have ever used SSH (for instance, to remotely access a server), probably you already have an SSH key pair, in which case you don’t need to generate a new key pair.

To see if existing SSH keys are present, run:

That command should list the contents of the ~/.ssh folder, in which the SSH client stores its configuration files:

If you receive an error that there is no ~/.ssh directory or there are no files in it, don’t worry: it means you haven’t created an SSH key pair yet. If that is the case, proceed to the next topic.

By default, public SSH keys are named:

  • id_dsa.pub;
  • id_ecdsa.pub;
  • id_ed25519.pub; or
  • id_rsa.pub.

Inside my ~/.ssh folder, I have an SSH key pair (id_rsa.pub is the public key and id_rsa is the private key) created a year ago (Jul 18 2018).

For security reasons, it is recommended that you generate a new SSH key pair at least once a year. If you already have an SSH key pair that was created more than a year ago, it is recommended that you proceed to the next topic.

If you already have an SSH key pair and want to reuse it, you can skip the next topic.

Generate a new SSH key pair

To generate a new SSH key pair, run the following command (replace your_email@example.com with your email address):

It asks you where to save the private key (id_rsa).

Press Enter to accept the default location.

If you already have a private key, it asks whether it should overwrite:

If that happens, type y and press Enter.

Then, enter and re-enter a passphrase (think of it as a kind of password):

The SSH key pair is created in ~/.ssh.

The whole interaction should look similar to the following:

Add the private SSH key to the ssh-agent

If you don’t want to type your passphrase each time you use your SSH keys, you need to add it to the ssh-agent, which is a program that runs in background while you are logged in to the system and stores your keys in memory.

To start the ssh-agent in background, run the following:

That command outputs the ssh-agentprocess identifier:

Then, add your SSH private key to the ssh-agent:

Type your passphrase and press Enter:

The command confirms that the private SSH key has been added to the ssh-agent:

Add the public SSH key to your account

Once you have an SSH key and have added it to the ssh-agent, you can set up connecting via SSH. Let’s see how to do that for each of the three servers: GitHub, GitLab and Bitbucket.

In all the three cases, the process is similar. Start by copying your public SSH key (~/.ssh/id_rsa.pub) file contents to the clipboard using the xclip command:

xclip is a command line utility that allows access to the graphical interface clipboard from the terminal. If it is not installed, you can install it running:

GitHub

Using a browser, go to the GitHub home page at github.com and sign in to your account.

In the upper-right corner of the page, click your profile photo, then click Settings:

In the user settings sidebar, click SSH and GPG keys. Then click New SSH key.

Fill in the Title field with a descriptive label for the new key (for example, the name of your computer) and paste your public key into the Key field. Finally, click Add SSH key:

Now the key appears in the list of SSH keys associated with your account:

GitLab

Using a browser, go to the GitLab home page at gitlab.com and sign in to your account.

In the upper-right corner of the page, click your profile photo, then click Settings:

Putty Generate Ssh Key For Github

In the User Settings sidebar, click SSH Keys.

Paste your public key in the Key field. Fill in the Title field with a descriptive label for the new key (for example, the name of your computer). Finally, click Add key:

Now the key appears in the list of SSH keys associated with your account:

Bitbucket

Using a browser, go to the Bitbucket home page at bitbucket.org and log in to your account.

In the lower-left corner of the page, click your profile photo, then click Bitbucket settings:

In the Settings sidebar, in the Security section, click SSH keys. Then, click Add key.

Fill in the Label field with a descriptive label for the new key (for example, the name of your computer) and paste your public key into the Key field. Finally, click Add key:

Now the key appears in the list of SSH keys associated with your account:

Test connecting via SSH

GitHub, GitLab and Bitbucket allow you to test whether SSH connection has been set up correctly before actually using it with Git.

GitHub

After you’ve added your SSH key to your GitHub account, open the terminal and run:

That command attempts an SSH remote access to GitHub.

If that is the first time you connect to GitHub via SSH, the SSH client asks you if it can trust the public key of the GitHub server:

Type yes and press Enter. The SSH client adds GitHub to the list of trusted hosts:

Once added to the list of known hosts, you won’t be asked about GitHub’s public key again.

As this remote access via SSH is provided by GitHub just for testing, not for actual use, the server informs that you have successfully authenticated and terminates the connection:

If you completed the test successfully, now you can use SSH with GitHub.

The whole interaction should look similar to the following:

Create New Ssh Key

GitLab

If you have added your SSH key to your GitLab account, the test is very similar:

If you completed the test successfully, now you can use SSH with GitLab.

Bitbucket

If you have added your SSH key to your Bitbucket account, the test is very similar:

If you completed the test successfully, now you can use SSH with Bitbucket.

Clone a repository using SSH

Now that we’ve got our SSH keys set up, let’s see how to clone a Git repository using SSH instead of HTTPS.

GitHub

At GitHub, go to a project’s repository, click Clone or download and copy the URL to clone the repository using SSH:

The URL of a GitHub repository looks like:

Open the terminal and run the git clone command passing the copied URL as argument.

Tip: to paste into the terminal, use Ctrl + Shift + V.

Note that now Git clones the repository without asking for a password:

GitLab

At GitLab, go to a project’s repository, click Clone and copy the URL to clone the repository using SSH:

Open the terminal and run the git clone command passing the copied URL as argument:

Note that now Git clones the repository without asking for a password.

Bitbucket

At Bitbucket, go to a project’s repository, click Clone and copy the command to clone the repository using SSH:

Note that, differently from GitHub and GitLab that present the URL, Bitbucket presents the entire git clone command, including the URL.

The URL of a Bitbucket repository looks like:

Open the terminal, paste and run the command you copied from Bitbucket:

Note that now Git clones the repository without asking for a password.

Reconfigure existing repositories to use SSH

The repositories we clone from now on using SSH will continue to use SSH for future Git commands such as git pull and git push. But existing local repositories, previously cloned with HTTPS, will continue to use HTTPS, unless we set them up to use SSH.

Ssh Key Generation Linux

To do that, open the terminal and change the current directory to a local repository.

List the existing remote repositories and their URLs with:

That command should output something like:

Change your remote repository’s URL with:

Generate A Ssh Key For Github Account

Run git remote -v once more to verify that the remote repository’s URL has changed:

Great. That done, Git will use SSH, instead of HTTPS, to synchronize that local repository with its remote equivalent.
