In Windows 10, finding your SSH public key is a necessary skill, especially if you want to connect securely to remote servers or share your public key for access to certain services. To locate your SSH public key, you’ll need to navigate to where it’s stored on your computer. The process involves using Windows’ built-in terminal to search your system for the key file.

In this section, I’ll guide you through finding your SSH public key on a Windows 10 machine. By following these simple steps, you’ll be able to easily locate and view your key.

Step 1: Open Command Prompt or PowerShell

To get started, open the Command Prompt or PowerShell on your Windows 10 computer.

You can do this by typing “cmd” or “PowerShell” in the Start menu search bar and hitting Enter. Both Command Prompt and PowerShell will work for this task, but PowerShell tends to offer more features.

Step 2: Navigate to the .ssh Directory

Next, navigate to the .ssh directory by typing cd %userprofile%.ssh and pressing Enter.

This command jumps straight to the .ssh folder within your user profile, where your SSH keys are usually stored. If you receive an error, the .ssh directory might not exist yet, indicating you need to generate a key.

Step 3: List the Files

Once you’re in the .ssh directory, list all files by typing dir in Command Prompt or ls in PowerShell.

You should see a list of files, one of which will likely be named id_rsa.pub or id_ecdsa.pub. These are common names for SSH public key files. If no such file exists, you might need to generate a new SSH key pair.

Step 4: Display the Public Key

To view your public key, type type id_rsa.pub in Command Prompt or cat id_rsa.pub in PowerShell.

This command displays the contents of the id_rsa.pub file, which is your public key. The text that appears is what you would share with others to allow them to verify your identity securely.

Step 5: Copy the Key

Finally, copy the displayed key by selecting the text and using Ctrl + C.

Ensure you select the entire key, as partial keys won’t work. You can then paste it wherever you need, such as on a GitHub account or remote server configuration.

After you complete these steps, you should be able to access your SSH public key. This key can be shared safely with others or used to configure your access to servers and services. Remember, never share your private key, as doing so can compromise your security.

This article will provide a comprehensive guide on how to find your SSH public key on Windows 11. This guide will cater to users of all skill levels, from beginners to more experienced users, ensuring that everyone can securely connect to remote servers.

Understanding SSH Keys

Before diving into the steps to find your SSH public key, let’s briefly cover what SSH keys are and why they are essential.

What are SSH Keys?

SSH keys are a pair of cryptographic keys that provide a secure way to access servers. The pair consists of a private key and a public key. The private key is kept secret and is stored on your local machine, while the public key can be shared with anyone.

Why Use SSH Keys?

• Security: SSH keys are more secure than using passwords. The complexity of the keys makes it nearly impossible for attackers to compromise.
• Convenience: Once set up, SSH keys allow you to log in to remote servers without needing to enter a password each time.
• Automation: SSH keys facilitate the automation of scripts and commands that need to access remote servers securely.

Prerequisites

To find your SSH public key on Windows 11, you must have SSH installed. Thankfully, Windows 11 comes with OpenSSH client pre-installed. If you are unsure whether it’s installed or not, you can check by following these simple steps:

1. Open the Start Menu and type in «Settings.»
2. Go to Apps and then select Optional features.
3. Scroll down to see if «OpenSSH Client» is listed. If it’s not there, you may need to install it.

Finding Your SSH Public Key

Step 1: Open Windows Terminal or Command Prompt

To find your SSH keys, you’ll need to use the Windows Terminal or Command Prompt. Here’s how to proceed:

1. Click on the Start Menu.
2. Type “Windows Terminal” or “Command Prompt” in the search bar.
3. Right-click on the application and select Run as administrator. This ensures that you have all necessary permissions.

Step 2: Navigate to the .ssh Directory

SSH keys are typically stored in a hidden directory within your user profile called .ssh. To navigate to this directory, you need to use a command:

1. Type the following command and press Enter:

   cd ~/.ssh

This command changes the current directory to the .ssh folder under your user profile.

Step 3: Verify the Existence of SSH Keys

Inside the .ssh directory, you will likely find file names like id_rsa and id_rsa.pub. The first file (id_rsa) is your private key, and the second (id_rsa.pub) is your public key.

To list the contents of the .ssh directory, use the command:

dir

This command will display all files in the directory. Look for files that match the conventional naming scheme:

id_rsa
id_rsa.pub

Step 4: View Your Public Key

Once you confirm that the id_rsa.pub file exists, you can view its content, which is your public key. To do this, enter the following command:

type id_rsa.pub

The output will display your public key in a long string format. It will start with ssh-rsa followed by a series of characters and will typically end with your username and hostname.

If your public key file has a different name, replace id_rsa.pub with the appropriate filename.

Generating SSH Keys (If Not Found)

If you can’t find any SSH keys, you can create a new pair. Here’s how you can generate SSH keys in Windows 11:

Step 1: Generate the Key Pair

1. In the Windows Terminal or Command Prompt, type the following command:

   ssh-keygen -t rsa -b 4096 -C "[email protected]"

2. Press Enter to execute the command. You will be prompted to choose a location to save the private key. You can simply hit Enter to save it in the default location (C:UsersYourUserName.sshid_rsa).

3. If you want to set a passphrase for added security, you can do so; otherwise, just hit Enter again.

4. After this process completes, you will see confirmation that your keys have been generated.

Step 2: Locate Your Public Key

Now that you’ve generated your keys, you will again find your public key under the .ssh directory:

1. Navigate to the .ssh directory using the command:

   cd ~/.ssh

2. Use the command to display your public key:

   type id_rsa.pub

How to Use Your SSH Public Key

   ssh username@remote_host

If the SSH keys are correctly set up, you should be logged in without being prompted for a password.

Common Issues and Troubleshooting

While working with SSH keys, you might encounter some common issues. Here are a few tips on how to troubleshoot them:

Issue 1: Permission Denied (Public Key)

This message indicates that the SSH server did not accept your public key. Ensure that:

• Your public key is added to the ~/.ssh/authorized_keys file on the remote server.
• The permissions of the .ssh directory and the authorized_keys file are correctly set (the directory should be 700 and the file 600).

Issue 2: SSH Agent Not Running

If you find that your SSH key is not automatically being used, ensure that the SSH agent is running:

1. Start the SSH agent in the background with the command:

   eval "$(ssh-agent -s)"

2. Add your SSH private key to the agent with the command:

   ssh-add ~/.ssh/id_rsa

Issue 3: Compatibility Issues with Other Applications

If you’re using applications like Git or other tools that utilize SSH, ensure that they are configured to use the system’s SSH client or, if necessary, specify the SSH executable path in the application’s settings.
