How to Find My SSH Public Key on Windows 10: A Step-by-Step Guide

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.

Finding Your SSH Public Key in Windows 10

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.

Tips for Finding Your SSH Public Key in Windows 10

• Ensure your SSH key exists by checking for id_rsa.pub or id_ecdsa.pub in the .ssh directory.
• If the key isn’t found, generate one using ssh-keygen in your terminal.
• Use PowerShell for more advanced features and better command support.
• Keep a backup of your SSH keys in a secure location for easy retrieval.
• Always be cautious and never share your private SSH key.
