How to Generate an SSH key in Windows 10

To generate an SSH key in Windows 10: Ensure the Windows 10 OpenSSH client is installed. Run “ssh-keygen” in Command Prompt and follow the instructions to generate your key.

  • Oct 22, 2019  A better solution would be to share the same set of SSH keys between Windows and WSL so that you have one set of keys for one machine. Setup SSH on Windows first. My recommendation is that you set up SSH on the Windows side first. Follow the instructions over on Github’s documentation to do this. It will walk you through generating the key.
  • PuTTYgen is a key generator tool for creating pairs of public and private SSH keys. It is one of the components of the open-source networking client PuTTY. Although originally written for Microsoft Windows operating system, it is now officially available for multiple operating systems including macOS, Linux.
  • The.pub file is your public key, and the other file is the corresponding private key. If you don’t have these files (or you don’t even have a.ssh directory), you can create them by running a program called ssh-keygen, which is provided with the SSH package on Linux/macOS systems and comes with Git for Windows.
  • Just download and install openSSH for windows. It is open source, and it makes your cmd ssh ready. A quick google search will give you a tutorial on how to install it, should you need it. After it is installed you can just go ahead and generate your public key if you want to put in on a server. You generate it by running: ssh-keygen -t rsa.

As you may already know, Windows 10 includes built-in SSH software - both a client and a server! This feature is available in the OS starting in version 1803. When the client option is installed, we can use it to generate a new SSH key.

On Windows machines, the freeware open-source software PuTTY is the de-facto standard when it comes to SSH and Telnet. With Windows 10, Microsoft has finally listened to its users after years of them requesting an SSH client and server. By including an OpenSSH implementation, the value of the OS increases.

The provided SSH client is similar to the Linux client. At first glance, it appears to support the same features as its *NIX counterpart. It is a console app, so you should be able to start it from the command prompt.

To proceed, you need to enable the OpenSSH Client feature. Check out the following text:

Assuming that you have it installed, you can do the following. /how-i-can-generate-key-for-the-csr.html.

To Generate an SSH key in Windows 10,

  1. Open a new command prompt.
  2. Type ssh-keygen and hit the Enter key.
  3. The app will ask for the save location, offering C:usersyour user name.sshid_rsa by default.
  4. Next, you will be prompted to enter a passphrase. You can just hit the Enter key to skip it.
  5. Finally, you will see the fingerprint for your key and SHA256. The default algorithm is RSA 2048.

You are done. Your public key will be saved to the id_rsa.pub file, by default it is C:usersyour user name.sshid_rsa.pub. You can now upload this file to the target machine you want to access with SSH. Do not share your private SSH key (id_rsa) unless you know what you are doing!

SSH supports a number of other public key algorithms using with keys, such as:

  • rsa - this is a classic algorithm based on the difficulty of factoring large numbers. Recommended keys size - 2048 or above.
  • dsa - yet another legacy algorithm based on the difficulty of computing discrete logarithms. It is no longer recommended.
  • ecdsa - a new Digital Signature Algorithm standarized by the US government, using elliptic curves. It supports 256, 384, and 521 key sizes.
  • ed25519 - this algorithm is the latest options included in OpenSSH. Certain software lacks support for it.

You can specify the algorithm using the -t option and change the key size using the -b switch. Some examples:

That's it.
