Generating a new SSH key Open the terminal. Paste the text below, substituting in your GitHub email address. When you're prompted to 'Enter a file in which to save the key,' press Enter. At the prompt, type a secure passphrase. For more information. May 23, 2019  By default, the ssh-keygen command will create two files in the user's.ssh folder: idrsa and idrsa.pub. Idrsa (without an extension) is the private key file, while idrsa.pub contains the public key. With the key created, next you must start the SSH Agent service which manages private keys locally and coordinates their usage in authentication. Sep 26, 2019  Generating an SSH key. To generate an SSH key with PuTTYgen, follow these steps: Open the PuTTYgen program. For Type of key to generate, select SSH-2 RSA. Click the Generate button. Move your mouse in the area below the progress bar. When the progress bar is full, PuTTYgen generates your key pair. Type a passphrase in the Key passphrase field. SSH public-key authentication uses asymmetric cryptographic algorithms to generate two key files – one 'private' and the other 'public'. The private key files are the equivalent of a password, and should protected under all circumstances. If someone acquires your private key, they can log in as you to any SSH server you have access to.

How to Generate an SSH key in Windows 10

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.

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 Key Generate For Windows10

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.
