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.

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.
I am trying to generate a new SSH key on my windows computer using command prompt. I have installed Cygwin and added its path to use linux commands through command prompt. Now ls is listing me the inner folders. But ssh is still nor working. On trying to generate SSH key using the command ssh-keygen -t rsa -C 'emailid'. 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.
To proceed, you need to enable the OpenSSH Client feature. Check out the following text:
License key. Assuming that you have it installed, you can do the following.
To Generate an SSH key in Windows 10,
- Open a new command prompt.
- Type
ssh-keygen
and hit the Enter key. - The app will ask for the save location, offering
C:usersyour user name.sshid_rsa
by default. - Next, you will be prompted to enter a passphrase. You can just hit the Enter key to skip it.
- 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.
