I want to generate two SSH public key on both of these machines. One is for my GitHub account and the other one is for my GitLab account. I have used the following commands to generate the public SSH key which is perfectly work in my Linux machine but not in the Windows machine. Commands: Step 1: Generate SSH Key.

In our guide we will learn about creating.
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,
- 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.

There are three main ways to generate a public key in Windows. We've tried them all with Windows 7, but given the PuTTY tools are most popular, they are documented first. Whichever method you choose, email your generated key to your designated manager and they will notify you when your account has been created. Note, if you have multiple keys because you have multiple machines, or perhaps you have different keys for different software, send them all to us - we can set you up with as many keys as you want bound to your Code Enigma account.
PuTTY
This is a Free Open Source Software (FOSS) solution for Windows that allows Windows users to generate SSH keys and use them to access Linux servers via an SSH connection.
[1] Download and run the PuTTY 'Installer' from this page:
[2] Generate a private and public key pair:
- Go to the Windows Start menu -> All Programs -> PuTTY and open PuTTYgen
- Click the 'Generate' button and PuTTYgen will ask you to make some random movement with your mouse until it has enough random data to generate a secure key for you
- Click the 'Save private key' button and save the resulting file somewhere safe and only accessible by you!
[3] Export Public key to the Linux server:
In the grey box at the top, entitled 'Public key for pasting into OpenSSH authorized_keys file', there will be a string of nonsense. Copy all of this string into an email and send it to us, as per the opening instruction on this page.
That's it, you're done!
Git Bash
This is a light-weight terminal client for using Git from the command line on Windows. It's a sort of scaled down version of CygWin, and one of the nice things about it is it permits normal 'Terminal' access to Linux servers.
Generate Ssh Key In Windows Machine For Free
[1] Download and run the latest version from this page:
The installer will open msysGit when it completes, follow the instruction to create a shortcut:
[2] Generate a private and public key pair:
Follow steps 1 and 2 of the GitHub instructions found here:
At step 3, use the 'clip' command as instructed, but paste the result into an email and send it.
Bitvise
If none of the above works, there's also Bitvise, which is not FOSS, but is freely available for personal use, and even individual use within an organisation, so it's a good and legal option.
[1] Download the Bitvise SSH client software:
[2] Generate a private and public key pair:
- click the link titled 'User keypair manager' in the Login tab;
- click the button [Generate New ...];
- choose ssh-rsa and 1024bits;
- you can enter passphrase or leave it empty
- click the button [Generate]
This passphrase is not sent to the remote host, and it is only used to protect your private key. Otherwise, anyone who has access to your private key can authenticate to your account automatically.
[3] Export Public key to the Linux server:
- Go to the 'User keypair manager';
- click the keypair in the slots;
- click the button [Export];
- chose 'Export public key' and 'OpenSSH format';
- click the button [Export];
The result should look something like:
Email just this public part to Code Enigma, as per instructions.
