Nov 26, 2018 If you prefer to use a GUI-based tool to create SSH keys, you can use the PuTTYgen key generator, included with the PuTTY download package. To create an SSH RSA key pair with PuTTYgen: Start PuTTYgen. Click Generate. By default PuTTYgen generates a 2048-bit SSH-2 RSA key. Move the mouse around in the blank area to provide randomness for the key. PuTTY does not natively support the private key format for SSH keys. PuTTY provides a tool named PuTTYgen, which converts keys to the required format for PuTTY. You must convert your private key (.pem file) into this format (.ppk file) as follows in order to connect to your instance using PuTTY.

SSH keys are a means of authenticating a user to an SSH server without using a password. Each “key” is actually a key pair consisting of a public key and a private key.
Keys are more secure than passwords because they are significantly more complex. While a password of eight characters is 72 bits long, SSH keys are often 2048 bits or longer. This longer string has many more possible permutations and therefore takes much more time to crack with a brute force attack.
If you require SSH access for multiple users, the use of SSH keys instead of individual logins can bypass many of the headaches involved in user management without violating PCI DSS. For details, see What are the advantages of using SSH keys to control access for multiple users?
Method
The process involves generating a pair of SSH key files containing a private key and a public key. The private key is known only to the user’s computer; the public key will be known to the server. Each key is useless without the other; therefore, only individuals with both the private and the public key can gain access to the server, and the private key is never revealed to the server.

Take special care to not lose the private key. A lost private key cannot be replicated; therefore, users cannot access the server until an administrator generates a new key pair. If you lose access to your server due to a lost key, contact our Support Team for assistance.
Though there are varying methods of generating SSH keys on machines using Windows, this one uses PuTTY Key Generator.
1: Generate the key
ATTENTION: The procedure and screen captures in this section reflect the latest version of PuTTY as of July 21, 2017 (0.70). If you use a different version, your interface may differ from the one pictured.
Download and install PuTTY.

ATTENTION: In Step 2 below, if you are using a pre-0.70 version of PuTTY, then select SSH-2 RSA radio button instead.
In the Type of key to generate section, select the RSA radio button.
In the Number of bits in a generated key field, type 4096.
Click Generate.
Move your mouse cursor in the area below the progress bar. When the progress bar is full, PuTTY generates your key pair.
- (Optional) Type a passphrase in the Key passphrase field. Repeat this passphrase in the Confirm passphrase field. If you plan to use your keys for automated processes; skip this step.
- Click the Save private key button to save the private key in a secure location. Use any name you like.
- Right-click in the text field labeled Public key for pasting into OpenSSH authorized_keys file and choose Select All.
- Right-click again in the same text field and choose Copy.
2: Upload the SSH key
Follow the procedure in How to reset your SSH password and add SSH keys in SiteWorx. In Step 3 of that article, paste the public SSH key you copied during Step 8 above section.

How to generate an SSH key in Windows 10
Monster hunter generations key quests hub. 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.

Generating SSH keys in a Windows environment used to be a convoluted process which required the installation of third-party tools. Since the Windows 10 April 2018 update, Windows has shipped with a preinstalled OpenSSH client, which means you can use ssh-keygen to generate SSH keys. Read on as we walk you through the entire process.
First, you’ll need to make sure OpenSSH is installed on your machine – if you upgraded from an earlier version of Windows 10, you may need to manually enable it. Launch the Settings app and click the “Apps” category. Next, click the “Manage optional features” link. If you don’t see “OpenSSH Client” in the list which appears, click the “Add a feature” button and install it. You might need to reboot your PC after the installation.
Once OpenSSH is installed, you’re ready to proceed. Open Command Prompt from the Start menu. Type “ssh-keygen” (without the quotes) into the terminal window and press enter. You’ll be prompted to confirm the save location. We recommend pressing enter to use the default location in your user directory. Otherwise, type a path to save the key in and then press enter.
You can now choose to add a passphrase (password) to the key. If you add one, you’ll need to supply it whenever you use the key. Either type a passphrase and press enter or press enter immediately to proceed without one.
Windows will now generate your RSA public/private key pair. The public key will be stored as “id_rsa.pub” in the directory you specified. Upload this key to any machines you need to SSH into. You can then open a connection using Windows’ built-in SSH client – type “ssh [email protected]” to connect and authenticate using your generated credentials.
