Next to Load an existing private key file, click the Load button.If you need to see the public key in the right format after the private key has been saved: You can click Save public key as well, but take note: The format PuTTYGen uses when it saves the public key is incompatible with the OpenSSH authorized_keys files used for SSH key authentication on Linux servers. We strongly recommend using a passphrase, but you can press ENTER to bypass this prompt. If you have not entered a passphrase, you will be asked to confirm that you want to save the key without one. You can name your key whatever you’d like, and the extension. When you’re done, click the Save private key button and select a secure location to keep it. You’ll need to provide your passphrase every time you use this key (unless you use SSH agent software that stores the decrypted key). This improves security by preventing someone who gains access to your private key from using it without also knowing the passphrase. Next, you’ll be prompted to enter a passphrase for your SSH key. Be sure to scroll within the text area so you copy the entire key. Copy this into your clipboard now if you plan to add it to your DigitalOcean account or to servers. When the key is generated, you’ll see the public key displayed in a text box. This randomness, known as entropy, is used to create keys in a secure fashion so that other people can’t reproduce them. You might be prompted to “generate some randomness by moving the mouse over the blank area”. When you’re ready, click the Generate button on the right-hand side. However, Fedora 33’s new encryption requirements will not accept the default RSA algorithm, so choose ECDSA or another supported algorithm when creating a key for use with Fedora 33. You can customize the Parameters at the bottom if you like, but the default values are appropriate in most situations. The key generation program looks similar to this: Next, install it on your local computer by double clicking it and using the installation wizard.Īfter the programs are installed, start the PuTTYgen program through your Start Menu or by tapping the Windows key and typing puttygen. msi file in the Package files section at the top of the page, under MSI (‘Windows Installer’). To create and use SSH keys on Windows, you need to download and install both PuTTY, the utility used to connect to remote servers through SSH, and PuTTYgen, a utility used to create SSH keys. Each Droplet you create is a new server you can use, either standalone or as part of a larger, cloud-based infrastructure. DigitalOcean Droplets are Linux-based virtual machines (VMs) that run on top of virtualized hardware.
