msi installation package and can be launch by going to the Windows Start menu → PuTTY (64-bit) → Pageant. Pageant is a PuTTY SSH authentication agent that holds the private keys in the memory. There is no need to do anything server on the server.īy clicking the 'Edit' button next to the 'Information' headline, you can additionally change the VM hostname and ISO image, choose boot devices, as well as insert your new SSH public key. If you need to change the public key you can do that from the Cloud Manager. Copying the Public Key to the ServerĬopy the public key you just generated to the BIP server order page and Continue. This is the key that you should add to your remote Linux server. It is advisable to save the file in the same directory where you saved the private key, using the same name the private key and “.txt” or “.pub” as a file extension. Open a text editor, paste the characters and save it. Right-click in the text field labeled “Public key for pasting into OpenSSH authorized_keys file” and select all characters by clicking “Select all”. Optionally, you can also save the public key, though it can be regenerated later by loading the private key. It’s common to use a descriptive name for the private key file. You can save the file in any directory as a “.ppk” file (PuTTY Private Key), but it is advisable to save in a place where you can easily find it. Save the private key by clicking the “Save private key” button. When a passphrase is set, it needs to be typed each time the private key is used. Otherwise, when generating a key for automation, it may be set without a passphrase.Ī passphrase adds an extra layer of security by protecting the private key from unauthorized use. It is recommended to use a passphrase when the private key files are intended for interactive use. If you don’t want to use a passphrase leave the fields blank. If you want set a passphrase, type it in the “Key passphrase” field and confirm the same passphrase in the “Confirm passphrase” field. Once the public key is generated it will be displayed in the “Key” block. As you move the pointer, the green progress bar will advance. You will be asked to move your mouse over the blank area of the Key section to generate some randomness. Optionally, you can change it to 4096.Ĭlick the “Generate” button to start the process of generating the new key pair. In the “Number of bits in a generated key” field leave the default value 2048, which is sufficient for most use cases. In the “Type of key to generate” block leave the default RSA. Launch PuTTYgen by double-clicking on its “.exe” file or by going to the Windows Start menu → PuTTY (64-bit) → PuTTYgen. To generate an SSH key pair on Windows using PuTTYgen, perform the following steps: The installation is simple, double-click on the installation package and follow the instructions. If you don’t have PuTTYgen installed, head over to the PuTTY download page and download the PuTTY installation package. PuTTYgen is available as a standalone executable file, and it is also a part of the PuTTY. PuTTYgen is an open-source utility that allows you to generate SSH keys for the most popular Windows SSH client PuTTY We will also show you how to set up an SSH key-based authentication and connect to your remote Linux servers without entering a password. This tutorial explains how to generate SSH keys on Windows with PuTTYgen. Using SSH keys is more secure and convenient than traditional password authentication. The two most popular mechanisms are passwords based authentication and public key-based authentication. Secure Shell (SSH) is a cryptographic network protocol used for a secure connection between a client and a server and supports various authentication mechanisms.
