Once the service is started, use the ssh-add component to add the new key into the local key store. With the key created, next you must start the SSH Agent service which manages private keys locally and coordinates their usage in authentication. Id_rsa (without an extension) is the private key file, while id_rsa.pub contains the public key. ssh-keygenīy default, the ssh-keygen command will create two files in the user's. This provides an additional layer of security. If you choose to use a passphrase, you'll be prompted to enter it to decode the private key every time you connect to the server with SSH. You can also protect the private key with a passphrase. When prompted, you can press enter to accept the defaults, or enter a custom path and name for the key files. Next, switch to a regular (non-admin) PowerShell session and use the ssh-keygen command to generate a new key pair. This will need to be done with a PowerShell window run as Administrator Add-WindowsCapability -Online -Name OpenSSH.Client~~~~0.0.1.0

Follow this process using PowerShell from the client computer you will be connecting fromįirst, if not already installed, install the OpenSSH client. The OpenSSH client capability in Windows includes the tools required to do so. The first step to using key-based authentication is to generate a key pair - a set of matching public and private keys. Configuring the Client and Generating a Key Pair Since the private key is considerably more complex than a password, this offers greater security over basic username/password authentication.
When the client attempts to connect, the client and server communicate to ensure the private key that the client has matches an allowed public key on the server side.
Instead, a private key stored on the client is paired with a public key stored on the server. In case you aren't already familiar with key-based authentication, it is a way of authenticating to remote servers without using a password. If you are familiar with key-based auth for SSH to Linux servers, this process is very similar. If you want to enable key-based auth instead, you have to go through some additional steps to generate the keys and place them in the correct locations.

The previous post leaves off with SSH enabled and working with username and password authentication. If you haven't yet installed and configured SSH, start by reading that first. This is a follow up to a previous post: Getting Started with SSH on Windows Server 2019.
