Ssh config windows identity file

The connection will usually prompt for a password, as an SSH connection should not be unprotected. These are the preferred way to setup an SSH connection. How do we tell our host configuration to use this file?

There are two new commands that we have introduced here. The IdentityFile and the IdentitiesOnly commands. First, we need to tell SSH where the key file is, in this case we have stored the file in the. Second, we have defined a tag named IdentitiesOnly. By default, SSH will walk through and try every identity file until it finds the right one. What if you have a scenario where you have opened an SSH connection to a target server, which then needs to make another SSH connection to a second server from that original target server?

When using key authentication with an SSH server, the SSH server and client compare the public key for a user name provided against the private key.

If the server-side public key cannot be validated against the client-side private key, authentication fails. Multi-factor authentication may be implemented with key pairs by entering a passphrase when the key pair is generated see user key generation below. During authentication the user is prompted for the passphrase, which is used along with the presence of the private key on the SSH client to authenticate the user.

Public keys have specific ACL requirements that, on Windows, equate to only allowing access to administrators and System. On first use of sshd, the key pair for the host will be automatically generated. By default the sshd service is set to start manually. To start it each time the server is rebooted, run the following commands from an elevated PowerShell prompt on your server:. If no algorithm is specified, RSA is used.

A strong algorithm and key length should be used, such as Ed in this example. To generate key files using the Ed algorithm, run the following from a PowerShell or cmd prompt on your client:. At this point, you'll be prompted to use a passphrase to encrypt your private key files. This can be empty but is not recommended. When you run this command, you can choose to save the keys to a location on your PC, and also set a password:.

This command will prompt you for the following information, and provide output similar to the following:. Navigate to the the folder where you stored your keys, you'll see a private key that has no extension and a public key that has a. Open the public key file with a text editor. The public key isn't sensitive. Here's what they look like:.
