The final steps are to copy the public key to the Client and append it to the authorization_keys file. ssh folder associated with the user account on the Host machine.ģ. The keys have now been generated and are stored in the. See more detail below in “Security Notes.”

It is highly recommended that you enter a passphrase unless you are setting up automated routines that require automatic login. In other words, you will be logged in automatically via the secure public / private key handshake that you are in the process of setting up. If you leave this field blank you will generate keys that do not prompt for a passphrase.

#SSH COPY KEY PASSWORD#

The passphrase can be thought of as a password for the private key - it serves as an extra layer of protection as described below. # Enter passphrase (empty for no passphrase): You will then be prompted for a passphrase that will be associated with this key. You should accept the suggested location unless you have reason to do otherwise. Also note that the actual suggested path may vary slightly depending your system. Note: “UserName” is the user account that you have logged into via SSH. # Enter file in which to save the key (/Users/UserName/.ssh/id_rsa): # Generating public/private rsa key pair. Execute the command and you should see the following output: Replace "server comment field" with a machine name, IP address, date, or task name so that you can easily identify where and why a given key was created.Ģ. It is helpful for identifying and managing keys within the authorized_keys file on the Client in the event that you have multiple key logins. It allows you to insert a comment that will appear in the authorized_keys file. # ssh-keygen -t rsa -C "server comment field" In terminal type the following at the command prompt: Login to the Host via SSH using your preferred terminal application and generate the public / private key pair. Let's setup SSH public key authentication between your home computer (hereafter referred to as the “ Host”) and your QNAP device (hereafter referred to as the “ Client").ġ. The below setup description assumes that you are able to run terminal or a terminal application like Putty, and that you are familiar with basic commands.

Transfer / append the public key to the authorized_keys file on the client.

Generate the needed Public and Private keys on the host.

Security of the system is predicated on the security of the private key. When authenticating, the host machine compares the public key to the private key in order to verify the veracity of the public key. The public key is derived from the private key. Public key authentication uses a pair of computer generated keys - one public and one private – to authenticate between a host and a client. It can also simplify the login process without compromising password security. In addition, public key authentication allows for automated login routines between machines, thus enabling a range of scripted jobs (think rsync or port tunneling).

See also my answer to Setting up public key authentication to Linux server from Windows (ppk private key).Public key authentication is considered a more secure methods of authenticating the Secure Shell than the simple password challenge routine, a method often broken by brute-force attacks.

If you need to append, you can download authorized_keys to the local machine, append it locally and re-upload it back.Īlternatively, you can setup the key from another Windows machine using (my) WinSCP client, with its Install Public Key into Server function. The above is basically, what ssh-copy-id does internally – Except that ssh-copy-id appends the authorized_keys, what plain sftp cannot do. Uploading id_rsa.pub to /C:/Users/martin/.ssh/authorized_keys Particularly if you have no key on the server registered yet, you can just upload the id_rsa.pub file as authorized_keys file: $ sftp password: If you want to do that from your local machine, you can do it using sftp. Also note that the location of the file for Administrators is overridden in the default sshd_config file to %ALLUSERSPROFILE%\ssh\administrators_authorized_keys.įor details, see my guide for Setting up SSH public key authentication on Win32-OpenSSH. ssh folder and the authorized_keys are set so that only a respective Windows account have a write access to the folder and the file and the account that runs the server have a read access.

Create authorized_keys file in the folder and add your public key to it.

ssh folder in your Windows account profile folder (typically in C:\Users\username\.ssh). I'm aware that you know that, but as there are subtle differences, when doing that on a Windows server, I'll mention it anyway for benefit of other readers. Ssh-copy-id script works only against *nix servers (or servers with *nix emulation), as it internally executes some *nix shell commands on the server (like exec, sh, umask, rm, mkdir, tail, cat, etc).
