Installing OpenSSH for Windows

In this post we will look at how to install Microsoft official version of OpenSSH for Windows. This guid was prepared for Windows 10.

Download the OpenSSH Windows binaries (https://github.com/PowerShell/Win32-OpenSSH/releases/) and extract it into C:\Program Files\OpenSSH
Open terminal as administrator and go to the folder:
[pre class="brush:bash"]cd C:\Program Files\OpenSSH[/pre]
Install sshd and ssh-agent services
[pre class="brush:bash"]powershell.exe -ExecutionPolicy ByPass -File .\install-sshd.ps1[/pre]
Setup SSH host keys (generate all the 'host; keys that sshd expects when it starts)
[pre class="brush:bash"].\ssh-keygen.exe -A[/pre]
Securing the SSH host keys

Start service ssh-agent (Control Panel -> Administrative Tools -> Services -> ssh-agent -> Start the service)
Download PsExec.exe (https://technet.microsoft.com/en-us/sysinternals/pxexec.aspx?f=255&MSPPError=-2147217396)
Launch terminal as administrator and enter the following command after going into the folder [pre class="brush:bash"]psexec.exe -i -s cmd.exe[/pre]
A new cmd window will open and enter the following commands to encrypt the keys (after going into the OpenSSH folder) [pre class="brush:bash"]ssh-add ssh_host_dsa_key
ssh-add ssh_host_rsa_key
ssh-add ssh_host_ecdsa_key
ssh-add ssh_host_ed25519_key
[/pre]
Host keys are now securely stored by the ssh-agent, private key files can be now removed

If you are going to be doing key-based authentication, run the following setup the key-auth package [pre class="brush:bash"]Powershell.exe -ExecutionPolicy ByPass -File .\install-sshlsa.ps1[/pre]
