In this post I want to give a quick outline of how to setup Powershell Core (Microsoft’s cross-platfrom version of Powershell) to work with git and ssh.

While you can simply install Git for Windows and work with Git Bash, personally I quite like Powershell Core, because it is more tightly integrated with Windows and Azure. I will not cover working with CMD, because in my personal opinion, CMD offers, to put it mildly, a suboptimal user experience …

So, let’s get started:

• Install Git for Windows
• Install Powershell Core
• Run Powershell as Admin with: Set-ExecutionPolicy -Scope LocalMachine -ExecutionPolicy RemoteSigned -Force

This will allow all users to execute scripts that have been remotely signed, i.e. are from the web. Optionally, you can also use "-Scope CurrentUser" if you only want to enable remotely signed scripts for your user account.

• Open Powershell and type git to check that it is on your PATH and do the same with ssh. If it is not on your PATH, you need to add it before you continue.
• Setup Posh-Git by running the following in Powershell:

Set-PSRepository -Name PSGallery -InstallationPolicy Trusted
PowerShellGet\Install-Module posh-git -Scope CurrentUser -AllowPrerelease -Force

## Update an existing version:
PowerShellGet\Update-Module posh-git

## Add PoshGit to all PowerShell hosts (console, ISE, etc)
Add-PoshGitToProfile -AllHosts

Now that we have Posh-Git up and running, let’s generate a public/private key-pair:

• Open Powershell and run ssh-keygen -t rsa -b 4096 -C "your_email@example.com" and press enter to save to the default location. You can set a password as well.
• Now you need to add your key to ssh-agent. I used Git Bash to start ssh-agent with eval $(ssh-agent -s), because Windows 10 now also ships with ssh and Git wants to use its own bundled ssh binaries, while posh-git starts the Windows ssh binaries (see Windows 10 version 1803 broke my git SSH if you want to use the ssh binaries shipped with Windows instead of with Git)
• Run ssh-add ~/.ssh/id_rsa to add your key to ssh-agent.

Now you should be ready to use git+ssh with Powershell:)
