This script is no longer maintained. Thanks for using it, I hope it was able to make life a little easier. I'm no longer using Windows and dragging out a VM or my old tower isn't on my list of to-do's these days.
This is a a lame PowerShell implementation of OpenSSH's ssh-copy-id
ssh-copy-id is a PowerShell script that uses ssh to log into a remote machine and append the
indicated identity file to that machine's ~/.ssh/authorized_keys file. By default, it installs the key(s) stored in $env:USERPROFILE\.ssh\id_rsa.pub.
CAUTION: This script is not declarative, it will append key(s) into authorized_keys that already exist. It may also be broken and overwrite your authorized_keys file.
This is published as a module in the PowerShell Gallery.
Install-Module -Name SSH-Copy-ID
Copy the SSH-Copy-ID folder to any one of the module folders that's returned by $Env:PSModulePath. Then import SSH-Copy-ID into your PowerShell session. This may be necessary if you can't install the module using the PowerShell Gallery.
PS> $Env:PSModulePath
C:\Users\n8tg\OneDrive\OneDrive Documents\WindowsPowerShell\Modules;C:\Program Files\WindowsPowerShell\Modules;C:\WINDOWS\system32\WindowsPowerShell\v1.0\Modules
PS> Copy-Item -Path ".\SSH-Copy-ID\" -Destination "C:\Users\n8tg\OneDrive\OneDrive Documents\WindowsPowerShell\Modules" -Recurse
PS> Import-Module SSH-Copy-ID
