Script to Get Hash Value of a Directory


Vadims Podans has posted a script for PowerShell here which can be used to generate the hash value of a folder containing multiple files.

Simply copy and paste this function in PowerShell:

function Get-FolderHash ($folder) { dir $folder -Recurse | ?{!$_.psiscontainer} | %{[Byte[]]$contents += [System.IO.File]::ReadAllBytes($_.fullname)} $hasher = [System.Security.Cryptography.SHA1]::Create() [string]::Join("",$($hasher.ComputeHash($contents) | %{"{0:x2}" -f $_})) }

Then enter the command:

Get-FolderHash "C:\foofolder"

A single SHA1 hash value will be generated for the entire folder.
