function Compare-FileToHash {
<#
.SYNOPSIS
Compare-FileToHash - Compares a file to a given hash and returns a boolean of whether they match or not
.DESCRIPTION 
This function will compare a file to a given hash (in string format) and 
returns the boolean $true or $false depending on whether the hashes match. 

Supported algorithms are all those supported by Get-FileHash.
.EXAMPLE
Compare-FileToHash -expectedHash F683E63A08F385F52E86990CEB62CF1374A23373 -algorithm SHA1 -Path $env:SYSTEMROOT\System32\shell32.dll

  Param(
    $expectedHash,
    $algorithm="MD5",
    $Path
    )

  $actualHash = (Get-FileHash -Path $Path -Algorithm $algorithm).Hash

  New-Object -TypeName PSObject -Property @{
      "Path" = $Path
      "ExpectedHash" = $expectedHash
      "ActualHash" = $actualHash
      "Match" = if ($expectedHash -eq $actualHash) { $true } else { $false }
  }
  
}

Awesome little snippet tweaked it a bit, to keep items in order and also add a default -simple that just does true / false

param(
        [Parameter(Mandatory)]
        [ValidateNotNullOrEmpty()]
        [string]$expectedHash,

        [Parameter(Mandatory=$false)]
        [ValidateNotNullOrEmpty()]
        [string]$algorithm = "MD5",

        [Parameter(Mandatory)]
        [ValidateNotNullOrEmpty()]
        [string]$path,

        [Parameter(Mandatory=$false)]
        [bool]$simple = $true
    )

    $actualHash = (Get-FileHash -Path $path -Algorithm $algorithm).Hash
    
    $Results=@()
    
    switch ($simple) {
        $true {
            if ($expectedHash -eq $actualHash) { Write-Host $true -ForegroundColor Green } else { Write-Host $false -ForegroundColor Red }
        }
        default {
        $hashProps = [ordered]@{
            "Path" = $path
            "Actual Hash" = $actualHash
            "Expected Hash" = $expectedHash
            "Matches" = if ($expectedHash -eq $actualHash) { $true } else { $false }
        }

        $Results += New-Object -TypeName PSObject -Property $hashProps

        $Results
       
        }
    }

I like it...all except the use of Write-Host, which I don't like! Thanks for the contribution :)
