get-filehash

Usando a Função GET-filehash eu tive um resultado diferente do mesmo script, é normal?

function Get-SHA256 {
    param (
        $Filename
    )
    $Conteudo = Get-Content $Filename
    $filebyte = [System.Text.Encoding]::UTF8.GetBytes($Conteudo)

    $sha256 = New-Object System.Security.Cryptography.SHA256Managed
    $hash256 =  $sha256.ComputeHash($filebyte)
    $fullex = New-Object System.Text.StringBuilder
    foreach ($byte in $hash256) {
        $hex = $byte.ToString("X2")
        $fullex.Append($hex) > $null
    }
    $fullex.ToString()
}

$arquivo = "C:\temp\Scripts\hs-fuctions.ps1"
$hashDoArquivo = Get-SHA256 $arquivo

Write-host "O hash do arquivo $arquivo eh $hashDoArquivo" -BackgroundColor Red -ForegroundColor Yellow
