function Get-HashCheck { 
  [CmdletBinding()] 
  Param([Parameter(ValueFromPipeline)]$o)
  process {
    Write-Output "File: $([System.IO.FileInfo]::new($o.Path).Name)"; Write-Output ''
    Write-Output ($o | select Algorithm, Hash)
    Write-Output ''
    Write-Output ('Get-FileHash -Algorithm SHA256 .\' + ([System.IO.FileInfo]::new($o.Path).Name) + ' |% { if ($_.Hash -eq "' + ($o.Hash) + '") { Write-Output "Test $([System.IO.FileInfo]::new($_.Path).Name) OK" } else { Write-Output "Test $([System.IO.FileInfo]::new($_.Path).Name) KO" }}')
