get md5-hash (Supports filesize > 2GB but is very slow!)

gistfile1.txt

function md5hash($path)
{
    $fullPath = Resolve-Path $path
    $md5 = new-object -TypeName System.Security.Cryptography.MD5CryptoServiceProvider
    $file = [System.IO.File]::Open($fullPath,[System.IO.Filemode]::Open, [System.IO.FileAccess]::Read)
    [System.BitConverter]::ToString($md5.ComputeHash($file))
    $file.Dispose()
}


md5hash($args[0])

should be noted that you could also swap the service provider in line 4 to one of the following. The interface is the same, so it should work right away:

• SHA1CryptoServiceProvider
• SHA256CryptoServiceProvider
• SHA384CryptoServiceProvider
• SHA512CryptoServiceProvider
