AES。加密PowerShell中的字節數組

Question

我需要使用AES加密方法在PowerShell腳本中加密字節數組（[byte []]）。我發現，編碼字符串函數：

[Reflection.Assembly]::LoadWithPartialName("System.Security") 

function Encrypt-String($String, $Passphrase, $salt="My Voice is my P455W0RD!",  $init="Yet another key", [switch]$arrayOutput) 
{ 
    $r = new-Object System.Security.Cryptography.RijndaelManaged 
    $pass = [Text.Encoding]::UTF8.GetBytes($Passphrase) 
    $salt = [Text.Encoding]::UTF8.GetBytes($salt) 

    $r.Key = (new-Object Security.Cryptography.PasswordDeriveBytes $pass, $salt, "SHA1", 5).GetBytes(32) #256/8 
    $r.IV = (new-Object Security.Cryptography.SHA1Managed).ComputeHash([Text.Encoding]::UTF8.GetBytes($init))[0..15] 

    $c = $r.CreateEncryptor() 
    $ms = new-Object IO.MemoryStream 
    $cs = new-Object Security.Cryptography.CryptoStream $ms,$c,"Write" 
    $sw = new-Object IO.StreamWriter $cs 
    $sw.Write($String) 
    $sw.Close() 
    $cs.Close() 
    $ms.Close() 
    $r.Clear() 
    [byte[]]$result = $ms.ToArray() 
    if($arrayOutput) { 
    return $result 
    } else { 
     return [Convert]::ToBase64String($result) 
    } 
}

有助於改變功能，使得它編碼的字節數組，而不是一個字符串

我這樣做，我需要。新代碼：

[Reflection.Assembly]::LoadWithPartialName("System.Security") 

$String=$buff #ARRAY OF BYTES TO ENCODE 
$Passphrase="Pas" 
    $salt="My Voice is my P455W0RD!" 
    $init="Yet another key" 

    $r = new-Object System.Security.Cryptography.AesManaged 
    $pass = [Text.Encoding]::UTF8.GetBytes($Passphrase) 
    $salt = [Text.Encoding]::UTF8.GetBytes($salt) 

    $r.Key = (new-Object Security.Cryptography.PasswordDeriveBytes $pass, $salt, "SHA1", 5).GetBytes(32) #256/8 
    $r.IV = (new-Object Security.Cryptography.SHA1Managed).ComputeHash([Text.Encoding]::UTF8.GetBytes($init))[0..15] 
    $r.Padding="Zeros" 

    $c = $r.CreateEncryptor() 
    $ms = new-Object IO.MemoryStream 
    $cs = new-Object Security.Cryptography.CryptoStream $ms,$c,"Write" 
    $cs.Write($String, 0,$String.Length) 
    $cs.Close() 
    $ms.Close() 
    $r.Clear() 
    [byte[]]$Encrypted = $ms.ToArray()
