如何将此 C# Rijndael 加密转换为 PHP?

I don't understand encryption enough to work out what I'm doing wrong.

这是php版本:

$pass = 'hello';
$salt = 'application-salt';

echo Encrypt('hello', 'application-salt');

function Encrypt($pass, $salt)
{
    $derived = PBKDF1($pass, $salt, 100, 16);
    $key = bin2hex(substr($derived, 0, 8));
    $iv = bin2hex(substr($derived, 8, 8));
    return mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key, $pass, MCRYPT_MODE_CBC, $iv);
}

function PBKDF1($pass, $salt, $count, $dklen)
{
    $t = $pass.$salt;
    $t = sha1($t, true);
    for($i=2; $i <= $count; $i++)
    {
        $t = sha1($t, true);
    }
    $t = substr($t,0,$dklen-1);
    return $t;
}

还有 C# 版本:

Console.WriteLine(Encrypt("hello", "application-salt"));
// output: "Hk4he+qKGsO5BcL2HDtbkA=="

public static string Encrypt(string clearText, string Password)
{
    byte[] clearData = System.Text.Encoding.Unicode.GetBytes(clearText);
    PasswordDeriveBytes pdb = new PasswordDeriveBytes(Password,
        new byte[] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 });

    MemoryStream ms = new MemoryStream();
    Rijndael alg = Rijndael.Create();
    alg.Key = pdb.GetBytes(32);
    alg.IV = pdb.GetBytes(16);
    CryptoStream cs = new CryptoStream(ms, alg.CreateEncryptor(), CryptoStreamMode.Write);
    cs.Write(clearData, 0, clearData.Length);
    cs.Close();
    byte[] encryptedData = ms.ToArray();

    return Convert.ToBase64String(encryptedData);
}

我希望能够在一个新的基于 php 的应用程序中验证用户登录，该应用程序将与现有 C# 应用程序通信到同一个 MySQL 数据库.我打算加密密码并将生成的哈希值与存储在数据库中的哈希值进行比较以进行身份​​验证.

function Encrypt($pass, $salt)
{
     $derived = PBKDF1($pass, $salt, 100, 48);
     $key = bin2hex(substr($derived, 0, 32));
     $iv = bin2hex(substr($derived, 32, 16));
     return mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $key, $pass, MCRYPT_MODE_CBC, $iv);
}
