问C#如何和php的des加密解密保持一致

using System;
using System.IO;
using System.Security.Cryptography;
using System.Text;

class Program
{
    static void Main()
    {
        string plainText = "Hello, World!";
        string key = "12345678"; // DES 密钥必须是 8 个字节
        string encryptedText = EncryptDES(plainText, key);
        Console.WriteLine("Encrypted Text: " + encryptedText);
    }

    static string EncryptDES(string plainText, string key)
    {
        byte[] keyBytes = Encoding.UTF8.GetBytes(key);
        byte[] plainBytes = Encoding.UTF8.GetBytes(plainText);

        using (DESCryptoServiceProvider desProvider = new DESCryptoServiceProvider())
        {
            desProvider.Key = keyBytes;
            desProvider.Mode = CipherMode.ECB; // 使用相同的加密模式
            desProvider.Padding = PaddingMode.PKCS7; // 使用相同的填充方式

            ICryptoTransform encryptor = desProvider.CreateEncryptor();
            byte[] encryptedBytes = encryptor.TransformFinalBlock(plainBytes, 0, plainBytes.Length);

            return Convert.ToBase64String(encryptedBytes);
        }
    }
}

<?php
$plainText = "Hello, World!";
$key = "12345678"; // DES 密钥必须是 8 个字节
$encryptedText = encryptDES($plainText, $key);
echo "Encrypted Text: " . $encryptedText;

function encryptDES($plainText, $key)
{
    $cipher = "DES-ECB"; // 使用相同的加密模式和算法
    $encryptedText = openssl_encrypt($plainText, $cipher, $key, OPENSSL_RAW_DATA | OPENSSL_ZERO_PADDING);
    $encryptedText = pkcs5_unpad($encryptedText);
    return base64_encode($encryptedText);
}

function pkcs5_unpad($text)
{
    $pad = ord($text[strlen($text) - 1]);
    if ($pad > strlen($text)) {
        return false;
    }
    if (strspn($text, chr($pad), strlen($text) - $pad) != $pad) {
        return false;
    }
    return substr($text, 0, -1 * $pad);
}
?>
