問題描述

我有一個用 PHP 加密的字符串，我想用 C# 解密.我使用下面的教程進行加密，但在解密時遇到問題.任何人都可以發布有關如何執行此操作的示例嗎?

I have a string encrypted in PHP that I would like to decrypt in C#. I used the tutorial below to do the encryption, but am having problems decrypting. Can anyone post an example on how to do this?

推薦答案

希望對您有所幫助:

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine(Decrypt("47794945c0230c3d"));
    }

    static string Decrypt(string input)
    {
        TripleDES tripleDes = TripleDES.Create();
        tripleDes.IV = Encoding.ASCII.GetBytes("password");
        tripleDes.Key = Encoding.ASCII.GetBytes("passwordDR0wSS@P6660juht");
        tripleDes.Mode = CipherMode.CBC;
        tripleDes.Padding = PaddingMode.Zeros;

        ICryptoTransform crypto = tripleDes.CreateDecryptor();
        byte[] decodedInput = Decoder(input);
        byte[] decryptedBytes = crypto.TransformFinalBlock(decodedInput, 0, decodedInput.Length);
        return Encoding.ASCII.GetString(decryptedBytes);
    }

    static byte[] Decoder(string input)
    {
        byte[] bytes = new byte[input.Length/2];
        int targetPosition = 0;

        for( int sourcePosition=0; sourcePosition<input.Length; sourcePosition+=2 )
        {
            string hexCode = input.Substring(sourcePosition, 2);
            bytes[targetPosition++] = Byte.Parse(hexCode, NumberStyles.AllowHexSpecifier);
        }

        return bytes;
    }
}
