在C＃中解密PHP加密字符串 [英] Decrypt PHP encrypted string in C#

问题描述

我有一个用PHP加密的字符串，我想在C＃中解密。我使用下面的教程进行加密，但解密时遇到问题。任何人都可以张贴如何做到这一点的例子？

解决方案

希望这有帮助：

  class Program 
 {
 static void Main（string [] args）
 {
 Console.WriteLine器（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 =解码器（输入）; 
 byte [] decryptedBytes = crypto.TransformFinalBlock（decodedInput，0，decodeInput.Length）; 
 return Encoding.ASCII.GetString（decryptptedBytes）; 
} 
 
静态字节[]解码器（字符串输入）
 {
 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）; 
} 
 
返回字节; 
} 
} 
  

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?

解决方案

Hope this helps:

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;
    }
}
