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

问题描述

我在PHP中，我想在C＃解密加密的字符串。我用下面的教程做了加密，但我有解密的问题。任何人都可以张贴在如何做到这一点的例子吗？

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?

推荐答案

希望这有助于：

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;
    }
}
