如何解码MD5字符串 [英] How to decode MD5 string

问题描述

我正在使用此代码制作加密密码。我想将生成的字符串解码为原始字符。

I am using this code to make a encrypted password.I want to decode the generated string to its original.

public string CreateHash(string password, string salt)
   {
       // Get a byte array containing the combined password + salt.
       string authDetails = password + salt;
       byte[] authBytes = System.Text.Encoding.ASCII.GetBytes(authDetails);
       // Use MD5 to compute the hash of the byte array, and return the hash as
       // a Base64-encoded string.
       var md5 = new System.Security.Cryptography.MD5CryptoServiceProvider();
       byte[] hashedBytes = md5.ComputeHash(authBytes);
       string hash = Convert.ToBase64String(hashedBytes);
       return hash;
   }

推荐答案

MD5哈希不能被解密，这就是MD5的全部要点。

最多，您可以尝试在彩虹表中查找它们。



以下是一些支持此功能的网站：

MD5 hashes can not be "decrypted", thats the whole point of MD5.
At max, you can try to look them up in a rainbow table.

Here are some sites that support this:

MD5算法不可能被称为单向散列函数。请参阅： http://en.wikipedia.org/wiki/MD5 [ ^ ]

It's not possible MD5 algorithm is known as one-way hashing function. Please, see this: http://en.wikipedia.org/wiki/MD5[^]

MD5是一种单向算法。它已加密但无法解密。



我仍​​然有一个代码来解密字符串。

Hi,

MD5 is a one way algorithm. it is encrypted but can't be decrypted.

still i have a code to decrypt the string.

public string DecryptPassowrd(object obj)
    {
        string password = obj.ToString();

        System.Text.UTF8Encoding encoder = new System.Text.UTF8Encoding();

        System.Text.Decoder utf8Decode = encoder.GetDecoder();

        byte[] todecode_byte = Convert.FromBase64String(password.Replace("","+"));

        int charCount = utf8Decode.GetCharCount(todecode_byte, 0, todecode_byte.Length);

        char[] decoded_char = new char[charCount];

        utf8Decode.GetChars(todecode_byte, 0, todecode_byte.Length, decoded_char, 0);

        string result = new String(decoded_char);

        return result;

    }

让我知道它是否适合你？



标记它是否适合您。



谢谢。

Let me know if it works for you or not?

Mark if it works for you.

thanks.
