"Go" How To make PHP MD5 and C # MD5 consistent?

There is the code for C # generation MD5 as follows:

   ClassCreateMD5 {StaticvoidMain(String[] (args) {String Source = "question Guide"; using (MD5 Md5hash = MD5. Create ()) {string hash = Getmd5hash (Md5hash, source); Console.WriteLine (hash); }} static string getmd5hash (MD5 Md5hash, string input) {//here is the Unicode byte[] data = Md5hash.computehash ( Encoding.Unicode.GetBytes (input)); StringBuilder Sbuilder = new StringBuilder (); for (int i = 0; i < data. Length; i++) {sbuilder.append (Data[i]. ToString ( "X2")); } return sbuilder.tostring ();}}         

The MD5 generated by the above code is F5DA53705563C657581A6D0853286FDC now the problem is that C # generates MD5 inconsistent with the MD5 generated by PHP

Because of business constraints, you cannot change C # code, only from PHP.

MD5 one step before the operation

Original: C # compatible with PHP MD5

Due to work needs, C # needs to be used to do two development of a PHP program. A minor problem was found during login verification.

The result of the MD5 algorithm written in C # and PHP's MD5 () is sometimes different. The password verification of some accounts does not pass. Later on the internet to find a bit, in a foreign site found the answer.

Common MD5 algorithms for C #.

public static string MD5 (string password) {   byte[] textbytes = System.Text.Encoding.Default.GetBytes (password);   try {      System.Security.Cryptography.MD5CryptoServiceProvider crypthandler;      Crypthandler = new System.Security.Cryptography.MD5CryptoServiceProvider ();      Byte[] hash = Crypthandler.computehash (textbytes);      string ret = "";      foreach (Byte A in hash) {            ret + = a.tostring ("x");      }      return ret;   }   catch {      throw;   }

}

However, the result of this algorithm is different from that of MD5 (). After the adjustment is as follows, that is possible.

public static string MD5 (string password) {   byte[] textbytes = System.Text.Encoding.Default.GetBytes (password);   try {      System.Security.Cryptography.MD5CryptoServiceProvider crypthandler;      Crypthandler = new System.Security.Cryptography.MD5CryptoServiceProvider ();      Byte[] hash = Crypthandler.computehash (textbytes);      string ret = "";      foreach (Byte A in hash) {         if (a<16)            ret + = "0" + a.tostring ("x");         else            ret + = a.tostring ("x");      }      return ret;   }   catch {      throw;   }

}
