The name MD5Test does not exist in the current context

Question

Hi,

Trying to add server side $$anonymous$$-scores to my game, but struggling with t$$anonymous$$s error. I'm using the script located here: link text Thanks

Error is: The name MD5Test does not exist in the current context. It originates from line 6 of the code posted below.

 // Post Score
     IEnumerator PostScores()
     {
          //T$$anonymous$$s connects to a server side php script that will add the name and score to a MySQL DB.
         // Supply it with a string representing the players name and the players score.
         string hash = MD5Test.Md5Sum(userName + score + secretKey);
  
         string post_url = addScoreURL + "name=" + WWW.EscapeURL(name) + "&score=" + score + "&hash=" + hash;
  
         // Post the URL to the site and create a download object to get the result.
         WWW hs_post = new WWW(post_url);
         yield return hs_post; // Wait until the download is done
  
         if (hs_post.error != null)
         {
             print("There was an error posting the $$anonymous$$gh score: " + hs_post.error);
         }
     }

Looks like the script is missing an MD5 hash function. There's one here: http://wiki.unity3d.com/index.php?title=MD5

Don't know how cross platform it is if that's an issue.

Yeah, re read the page and found the link to that method.

Had to change: string hash = MD5Test.Md5Sum(userName + score + key) -> string hash = Md5Sum(userName + score + key);

You think it will work on Windows/Mac/Linux?

In the article you have a link to t$$anonymous$$s page: http://wiki.unity3d.com/index.php/MD5

Here you have the function:

 public  string Md5Sum(string strToEncrypt)
 {
     System.Text.UTF8Encoding ue = new System.Text.UTF8Encoding();
     byte[] bytes = ue.GetBytes(strToEncrypt);
  
     // encrypt bytes
     System.Security.Cryptography.MD5CryptoServiceProvider md5 = new System.Security.Cryptography.MD5CryptoServiceProvider();
     byte[] hashBytes = md5.ComputeHash(bytes);
  
     // Convert the encrypted bytes back to a string (base 16)
     string hashString = "";
  
     for (int i = 0; i < hashBytes.Length; i++)
     {
         hashString += System.Convert.ToString(hashBytes[i], 16).PadLeft(2, '0');
     }
  
     return hashString.PadLeft(32, '0');
 }

And you can put:

 string hash = Md5Sum(name + score + secretKey);
