Cryptography not available on target framework

Hi there,

currently trying out windows phone 8 development with Unity. Got a game which is storing the pref keys with an asset from the unity store. But when trying to export the game, ill get this error. Does anyone have a workaround for this? It is using the md5 hash:

Code (csharp):

1. public static string Md5Sum (string strToEncrypt)
2.     {
3.         System.Text.UTF8Encoding ue = new System.Text.UTF8Encoding ();
4.         byte[] bytes = ue.GetBytes (strToEncrypt);
5.  
6.         // encrypt bytes
7.         System.Security.Cryptography.MD5CryptoServiceProvider md5 = new System.Security.Cryptography.MD5CryptoServiceProvider ();
8.         byte[] hashBytes = md5.ComputeHash (bytes);
9.  
10.         // Convert the encrypted bytes back to a string (base 16)
11.         string hashString = "";
12.  
13.         for (int i = 0; i < hashBytes.Length; i++) {
14.             hashString += System.Convert.ToString (hashBytes [i], 16).PadLeft (2, '0');
15.         }
16.  
17.         return hashString.PadLeft (32, '0');
18.     }

 

Noone with any solution here? *bump*

 

Yeah, I know what it means, but I am not into that hash thing like maybe some other users are and already worked around saving playerprefs entcrypted with another format.
