500 points to the guru that will help me finish that in time and provide me a routine that will take a string as input and will return me the 32 chars MD5 Digest generated by your routine (method or function)

Thanks a lot in advance !

If I understand what you are asking for this should do the trick...

using System.Security.Cryptography


public string EncryptString( string str ) {
   string rStr
   try {
     
      byte[] data = Encoding.Default.GetBytes(str);

      // This is one implementation of the abstract class MD5.
      MD5 md5 = new MD5CryptoServiceProvider();

      byte[] result = md5.ComputeHash(data);

      char[] chars = Encoding.Default.GetChars(result, 0, result.Length);
      rStr = new string(chars);

   } catch ( Exception ex ) {
      // do something with the exception!
   }
   return rStr;
}

hashLength = 32;
                    data = Encoding.Default.GetBytes(text);
                    MD5 md5 = new MD5CryptoServiceProvider();
                    enc = md5.TransformFinalBlock(data, 0, data.Length);
                    foreach(byte b in md5.Hash)
                        hash += Convert.ToString(b, 16).ToUpper().PadLeft(2, '0');
                    md5.Clear();

hashLength = 32;  is never used ? Normal ?

            public string GetMD5Digest(string input)
            {
                  int hashLength = 32;
                  string hash;
                  byte[] data = Encoding.Default.GetBytes(input);
                  MD5 md5 = new MD5CryptoServiceProvider();
                  byte[] enc = md5.TransformFinalBlock(data, 0, data.Length);
                  foreach(byte b in md5.Hash)
                        hash += Convert.ToString(b, 16).ToUpper().PadLeft(2, '0');
                  md5.Clear();
                  return hash;
            }
