System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile() is obsoleted, use MD5 class instead.

MD5Hash.cs

string MD5Hash(string str)
{
	// return System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(pwd);
      
	var md5 = MD5.Create();
	var hashedBytes = md5.ComputeHash(Encoding.UTF8.GetBytes(str));
	var hashedStr = String.Join("", hashedBytes.Select(x => x.ToString("x2")));			
	return hashedStr;
}
