Hi Experts,

To protect my software, i'm trying to generate a unique computer id. I'm trying to combine Hardisk ID, Windows Key, MAC Address etc. My question is, after i retrieved all the above information, how should i compress all the information into 25 character computer id?

Thanks in advance

As short way to get Machine ID without installing package, do the following

1- Add the folder OnGuard\source to your project search path.
2- Add OnGuard unit to uses clause.
3- Create the following function to get machine id


uses OnGuard;

function GetMachineID: String;
begin
Result := IntToStr(ABS(CreateMachineID([midUser,
      midSystem, {midNetwork,} midDrives])));
end;

If you're going to use your method, you can collect information and compress them by this function


uses IdHashMessageDigest;

function CompressID(str:string):string;
var
  md5 : TIdHashMessageDigest5;
begin
  md5 := TIdHashMessageDigest5.Create;
  try
    Result:=copy(md5.HashStringAsHex(str), 1 , 25);
  finally
    md5.Free;
  end;
end;
