in reply to hiding the information in txt files

...that is going to be transfered(sic) over the net... I would not want everyone to look at them...
  1. What are your options to 'transfer over the net'? scp/sftp/https will all keep people from seeing them regardless of the format you choose.
  2. If you can't use a secure transport, you'll need to encrypt the file. Crypt::* has lots of options
  3. What moritz suggests is perfect if you don't care whether the numbers are seen by people; all you care about is that they get to the destination unchanged

    Ok, so i am going to use a classic https and i trust that is not going to be seen during the transfer , but i would also like, once the file is transfered, that it cannot be seen by the user. Only that the app, user is going to receive from me will be able to read those numbers. So i guess encription would be a way to go ... i guess ???

      If the data exists - even momentarily - on a machine in the user's control or physical possession and the user cares enough, he will be able to view the data. Period.

      You cannot prevent this. If you want to follow in the footsteps of the movie industry, you can spend very large amounts of money (definitely in the hundreds of millions of US dollars, probably billions) trying, but you will fail, just as they have failed.
