  • If someone cleans their cookies will it delete saved data? And how easy are they to hack?

  • No. Very easy.

    The NW local storage is separate from your browser's local storage. It's a sqlite database file. You can easily edit any of the values with something like: http://sqlitebrowser.org/

  • If someone cleans their cookies will it delete saved data? And how easy are they to hack?

    the last time I tried, if you clean all of the cache of your browser, the savegame will be deleted...

    about the hack, I belive you can encrypt the value....

  • I'm really hoping we get support for google saved games at some point; it would be crazy awesome to have a reliable, device-agnostic, cloud based solution with tons of hack-proof storage.

  • TiAm - agreed - that would be awesome! Thanks for the info everyone. Ribis - how would you go about encrypting the values?

  • No save system is hack-proof, because if the game can read the save, then so can someone else (in theory).

    NW.js storage is entirely separate from the browser. Clearing cookies/offline data/uninstalling any other browser on the system has no effect on NW.js' own storage.

  • btw: It seems WebStorage is reset everytime you update your app on Windows (Phone) Store.

    So its not possible to use it for savegame data. I have to try the Win8 Plugin Roming data and if Save/Load works on Win8.

  • Ashley - thanks for the info. Bl4ckSh33p - after you try it, please share if that works.

    Can you give a procedure sample of what your doing to causes the data clearance with Windows Phone store. I get a data clear wipe every time I upload a package through the developers tools. However if this is through store downloading, this is concerning.

  • TiAm - agreed - that would be awesome! Thanks for the info everyone. Ribis - how would you go about encrypting the values?

    There are two plugin for that... you select a key, and from this, you can encrypt the value when you will save a string...when construct2 will try to open the new string, the plugin convert the string in a correct value (with a correct key),

    this is an example, I try to find the plugin, when I get home I will link the plugin

    anyway, you can try to save the data in different way, I mean, if you need to store some coins, like 50, you can save like this:

    "23y9812yu3982u" this is to get confused, just random string "50" real value "u23u2undu" a new random string"25" check if they hack the coin "u3342uy2382938" random string

    without encrypt, you can make your own secure script... can be difficult, but can get harder to hack a single value...

    50 is the real coin, construct count just the 50, if they hack it, a function check if a coin/2 is = to 25 o close to it... so, they need to hack 2 value, but the original string will be:

    23y9812yu3982u50u23u2undu25u3342uy2382938

    construct2 will count the "u" tokenat, you now where the 50 and 25 are, for example

    and if you store like 5 variable, you will get a long string... and you can mix it... but there is a plugin to encrypt, so, this is just for fun

  • Ribis - Thank you. I look forward to checking the plugin out!

  • Thank you. I look forward to checking the plugin out!

    this plugin made by rexrainbow works perfect:

    https://www.scirra.com/forum/viewtopic.php?f=183&t=110919&p=810981&hilit=XOR#p810981

    Here the plugin, I made a simple example: https://www.umbriadesign.it/decrypt.capx

    I never use this plugin(I will use it), but I think, the best method will be like:

    the user register a new account, in the php file, one function insert a key for that user, so, every user has different key, just look at the example..

    anyway, this is very good to prevent easy hack from the SESSION value or webstorage
