Question about saving data

[Rugarus]

So I recently learned about being able to save data between Warcraft games and have them load/save and transfer to other games. But is this easily modified? Like let's say I saved a few integers which acted as game wins.

Is it easy or even possible to alter that data?

Depends obviously how you save data. You can write into a file, and the thing what you write into the file will also literally be written there.
So if you write there two numbers, "100" and "200", one might open this file, change numbers and test what it changes for him in game.

Usually if protection of such data is needed, them some encryption is used, and only the encrpyted form is then saved to file, which makes it harder everyone. Of course, before you can use the encrypted data, you have do decrypt it again, so the decryption algorithm has to be inside your map, too. An experienced user might take abuse of it, too.
