Compressing as ZIP is not encrypting.
It's hard to really see the point here, and especially, why not use my MD5 plugin for example to encrypt the JSON string if that's what you want?
Then you can send stuff with AJAX to a website of your own (if you want "cloud saving") or yes use clay.io or some service like that.
I'm sorry, but I really don't get the point here.
Your case example makes little sense to me, I'm not sure exactly what you're wanting to do in points 2 and 5.
And as mentioned earlier, if you want to do "cloud saving", all the tools are already available there.
Also you mix cheating and cache clearing, it's really confusing.
Oh, does your plugin about MD5 exists? I will look up, it makes me wonder it can decrypt JSON for other computers, is true?
Yes i meant encrypting JSON, i never told about encrypting ZIP, it's used to store data for gamers, because the gamers know about what is ZIP, but im sure they don't even know what means is json.
ZIP is an excuse to save their personal data for the games on their hard drive.
2 and 5 are more like you download JSON to save data, it may load JSON data for other computers that they want to play. The problem is i don't see how to upload JSON.
