Hi,
Im about to make a "game" which can be used as a text editor.
The thing is, the docs are encrypted. I want to use my gba micro to save my passwords. I have a EZ Flash IV.
So Ive never programmed something in C, but its worth a try.
I tried to learn the language some time ago, but the thing with the pointers is pretty hard to learn.
I see the concept behind it, but the gba-tutorials dont go very deep into this topic.
I think Im going to use this code f?r the en- and decryption part:
http://www.literatecode.com/aes256
The text will be unformatted, some KB big. I want to create more than one container.
So maybe 4 containers (textfiles) which can be choosed to open and saved with a individual password.
The EZ Flash has the function, to not loose the informations when its shut down.
Well - this will be a secure problem for me, so I am looking for ideas how I can handle this.
There should be no encrypted data on the modul when I shut it down.
Savegames are the crypted textfiles.
The encryption should be fast, thats the main point.
I dont want a good looking design, when it slows down the encryptionengine.
short: How do I start? Does something like this exists already?
