Perfect 'Save/Load' code.

Perfect 'Save/Load' code.

I have just come across MrMaestro's Integer Save/load, it is very uncrackable, and with a few tweaks, could be very good. Now, I am yet to see a save/load code that does all of the following:
~
-Saves all items, and put them in the right positions
-Saves level
-saves EXP. (I have never seen this)
-saves skill points
-saves all hero attributes (Easy enough to do)
-saves 'what skills' you have chosen, instead of just giving you 27 skill points.
-saves gold
-saves lumber
-and is uncrackable (MrMaestro's is a good place to start)
So, if someone would somehow create an Uncrackable (un-stealable/guessable) save/load with all of the following, that would be pretty incredible!
But also, is this even possible to create?

nothing is 'uncrackable' -- on the same token it is very easy to make something nearly impossible to crack, ie encode 1 digit into 4x10^25 characters -- of course you can see how the second case is unacceptable for remembing or writing down

making something short with hard encryption is something u go through lots of school for

i guess it depends how long u want the code to be at most

I would assume, adding all of those into one save/load script would add up to about 20-30 digits.

If you want a save code to save all that things, the save code would be bigger than 20-30 digits maybe 40 or 50 or bigger.

And you dont need to save levels if you also save exp.
