How did TCG deck builders restore a deck from hash?

Question

TCG = Trading Card Game
A hash is normally a one way street.
How can deck builder build a deck from a hash?

One idea I have is that they save all decks in a database and the hash works only for integrity. But isn't it a mess of data to save all decks. I mean you can build a deck even if you don't have a account.

In the code below I have 2 decks from different games.

Answer 1

Hi! You assume that everybody knows what a deck in a game is. I’m not sure that’s the case, but maybe it’s just me…

But it’s seems like you need some kind of dictionary. The keys in a dictinary are all unique. Is this what you needs?

What is a hash in your question; is it something in a game or like a hash function in programming?

Do you mean that the ”hash” represent a type of card, and you should build a set of card depending on only that type of cards?

Answer 2

Per Bratthammar thank you for your reply.

I come to the conclusion, that in the first game I posted in my code, they are using the hash as an indentifer. So they save all decks in a database and search them with this hash.

The second game saved all information in the hash itself. So that each card has a specific value.

And in this case I mean with hash a string created with a algorithm.
