Online store CMS for selling electronic goods?

Question

Electronic commerce

Hello, I need a CMS to sell digital goods, or rather links to pictures \ music \ books.
Attention! Buy 1 product "the key to the game", and users are given keys in turn, embedded in this product!
The following functionality is required: there is a list of keys for the game "Game of Life" 200 pieces. We buy a Game of Life key, after paying for the order, transferring it to the "paid" status, one of the activation keys will be provided to the user, and after the sale this key can no longer be used.
PS. You really don't want to produce 200 products with the same description.
ZYY. I found something suitable for the requirements, but I still want to know your opinion
