Strange product id in shopping cart

[tlahtine]

I'm developing some code for an observer, notified by NOTIFY_CHECKOUT_PROCESS_AFTER_ORDER_CREATE_ADD_PRODUCTS, i.e. after the order has been made.

I'm going trough the content of shopping chart $_SESSION[cart]->get_products()

When I display the product id's there is one strange id:
[id] = 183:b82db7468155b3b7ce02a50e8965db33

This is for a product, which actually has an id 183. But what the heck is the rest :b82db7468155b3b7ce02a50e8965db33 ???

That's a hash which represents the attributes selected by the customer when adding that product to their cart.
Products which don't have attributes don't have any hash added to them.

Thanks a lot!

Can I use the hash somehow i.e. decode what are the attributes selected?
