I like alternative wallets like Armory and Electrum because they offer more features, some of which are fundamental for security and convenience. But I'm a bit worried about them not being "compatible", I mean you can't import an Armory wallet into Bitcoin-qt.
So what I would like to know is whether it is possible to recover my bitcoins (which if I didn't get it wrong, they are in the blockchain and could be spent with the private key) using the official wallet. For instance, the paper backup generated by Armory contains a "root key" and a "chain code". Is one of those the private key or what?
