How is wallet at official client encrypted? What encryption it use?
What encryption does Bitcoin-qt use and what encryption is used at Multibit? And how strong that encryption is compared to other methods?

Both bitcoind and bitcoinj use AES-256 encryption for the private keys in their wallets (this does not mean that the wallet formats are compatible though).
Bitcoin-Qt is just a GUI on top of bitcoind and Multibit is using bitcoinj internally, so the same should apply to them.

If by strength you mean key length it's 256 bit in both cases. – jnnk – 2013-11-30T21:34:04.470
ok, please add it to the post and add information how long does it take to crack it by supercomputers and how can quantum cryptography break that stuff. – Comodore – 2013-12-01T22:35:44.520
