We need to use scrypt to do the wallet encryption to reduce the possibility for brute force attack. And we need to chose different difficult levels for different devices, mainly for mobile device and computers.

@peterlimg could you share an example or library? AES+ccb+pkcs5 is used on all web-apps to encrypt mnemonics. if it is not good, we need update all of them.
