We never ever store, or transmit over the network the user's master password nor any of its derivatives, therefore we don't nee to encrypt it. The user's master password is not encrypted, it is used to create the key to encrypt and decrypt user's data, and the encryption key created from the master password, as a derivative of the master password, is never stored or transmitted. This way, we can assure our users that even us cannot ever access their data.
