Overview

Operation of the module is characterized by the following
qualities:

Speed*: Page load times are minimized by relying primarily on local data
storage and evaluating remote sync result only once they are available.
Security*: Data exposure is mitigated by encrypting data in local storage and
comparing remote repositories using cryptographic hash digests; data is
transferred in incremental operations to expose only what is strictly
necessary, and network connections are encrypted.
Minimal data transfer*: Cryptographic hash functions allow synchronization of
large amounts of data using a very small network footprint.
Multi-device access*: By periodically synchronizing with a centralized
server, peripheral client devices are also indirectly synchronized with one
another.
Data backup*: With data saved on multiple devices, any copy can be used to
restore another in the event of unforeseeable damage, loss or theft.
