Browse Source 
* whisper skeleton

* basic message store

* rallying and message logic

* pass host info to network protocol handlers

* choose who starts rally based on node key

* module reshuffling

* mining messages

* prune messages by low PoW until below size target

* associated error type for ethkey generators and `OsRng` generator

* beginnings of RPC

* generic message handler for whisper

* reshuffle code order

* standard payload encoding and decoding

* basic crypto

* minor restructuring of net code

* implement shh_post

* merge?

* implement filters

* rand trait for hash types

* filter RPCs for whisper

* symmetric encryption of payload

* pub-sub

* filter tests

* use only secure random IDs

* attach arbitrary protocols to network

* basic integration of whisper into Parity

* eagerly prune low PoW entries

* broadcast messages with salted topics

* node info RPC

* fix import

* fix leading zeros calculation

* address minor grumbles
