|
* Group Messages....

|
|
* Forums / Channels / Blogs...
|
|
*
|
|
*
|
|
* Plan.
|
|
*
|
|
* (1) First create basic structures .... algorithms.
|
|
*
|
|
* (2) integrate with Cache Source/Store for data transmission.
|
|
* (3) integrate with Serialiser for messages
|
|
* (4) bring over the final key parts from existing p3channel.
|
|

*****************************************************************
|
|
*
|
|
* Group Description:
|
|
*
|
|
* Master Public/Private Key: (Admin Key) used to control
|
|
* Group Name/Description/Icon.
|
|
* Filter Lists.
|
|
* Publish Keys.
|
|
*
|
|
* Publish Keys. (multiple possible)
|
|
* Filters: blacklist or whitelist.
|
|
* TimeStore Length ??? (could make it a minimum of this and system one)
|
|
*
|
|
* Everyone gets:
|
|
* Master Public Key.
|
|
* Publish Public Keys.
|
|
* blacklist, or whitelist filter. (Only useful for Non-Anonymous groups)
|
|
* Name, Desc,
|
|
* etc.
|
|
*
|
|
* Admins get Master Private Key.
|
|
* Publishers get Publish Private Key.
|
|
* - Channels only some get publish key.
|
|
* - Forums everyone gets publish private key.
|
|
*
|
|
* Create a Signing structure for Messages in general.
