(Or, how to better organise a discreet relationship with the Director of the CIA.)
At this point, I welcome technical feedback on the design and comments from the sort of (often non-technical) folks who need this sort of thing about whether it actually meets their needs.
For details, see the main website.
The code here is broken down as follows:
bbssigcontains an implementation of the BBS group signature scheme. This is used in Pond to allow servers to reject messages from non-contacts without the server being able to identify those contacts.
bn256cgocontains a wrapping of Naehrig, Niederhagen and Schwabe's pairing library. This is a drop in replacement for the bn256 package from go.crypto and speeds up bbssig. See https://github.com/agl/dclxvi.
clientcontains the Pond GUI and CLI client and package for manipulating state files.
doccontains the https://pond.imperialviolet.org site in Jeykll format.
editstatecontains a debugging utility for manipulating state files.
pandacontains a library for performing shared-key exchanges. It's used by
client/to implement that functionality.
protoscontains the protocol buffer files for client to server communication.
servercontains the Pond server.
transportcontains code to implement the, low-level, client to server transport protocol.
