Keybase Filesystem (KBFS) Keyword Search

This repository contains a preliminary implementation of the client-side code for the Keybase Filesystem (KBFS) Keyword Search. See the wiki for a brief introduction and overview.

All code is written in the Go Language, and relies on KBFS.

Architecture

This client allows keyword searching for files stored in KBFS. It relies on KBFS for syncing the master secrets and communicates remotely with the search server to update the indexes stored on the server and perform keyword searches.

The code is organized as follows:

• client: The client-side code for the search scheme.
• genprotocol: Contains the AVDL files defining client-server RPC communication. If you need to make protocol changes, edit the files in this directory.
• libsearch: Our implementation of the secure index and other helper functions.
• protocol: Contains auto-generated code derived from the protocol definitions in genprotocol/. Should not be edited by hand.
• prototype: An early-stage prototype the implements the search scheme locally.
• vendor: Vendored versions of the open-source libraries used by KBFS search.

Running the Client

Once the search server is up and running at SERVER_ADDRESS:SERVER_PORT, to start the client and enable searches in specific KBFS_DIRECTORIES_TO_SEARCH (separated by semicolons):

cd client/client
go run main.go --client_dirs=KBFS_DIRECTORIES_TO_SEARCH --ip_addr=SERVER_ADDRESS --port=SERVER_PORT

Use go run main.go --help to see other configurable parameters.

Licensing

Most code is released under the New BSD (3 Clause) License. If subdirectories include a different license, that license applies instead. (Specifically, most subdirectories in vendor are released under their own licenses.)
