Bazil Transport Experiment

Built for a discussion on the bazil filesystem, which needs a transport layer.

This experiment uses docker/libchan and authenticates a TLS-encrypted libchan SPDY connection using TLS client and server ceritificates. It assumes both peers know each other's NaCl public keys (shared via local filesystem in this experiment).

The NaCL keys are used to do a handshake via HTTP that exchanges the peers' TLS-certificates' signatures, signed via NaCl (and encrypted, that would not be required, but was easier to do). The signatures are stored in memory and used to verify following TLS-connections on both ends.

The TLS certificates are generated on startup, the NaCl key pairs are generated when first needed and then persisted in the certs folder.

The experiment uses libchan's rexec rexample and allows executing a 'remote' shell command including stdin/stderr/stdout passing, which demonstrates libchan's stream / Go channel multiplexing.

Usage

go get github.com/meeee/bazil-transport-experiments
cd src/github.com/meeee/bazil-transport-experiments
go build server.go
./server

In a different shell for the client:

cd src/github.com/meeee/bazil-transport-experiments/client
go build client.go
cd .. # otherwise it doesn't find the NaCl certs
# execute `ls -l` on the server
client/client ls -l
