A simple steganographic algorithm, exposed in library routines, a command-line interface, as well as a web proxy demonstration implementation.
go get chrispennello.com/go/steg
The command-line interface:
go get chrispennello.com/go/steg/cmd/steg
The web proxy demo:
go get chrispennello.com/go/steg/cmd/stegserve
stegserve can also be run as an App Engine application.
% sysctl hw.model hw.machine hw.ncpu
hw.model: AMD Phenom(tm) II X4 955 Processor
hw.machine: amd64
hw.ncpu: 4
The following test was performed. Each benchmark run represents a test of muxing an appropriate number of message bytes into three million carrier bytes.
% go test -bench . -benchtime 60s
PASS
Benchmark1 100 683815634 ns/op
Benchmark2 50 1501107422 ns/op
Benchmark3 50 1738694850 ns/op
This yields the following throughput statistics.
1 byte per atom 4.387MB/s
2 bytes per atom 1.999MB/s
3 bytes per atom 1.725MB/s
