GoCryptFS
=========
A minimal encrypted overlay filesystem written in Go.
Built on top of the
native Go FUSE library [bazil.org/fuse](https://github.com/bazil/fuse)
and the [ClueFS](https://github.com/airnandez/cluefs) loopback file system.
Inspired by [EncFS](https://github.com/vgough/encfs).
Design
------
* Authenticated encryption of file contents using AES-GCM-128
* 96 bit nonce that starts from a random value and counts up
* uses openssl through [spacemonkeygo/openssl](https://github.com/spacemonkeygo/openssl)
for a 3x speedup compared to `crypto/cipher`
* AES-CBC filename encryption
Current Status
--------------
* Work in progress
* Key is set to static all-zero
* Not ready for anything but testing and debugging
Install
-------
go get github.com/rfjakob/gocryptfs
Testing
-------
Run `./main_benchmark.bash` to run the test suite and the streaming read/write
benchmark.
The output should look like this:
$ ./main_benchmark.bash
+ go build
+ go test -bench=.
PASS

BenchmarkStreamRead 100 11267741 ns/op 93.06 MB/s
