Current Status
|

--------------
|
||||
* Feature-complete and working
|
||||
* Passes the fuse-xfstests "generic" tests with one exception, results: [XFSTESTS.md](XFSTESTS.md)
|
||||
* A lot of work has gone into this. The testing has found bugs in gocryptfs
|
||||
as well as in go-fuse.
|
||||
* The one exception is generic/035. This is a limitation in go-fuse,
|
||||
check out https://github.com/hanwen/go-fuse/issues/55 for details.
|
||||
* However, gocryptfs needs more real-world testing - please report any issues via github.
|
||||
* Only Linux operation has been tested. Help wanted for Mac OS X verification.
|
||||

Beta. You are advised to keep a backup of your data outside of gocryptfs, in
|
||||
addition to storing the *master key* in a safe place (the master key is printed
|
||||
when mounting).
|
||||
|
||||
That said, I am dogfooding on gocryptfs for some time now. In fact, all gocryptfs
|
||||
development happens inside a mounted gocryptfs filesystem, with no issues so far.
|
||||
|
||||
Only Linux is supported at the moment. Help wanted for a Mac OS X port.
|

|
||||
Testing
|
||||
-------
|
||||
|
||||
gocryptfs comes with is own test suite, run it using `./test.bash`.
|
||||
|
||||
In addition, i have ported `xfstests` to FUSE, the result is the
|
||||
[fuse-xfstests](https://github.com/rfjakob/fuse-xfstests) project. gocryptfs
|
||||
passes the "generic" tests with one exception, results: [XFSTESTS.md](XFSTESTS.md)
|
||||
|
||||
A lot of work has gone into this. The testing has found bugs in gocryptfs
|
||||
as well as in go-fuse.
|
||||
|
||||
The one exception is generic/035, see [go-fuse issue 55](https://github.com/hanwen/go-fuse/issues/55)
|
||||
for details. While this is a POSIX violation, I do not see any real-world impact.

---------
|
||||
|
||||
v0.4 (in progress)
|
||||
* Add `--plaintextnames` command line option
|
||||
* Can only be used in conjunction with `--init` and disables filename encryption
|
||||
* Add `-plaintextnames` command line option
|
||||
* Can only be used in conjunction with `-init` and disables filename encryption
|
||||
(added on user request)
|
||||
* Add `FeatureFlags` config file paramter
|
||||
* This is a config format change, hence the on-disk format is incremented
