Compile gocryptfs from Source
=============================

Install Go 1.11 or higher:

* Debian/Ubuntu: `apt install golang`
* Fedora: `dnf install golang`

Then, download the source code and compile:

	$ git clone https://github.com/rfjakob/gocryptfs.git
	$ cd gocryptfs
	$ ./build-without-openssl.bash

This will compile a static binary that uses the Go stdlib crypto backend.

If you want to use the OpenSSL crypto backend (faster on
old CPUs lacking AES-NI), you have to install a few dependencies:

* Debian/Ubuntu: `apt install libssl-dev gcc pkg-config`
* Fedora: `dnf install openssl-devel gcc pkg-config`

Then, run:

	$ ./build.bash

Test
----

In the gocryptfs source directory, run:

	./test.bash

The tests run about 1 minute and should produce the following output:

```

You can run `./test.bash -v` to see the execution of individual tests. Note that
the tests also check error cases that produce error messages, and this is not
a test failure.
