Compile gocryptfs from Source

Install Go 1.13 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

See also: README.md#compile

Test

In the gocryptfs source directory, run:

./test.bash

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

gocryptfs v1.4.3-9-g9f8d0d8 without_openssl; go-fuse v20170619-28-g19acbd2; 2018-02-03 go1.9.2

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.
