プロジェクトの歴史

The public GitHub repository was created in September 2015. The README says gocryptfs is built on go-fuse, was inspired by EncFS, and strives to fix EncFS security issues while providing good performance.

The project reached version 1.0 on July 17, 2016 after stress and correctness testing with fsstress, extractloop, and xfstests. The README also records a March 3, 2017 security audit, signed releases from v0.4 onward, Linux as the native platform, beta-quality macOS support, and a stable CLI ABI for scripts and applications.

採用の歴史

gocryptfs spread through the channels expected for a filesystem utility: upstream release binaries, Linux distribution packages, MacPorts, Homebrew, and package-manager metadata for Alpine, Debian, Fedora, Nix, Arch, Ubuntu, and openSUSE in the batch input.

Its adoption was helped by a clear operational niche: users wanted per-directory encryption that worked with sync tools and ordinary filesystems without placing trust in a full-disk-encryption layer or a cloud provider.

使われ方

The core workflow is to run `gocryptfs -init CIPHERDIR` and then mount `CIPHERDIR` at a plaintext mount point. The manpage also documents password changes, filesystem checks, info display, reverse mode, deterministic names, speed tests, and other operational flags.

gocryptfs stores encrypted data in CIPHERDIR and presents a plaintext view at MOUNTPOINT. Its `gocryptfs.conf` file is part of the encrypted directory metadata, while the password or master key remains the user's responsibility.

パッケージ好きにとっての重要性

Package nerds care about gocryptfs because filesystem tools are hard to package well: they touch FUSE, kernel interfaces, release signatures, platform caveats, and data safety. gocryptfs documents those edges unusually directly, including signed releases, security design, stable CLI ABI, benchmark expectations, and config-file recovery advice.

It is also a strong example of Go in systems-tool packaging: a single CLI with static-binary potential, distribution packages, and tight interaction with low-level OS facilities.
