In package-manager terms it sits at the intersection of FUSE filesystem tooling, local encryption utilities, and privacy-oriented desktop workflows. ### Project history CryFS was published as an open-source cryptographic filesystem for the cloud, with its official site describing a design that encrypts content, filenames, directory structure, timestamps, and other metadata into fixed-size encrypted blocks. The official technical page cites a 2015 master's thesis and a 2017 DBSec publication for the security analysis behind the design. ### Adoption history The upstream README documents distribution through apt, pacman, Homebrew, MacPorts, Nix, and experimental Windows builds, and also mentions GUI integrations such as SiriKali and KDE Plasma Vault. That breadth explains why package managers carry CryFS even though it is a specialized filesystem tool: users need it installed close to the operating system, FUSE layer, and desktop integration points. ### How it is used A typical CryFS workflow creates a vault directory, stores an encrypted configuration file named cryfs.config there, and mounts decrypted contents through the cryfs command. Its cloud-storage focus is visible in the official examples naming Dropbox, iCloud, OneDrive, and similar services, while the docs warn about non-concurrent use and corruption risks if multiple devices or sync clients write at the same time. ### Why package nerds care CryFS matters to packagers because it pulls ordinary package management into filesystem integration: macOS users need macFUSE, Linux users need FUSE support, Windows builds use DokanY, and the project has historically cared about distro packages as first-class install routes. The package is therefore more than a binary drop; it is a small filesystem stack with platform-specific runtime expectations. ### Timeline - 2015: The official security-analysis page cites the CryFS master's thesis. - 2017: The official site cites a DBSec publication on the CryFS construction. - 2024: CryFS 1.0.0 was published on the official GitHub releases page. - 2025: The 1.0.x and 2.0.0-alpha release lines were active on GitHub. ### Related projects - The CryFS documentation contrasts its block-based metadata-hiding approach with file-based encrypted filesystems such as EncFS and gocryptfs, and the README points to SiriKali and KDE Plasma Vault as GUI front ends that can use CryFS. ### Sources - - - ## Security Notes broad file, network, media, or database tool signal. infrastructure mutation or orchestration signal. - **Geiger risk:** orange / medium - broad file, network, media, or database tool signal - infrastructure mutation or orchestration signal ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials. Automic Vault can use them as review targets for secret scanning, migration, and command approval. ## Configuration files - Unix: vaultdir/cryfs.config ## Other Package-Manager Records - Debian apt - cryfs - 0.11.4-3: normalized package name match | Debian stable package indexes: cryfs from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | encrypt your files and store them in the cloud | https://www.cryfs.org/ - Ubuntu apt - cryfs - 0.11.4-1build5: normalized package name match | Ubuntu 24.04 LTS package indexes: cryfs from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | encrypt your files and store them in the cloud | https://www.cryfs.org/ - dnf - cryfs - 0.11.3-19.fc45: normalized package name match | Fedora Rawhide package metadata: cryfs from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/07190dc5ae9f35ae73866675fed6d95fe6e8d9fe22c9d7cdf85862cb2ed24a4c-primary.xml.zst | Cryptographic filesystem for the cloud | https://www.cryfs.org/ - pacman - cryfs - 1.0.3-5: normalized package name match | Arch Linux sync databases: cryfs from https://geo.mirror.pkgbuild.com/extra/os/x86_64/extra.db.tar.gz | Cryptographic filesystem for the cloud | https://www.cryfs.org - zypper - cryfs - 1.0.3-1.8: normalized package name match | openSUSE Tumbleweed package metadata: cryfs from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | Cryptographic filesystem for the cloud | https://www.cryfs.org/ - MacPorts - cryfs: normalized package name match | MacPorts ports tree: fuse/cryfs/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Combined YAML source View the package source record on GitHub.
