Alternatives to CryFS
An encrypted filesystem that protects files stored in cloud storage, including their metadata and folder structure. The listings below can replace it for an important use case. Each note says what changes if you switch.
The original
CryFS
An encrypted filesystem that protects files stored in cloud storage, including their metadata and folder structure.
Replacements
Listings that take over the same core job as CryFS.
Cryptomator
Encrypts a folder inside your existing cloud storage, so Dropbox or OneDrive holds files it cannot read.
Cryptomator adds Windows, Android and iOS apps and encrypts file names and contents, though its mobile apps are separate paid purchases.
gocryptfs
An encrypted overlay filesystem for Linux that encrypts each file individually, so cloud sync and backups only move what changed.
gocryptfs encrypts each file individually and had an independent 2017 audit, but directory structure and file sizes stay visible, unlike CryFS, and macOS support is beta.
securefs
Mounts an encrypted directory as a normal filesystem.
securefs encrypts and authenticates files individually for cloud sync folders and adds Windows support through WinFsp, but it is command-line only.
cppcryptfs
Mounts a gocryptfs-encrypted folder as a Windows drive letter, encrypting file contents and names transparently.
cppcryptfs brings gocryptfs-compatible encrypted folders to Windows, which CryFS lacks, but directory structure and file sizes remain visible and it needs the Dokany driver.
Also worth comparing
These listings name CryFS as their own alternative, so the relationship runs both ways.
AxCrypt
A file encryption app that protects files and folders with AES-256 before sharing or cloud storage.
CryFS is a free LGPL-3.0 encrypted filesystem that hides metadata in any cloud sync folder, but it runs only on macOS and Linux and suits sharing poorly.
fscrypt
A command-line tool, written in Go, for managing native Linux filesystem encryption on ext4 and F2FS.
CryFS encrypts a folder through its own filesystem and hides metadata and folder structure, working on macOS and Linux and suited to cloud sync folders.
StableBit CloudDrive
A Windows app that creates encrypted virtual hard drives whose data is stored with a cloud provider.
CryFS encrypts files and folder structure inside a normal cloud sync folder on macOS and Linux, rather than creating a virtual drive, and is open source.
Similar software
Related functionality, not a direct replacement.
SiriKali
Graphical manager for encrypted folders created by gocryptfs, securefs and similar tools.
zuluCrypt
A Linux GUI and command-line tool for creating, opening and managing encrypted volumes and files.
NordLocker
End-to-end encrypted cloud storage for backing up, syncing and sharing files across devices.
Icedrive
A cloud storage service with 10GB free, client-side encryption and a mountable virtual drive.
Tahoe-LAFS
A decentralized storage system that spreads encrypted files across multiple servers you control.
VeraCrypt
Disk encryption that creates encrypted containers, encrypts whole partitions, and can encrypt the drive Windows boots from.
