EncFS MP vs. Alternatives: Which Encrypted Filesystem Should You Use?Encrypted filesystems help protect sensitive data at rest by making files unreadable without the correct key. EncFS MP (EncFS — Multi-Platform variant) is a modern take on EncFS that aims to improve compatibility and maintenance across Windows, macOS, and Linux. This article compares EncFS MP to several alternative encrypted-filesystem solutions, evaluates typical use cases, and gives guidance on which option is best depending on your needs.
What is EncFS MP?
EncFS MP is a multi-platform continuation and refinement of the original EncFS concept: a user-space encrypted filesystem implemented with FUSE (Filesystem in Userspace). Instead of encrypting entire block devices or partitions, EncFS MP encrypts files and directory structures individually and stores the ciphertext in a separate directory. When mounted with the correct password (or key), the filesystem exposes a decrypted view of files on-the-fly.
Key characteristics:
- Per-file encryption (not full-disk or block-level).
- Works in user space via FUSE on systems that support it.
- Typically used for encrypting directories or portable media (USB drives, cloud-synced folders).
- Focus on cross-platform compatibility and active maintenance compared to legacy EncFS.
Security model and trade-offs
Per-file encrypted filesystems like EncFS MP encrypt file contents and usually provide options for encrypting file and directory metadata (names, sizes, timestamps). That differs from full-disk or container approaches that encrypt everything uniformly at the block level.
Pros:
- Individual files can be synced or updated without rewriting a large container file.
- Easier to use with cloud-sync services (Dropbox, Google Drive, OneDrive) because only changed encrypted files are uploaded.
- Lower memory/disk overhead for small changes.
Cons:
- Potential metadata leakage if filenames, directory structure, or file sizes aren’t fully hidden.
- More complex to guarantee semantic security across file operations (renames, partial writes).
- Typically depends on FUSE and userland tooling, which can be a compatibility or performance limitation.

Security details and audits
- EncFS (original) had known design weaknesses and some security analyses that raised concerns about metadata leakage and certain cryptographic choices. EncFS MP aims to address many practical issues and modernize the codebase, but its security posture depends on chosen options (e.g., filename encryption on/off), correct configuration, and active maintenance.
- gocryptfs and CryFS were designed later specifically to address weaknesses found in EncFS:
- gocryptfs focuses on simplicity, strong filename encryption, and performance.
- CryFS was designed to provide better metadata protection and is intended for cloud use, though it can be slower and has different trade-offs.
- VeraCrypt and LUKS/dm-crypt provide full-block encryption; they avoid per-file metadata leakage by encrypting entire containers or devices. They are generally considered robust and widely audited.
- Cryptomator and rclone crypt are tailored for cloud-synced encryption, prioritizing filename and directory structure protection while keeping compatibility with cloud providers.
Typical use cases and which tool fits best
- Portable encryption for cloud-synced directories (Dropbox/Drive): gocryptfs, CryFS, Cryptomator, or EncFS MP — choose one that supports filename encryption and is well-maintained on your platforms. gocryptfs often offers the best performance; CryFS offers stronger metadata hiding but can be slower.
- Encrypting USB sticks for sharing across OSes (Windows/macOS/Linux): EncFS MP or gocryptfs for per-file portability; VeraCrypt if you prefer a single encrypted container and want wide GUI support on all OSes.
- Full-disk or system encryption: LUKS/dm-crypt on Linux, BitLocker on Windows, FileVault on macOS — these protect everything including OS files and swap.
- Strong, audited security for sensitive archives: VeraCrypt containers or LUKS volumes are preferable because they minimize metadata leakage and have mature threat models.
- Programming/automation & cloud backends: rclone crypt integrates directly with many cloud providers; gocryptfs/gocryptfs reverse mount can be automated in scripts.
Practical considerations (performance, backups, recovery)
- Backup complexity: Per-file encrypted systems make incremental backups straightforward. Container-based systems (VeraCrypt) require backing up a large container file, which may be inefficient for small changes.
- Corruption and recovery: If an encrypted per-file store gets partially corrupted, only affected files are lost. If a VeraCrypt container or LUKS header is corrupted and not backed up, the entire container may become unreadable. Always backup headers/keys where applicable (LUKS header, VeraCrypt volume header).
- Password/key management: Use strong passphrases and consider using keyfiles or hardware tokens if supported. Keep secure offline backups of recovery keys/headers.
- Compatibility and tooling: EncFS MP relies on FUSE and platform ports; that may be easier for tech-savvy users but trickier for non-technical users expecting native GUI support.
Recommendations
- If you need cross-platform, cloud-friendly per-file encryption with good performance: consider gocryptfs or EncFS MP (prefer gocryptfs if you prioritize audit-backed cryptography and performance).
- If metadata privacy (filenames, directory structure) is critical: consider CryFS or Cryptomator.
- If you need full-volume/system encryption or the highest confidence against metadata leakage: use LUKS/dm-crypt (Linux) or VeraCrypt containers (cross-platform).
- For cloud-native workflows integrated with many providers: rclone crypt or Cryptomator are practical.
Example decision matrix (short)
- Casual user syncing documents to cloud, wants easy restore: gocryptfs or Cryptomator.
- Power user with mixed OSes wanting portable encrypted folders: EncFS MP or gocryptfs.
- Need maximum confidentiality, including filenames and sizes: CryFS or LUKS (depending on portability).
- Full disk/system encryption: LUKS, BitLocker, or FileVault.
Final notes
Choose based on threat model, convenience, and platform. For most cloud-sync and portable-folder scenarios, modern per-file solutions (gocryptfs, EncFS MP, Cryptomator) offer the best balance. For maximal confidentiality and robustness, prefer full-volume encryption (LUKS or VeraCrypt) and make sure to back up headers and keys.
