securefs is a filesystem in userspace (FUSE) with transparent encryption (when writing) and decryption (when reading).
securefs mounts a regular directory onto a mount point. The mount point appears as a regular filesystem, where one can read/write/create files, directories and symbolic links. The underlying directory will be automatically updated to contain the encrypted and authenticated contents.
securefs is free and open source software.
Key Features
- Authenticated encryption (hence secure against chosen ciphertext attacks).
- Probabilistic encryption (hence provides semantical security).
- Efficient cloud synchronization (not a single preallocated file as container).
- File contents:
- Uses GCM for encryption and integrity.
- File names:
- Uses AES-SIV for encryption.
- Cross-platform support – runs under Linux, BSD, macOS, and Windows.
