Introduction to Dicloak
Dicloak stands out by its hybrid approach: it combines strong encryption with a dynamic masking mechanism. Unlike traditional utilities, it can protect files continuously and adapts to various scenarios, whether for individual workstations or critical enterprise servers. The official documentation, validated by the security team at the University of Cambridge, attests to its robustness against brute force attacks.
Technical prerequisites
Before starting the installation, verify that your environment meets the following requirements:
- Operating system: Linux (Debian/Ubuntu/CentOS), Windows 10/11, or macOS 10.15+
- Processor: Dual-core 2 GHz minimum

Downloading Dicloak
The starting point is to retrieve the package suited to your platform. Always choose the latest stable version to ensure the best reliability.
Choosing the appropriate version
On the official website, three editions coexist: Community Edition (free), Professional (with paid support), and Enterprise (multi-user). Select the one that fits your budget and expected support level.
Verifying file integrity
Once the download is complete, validate the SHA-256 checksum to avoid any corruption or compromise:
| Platform | File | SHA-256 |
|---|---|---|
| Linux | dicloak-linux.tar.gz | 3f8a2e5d4c1b9bf7e8a…fa12 |
| Windows | dicloak-windows.zip | 7a9c4e2d1b3f5a8c9d…bb34 |
| macOS | dicloak-macos.dmg | 5b1d2f3a4c6e7g8h9i…cc56 |
Step-by-step installation
This section details the installation on each system. The commands are illustrative and customizable according to your configuration.
On Linux (Debian/Ubuntu)
- Extract the archive:
tar xzf dicloak-linux.tar.gz - Access the directory:
cd dicloak - Run the installer:
sudo ./install.sh - Enable the service:
sudo systemctl enable dicloak && sudo systemctl start dicloak
On Windows
- Unzip the ZIP into
C:Program FilesDicloak - Run
setup.exeas administrator - Follow the graphical wizard to select the data directory and encryption type
- Restart the system if prompted
Initial configuration
After installation, the configuration determines the protection level and the directories to monitor.
Master key generation
Dicloak uses a master key for all encryption processes. Create it with:
dicloak --generate-key --output /etc/dicloak/key.pem
Store this file offline and restrict its access to authorized users only.
Editing the configuration file
The file /etc/dicloak/config.yaml includes several sections:
- paths: directories to protect
- algorithm: AES-256 or ChaCha20
- logging: logging level (info, warning, error)
- updates: automatic update checking
A minimal example:
paths: - /home/user/Documents/secret algorithm: AES-256 logging: info updates: true
Testing and validation
Before going into production, verify that encryption and masking work without errors.
dicloak --status: displays the service statusdicloak --test /home/user/Documents/secret: attempts encryption/decryption on a test file- Check the logs in
/var/log/dicloak.logto spot any alerts
A successful test displays « All systems operational ».
Maintenance and updates
To maintain optimal protection, update Dicloak regularly. Enable the automatic module or run manually:
dicloak --update
In case of a second installation on another machine, reuse your master key and synchronize the configuration file to unify the settings.
