dirLocker is a state-of-the-art cryptographic vault engineered for plausible deniability and absolute content secrecy. By fusing a high-performance Rust cryptographic core with a flexible Go application layer and a Flutter mobile client, dirLocker delivers military-grade security that integrates seamlessly into your native workflow.
| Feature | Description |
|---|---|
| 🛡️ Ironclad Security | Powered by Rust, utilizing XChaCha20-Poly1305 & AES-256-GCM for high-speed, authenticated encryption. |
| 👻 Plausible Deniability | Create Hidden Volumes inside your vault. Reveal a decoy password under coercion, keeping your true data mathematically invisible. |
| ⚡ Zero-Lag Mounting | Mount vaults directly as drives using FUSE (Linux/macOS) and Dokany/WinFSP (Windows). Edit files in-place with native performance. |
| 📱 Mobile Ready | Full-featured Android/iOS client built with Flutter. Manage your encrypted vaults on the go. |
| 🌑 Stealth Mode | Features OS-level file obfuscation and anti-forensic techniques to prevent analysis. |
| 👆 Biometric Unlock | Unlock your vault instantly using Windows Hello, TouchID, or Linux Secret Service. |
dirLocker bridges the gap between high-level usability and low-level security through a hybrid architecture:

Prerequisites: Go 1.24+ • Rust 1.70+ • Flutter 3.13+
🖥️ Desktop (Windows/Linux/macOS)
# Build the CLI and Desktop GUI
make build📱 Mobile (Android)
# Build the Mobile APK
cd clients/mobile
flutter pub get
flutter build apk --release1. Initialize a Vault:
./bin/dirlocker-cli init --path ./my-secret-vault --size 1GB2. Mount it:
./bin/dirlocker-cli mount --path ./my-secret-vault --mountpoint ./mnt3. Done! Any files copied to ./mnt are now encrypted on the fly.
