🔐 Dynamic Secure Portable Volume (DSPV)

A portable, cross-platform encrypted container that creates a secure workspace on any USB drive or local folder without leaving traces on the host machine.

✨ Overview

DSPV transforms any standard folder into an encrypted vault. By placing the executable in a directory or USB drive, all files placed inside the designated secure folder are encrypted on disk.

Access is provided transparently via a local WebDAV server. You interact with your files through your OS's native file explorer, and DSPV handles the encryption and decryption on the fly in memory.

🛡️ Core Features

• True Portability: Single standalone executable. No drivers or administrative privileges required on the host machine.
• On-the-Fly Cryptography: Uses AES-256-XTS for robust disk encryption, identical to standards used by VeraCrypt and BitLocker.
• Strong Key Derivation: Master keys are derived using Argon2id with a random 32-byte salt to thwart brute-force attacks.
• Secure Memory Management: Cryptographic keys and plain-text buffers are managed with strict Zeroize traits, ensuring sensitive data is securely wiped from RAM immediately after use.
• Chunk-Based I/O: Files are not fully loaded into RAM. Read/Write operations are streamed and encrypted in chunks, allowing for the manipulation of massive files with minimal memory footprint.

🚀 Usage Workflow

1. Initialization

1. Copy the dspv executable to the root of your USB drive or desired folder.
2. Launch the executable.
3. You will be prompted to enter a volume encryption key.
4. A folder named secure_volume (or a custom name) is automatically created and locked with a dspv.meta file.

2. Accessing Files

Once unlocked, DSPV hosts a local WebDAV server acting as a gateway.

• Windows: A network drive window opens automatically. Drag, drop, and edit files directly.
• Linux / macOS: The server starts at http://127.0.0.1:8080.
  • Linux: Mount using davfs2 or your file manager's "Connect to Server" feature (dav://127.0.0.1:8080).
  • macOS: Open Finder → Go → Connect to Server → http://localhost:8080.

Note: Automatic native mounting for Linux and macOS is currently being refined.

3. Closing the Vault

Simply press CTRL+C in the terminal running DSPV. The server will gracefully shut down, flush all pending operations to disk, and purge the RAM.
