# Secure File Manager
A cryptographic file operations tool with a CLI and an Electron desktop GUI.
## Features
- **Encrypt** — AES-256-CBC file encryption with random IV and key
- **Decrypt** — AES-256-CBC file decryption using stored key/IV
- **Hash** — SHA-256 file hashing
- **Sign** — RSA digital signature creation
- **Verify** — RSA signature verification
## Screenshots
The Electron GUI uses a cyberpunk-themed dark interface with neon accent colors, CRT scanline effects, and native file browse dialogs.
## Prerequisites
- **Visual Studio 2022** (MSVC C++17 compiler)
- **CMake 3.10+**
- **OpenSSL 3.x** — installed at `C:\Program Files\OpenSSL-Win64`
- **Node.js 18+** — for the Electron GUI
- **Windows 10 SDK**
## Building the CLI
Open a **Developer Command Prompt for VS 2022** and run:
```bash
cmake -S . -B build -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=Release -DOPENSSL_ROOT_DIR="C:\Program Files\OpenSSL-Win64"
cmake --build build --target secure_file_manager
```
Or with the Visual Studio generator:
```bash
cmake -S . -B build -G "Visual Studio 17 2022" -A x64
cmake --build build --config Release --target secure_file_manager
```
## CLI Usage
```bash
secure_file_manager encrypt
secure_file_manager decrypt
secure_file_manager hash
secure_file_manager sign
secure_file_manager verify
```
- Encryption generates `key_iv.bin` in the working directory (required for decryption)
- Signing requires `private.pem` in the working directory
- Verification requires `public.pem` in the working directory
## Electron GUI
The desktop GUI wraps the CLI with a cyberpunk-themed interface built on Electron.
### Setup
```bash
cd gui
npm install
```
### Launch
```bash
unset ELECTRON_RUN_AS_NODE
npm start
```
> **Note:** VS Code's integrated terminal sets `ELECTRON_RUN_AS_NODE=1` which prevents Electron from launching as a desktop app. Run `unset ELECTRON_RUN_AS_NODE` first, or use a standalone terminal.
The GUI spawns the compiled CLI executable (`build/secure_file_manager.exe`) for all cryptographic operations. Make sure the CLI is built before launching the GUI.
## Running Tests
```bash
cmake --build build --target test_crypto
./build/test_crypto
```
This runs a basic roundtrip test: creates a file, encrypts it, decrypts it, and verifies the output matches the original.
