Hiddencode Project

This workspace contains a minimal implementation matching the provided specification:

• server: Flask server + SQLite database that stores SHA and two codes (upload/download).
• client/Writer: C# WinForms app to write codes for a target file.
• client/Reader: C# WinForms app to scan a folder and read codes for files.

Quick start (macOS / Ubuntu for server):

1. Server

cd server
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
python db_init.py
python app.py

Server listens on http://0.0.0.0:5000 by default.

2. Clients (Windows recommended, requires .NET 6+)

Open client/Writer/Writer.csproj and client/Reader/Reader.csproj in Visual Studio or run:

cd client/Writer
dotnet run

cd ../Reader
dotnet run

Notes:

• Server base URL is http://localhost:5000 in the client code; change if needed.
• The server stores entries in SQLite file server/hiddencode.db with fields: id, sha, upload_code, download_code, created_at.
