🛡️ V-Shield - Secure files as hidden video

🚀 Getting Started

V-Shield lets you turn a file into a visual stream and store it on YouTube. It keeps the file encrypted and corrects errors so the data can survive video compression and scaling.

Use it if you want to:

• hide a file inside a video-like stream
• protect content with strong encryption
• keep control of your data without a server
• work with files such as videos, archives, and documents

📥 Download and Install

1. Open the V-Shield releases page
2. Download the latest Windows file from the release assets
3. If the download comes as a .zip file, extract it first
4. Open the extracted folder
5. Run the .exe file to start V-Shield

If Windows asks for permission, choose Yes.

🖥️ Windows Setup

V-Shield runs as a desktop app on Windows. For best results:

• Use Windows 10 or Windows 11
• Keep at least 200 MB of free disk space
• Make sure you have a stable internet connection for uploads
• Use a modern browser if the app opens web pages during setup

If you have trouble opening the app:

• Right-click the .exe file and choose Run as administrator
• Check whether your antivirus moved the file to quarantine
• Download the release again if the file looks incomplete

🔐 What V-Shield Does

V-Shield takes your file and turns it into a structured visual stream. Then it sends that stream to YouTube.

It is built to:

• encrypt your file before upload
• split data into chunks
• correct errors if parts of the stream change
• handle compression from H.264
• handle chroma subsampling
• handle downscaling by the platform

That means the content can survive the trip through a video site and come back in one piece.

🧭 How It Works

1. Pick a file on your PC
2. V-Shield encrypts it with a strong key
3. The app turns the data into visual noise
4. It adds error correction data
5. You upload the result to YouTube
6. Later, V-Shield reads the stream back and decrypts it

You do not need to manage a server or a database. The file stays in your control.

📁 Best File Types

V-Shield can work with many file types, including:

• .mp4, .mov, .mkv
• .zip, .7z, .rar
• .pdf, .docx, .xlsx
• images, text files, and backups

Large files may take longer to encode and upload. Smaller files are easier to test first.

🛠️ Basic Use

1. Open the app

Start V-Shield from the Windows menu or from the folder where you extracted it

2. Choose a file

Select the file you want to protect and upload

3. Set a key

Create a password or key you can keep safe. You will need it to recover the file

4. Start encoding

The app will turn your file into a stream that can be uploaded

5. Upload to YouTube

Follow the app prompt to send the output to YouTube

6. Recover the file later

Open the stream in V-Shield, enter the same key, and restore the file

🔎 Key Points to Keep in Mind

• Keep your key safe
• Use the same key for restore
• Store the original file name if you want it back later
• Test with a small file first
• Wait for the full encode process to finish before closing the app

⚙️ Features

• File encryption with ChaCha20
• Error correction with Reed-Solomon
• Browser support through a Firefox extension
• Desktop app built with Tauri
• WebAssembly support for fast processing
• Designed for YouTube transport
• Zero-knowledge style workflow

🧩 Recommended Workflow

For the smoothest first run:

1. Download the release
2. Extract the files
3. Run the app
4. Encode a small ZIP file
5. Upload it
6. Check that you can restore it with the same key

This helps you learn the flow before you use a large file.

🧪 Troubleshooting

The app does not open

• Make sure you downloaded the Windows release file
• Reboot your PC and try again
• Run the .exe file from the extracted folder
• Check that Windows SmartScreen did not block it

The upload fails

• Check your internet connection
• Try a smaller file
• Confirm that YouTube login is active in your browser
• Close and reopen the app, then try again

The restored file is broken

• Use the same key you used during encode
• Make sure the upload finished fully
• Try the original stream again
• Start with a smaller test file to confirm your setup

The file plays but does not decode

• Confirm that the uploaded video was not edited
• Avoid re-saving the file after upload
• Use the exact output from V-Shield
• Check that the extension or companion tool is active if your setup uses one

🧷 Tips for Safe Use

• Use a private browser profile if you want less sign-in clutter
• Keep a backup of the key in a safe place
• Use short test runs before large uploads
• Avoid changing the uploaded video after it leaves V-Shield
• Keep your release files in one folder so you can find them fast

📌 For the Best Results

V-Shield works best when you:

• upload the stream without edits
• keep the same settings for encode and decode
• use a clean install on Windows
• avoid file renaming after upload unless the app tells you to do it
