Note

When a file is encrypted locally—independent of servers and their processes—the responsibility for encryption lies solely with you. This project was created to provide a method of encryption that does not depend on corporations or the methods they use.

RoundAway

RoundAway is a portable cryptographic tool designed for secure and private communication. Built with Electron and Node.js, it provides encrypted messaging and file exchange capabilities in a lightweight desktop application.

🚀 Getting Started

1. Install dependencies

# Enter this in the terminal / PowerShell
npm install

2. Run in development mode

# Enter this in the terminal / PowerShell
npm start

🏗️ Build Instructions

To create a production build:

# Create a build for Windows
npm run build:win
# Create a build for Linux
npm run build:linux 

The final output will be generated in the /dist directory.

🔐 Encryption Algorithms & Methods

RoundAway supports multiple symmetric encryption algorithms:

Algorithm	Key Size	Mode	Notes
AES-256-GCM	256-bit	GCM	Recommended
AES-192-GCM	192-bit	GCM
AES-128-GCM	128-bit	GCM
AES-256-CBC	256-bit	CBC	Default
AES-192-CBC	192-bit	CBC
AES-128-CBC	128-bit	CBC
CAMELLIA-256	256-bit	CBC	ISO standard
ChaCha20	256-bit	Stream	Used in TLS 1.3

🔑 RSA Key Management

• private.pem — Private key (keep secret, never share)
• public.pem — Public key (safe to distribute)
