Encrypted Messaging CLI Software

Design Principles

Simplicity in implementation -- ~170 lines of code.
Simplicity in usage.

Why should I use this?

Overall, this is a tutorial example for those interested in a node.js/encryption/sockets.
It's not a "serious" project (at least not yet -- feature requests and contributions are more than welcome).

Is this software really secure?

To the best it can be.

NOTE: This tool has not been audited and is NOT for production use.

Roadmap

• Diffie-Hellman
• zip option for file transfer
• prettier UI
• choice of encryption method
• choice of download location

Prerequisites

Install node.js

Repo https://github.com/maelswarm/whisp-chat.git or npm i whisp-chat

Quickstart

Have both parties decide on two mutual passwords.
These will be used for the AES-256-cfb cipher (used to secure the given parties data transfers).

Command Schema
node app.js --src=<host>:<port> --dest=<destinationhost>:<destinationport> --secret=<password1>:<password2>

Usage

For a quick test, open two terminals on your computer and enter the following commands.

Terminal 1:
node app.js --src=127.0.0.1:4321 --dest=127.0.0.1:1234 --secret=breadandjam:butterybutter

Terminal 2:
node app.js --src=127.0.0.1:1234 --dest=127.0.0.1:4321 --secret=breadandjam:butterybutter

Type text and hit enter.

For sending a file type !file:<filepath> and hit enter.

Do not expect a chat message to be received by the destination while a file transfer is already occuring.
It will be received by the destination after the file transfer.

Files are downloaded into your home directory downloads.
