Magic Wormhole – A Simple And Secure Way To Send Files From Linux Command Line

Jonathan MathewsPublic

Meet Magic Wormhole is a simple and free utility that help users to send a files from one computer to another computer anywhere in the world.

It’s a fast and secure way to send files to Linux and macOS users. Even newbies can send files through wormhole easily since it doesn’t require any techi knowledge and offers very simple syntax.

If you want to send a file over the internet to someone, either you have to send an email or upload into any cloud-based service. If you don’t trust these and want to send a file directly to someone securely without intermediaries, what to do? that’s what SPAKE2 came to picture.

How to do? You just open a terminal and type wormhole command then send and finally add a File which you want to send that’s it. It will generate a one time human readable code, which needs to be apply while receiving the file on destination user end.

We can send text, files and folders (It can be automatically zipped) through wormhole. The two endpoints (Source and Destination computers) are identified by using identical “wormhole codes”: in general, the sending machine generates and displays the code, which must then be typed into the receiving machine.

Even it’s human readable, the receiving end no need to type full code since it’s offers tab-completion on the codewords, so type few characters then double press tab to complete the code.

It uses SPAKE2 is a Password authenticated key exchange (PAKE) protocol that allows parties that use the same password to negotiate and authenticate a shared key or session key (“key exchange”). It’s a cryptographic algorithms that uses a short low-entropy password to establish a strong high-entropy shared key, also used to encrypt data.

The program does not have any built-in timeouts, however it is expected that both clients will be run within an hour. Both users get a notification in terminal during and after the file transfer is complete.
