magic-wormhole is a command-line utility that belongs to the secure file-transfer category and is designed to let users move files, folders, or arbitrary text from one computer to another without exposing the data to intermediate servers or eavesdroppers. Developed under the same “magic-wormhole” publisher name, the program employs PAKE-based cryptography to establish a direct, encrypted tunnel between sender and receiver; only a short, human-pronounceable code word has to be exchanged out-of-band, after which the transfer proceeds automatically. Typical use cases include quickly sending a large video from a laptop to a colleague’s workstation across the office, mirroring configuration files between a local machine and a remote VM, or sharing password archives with a friend without relying on cloud storage. Because the tool is packaged both as a Python library and as a standalone executable, it can be scripted into CI pipelines, integrated into backup routines, or invoked ad-hoc from any terminal. Since its first public appearance the project has undergone fifteen documented releases; the current stable line is represented by version 0.22.0.1, while earlier iterations remain accessible for environments that require specific protocol behaviors or legacy Python compatibility. All versions maintain backward-compatible command syntax and continue to support optional “transit relay” servers for situations where direct NAT traversal fails. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
