Micah Lee, et al.

Micah Lee and the OnionShare contributors maintain a privacy-centric utility that turns the Tor network into a simple drag-and-drop gateway for anonymous file exchange, ephemeral web hosting, and encrypted peer-to-peer chat. OnionShare’s single-window interface lets users of any skill level generate temporary .onion addresses that exist only while the application runs, eliminating the need for permanent servers or cloud accounts. Journalists use it to receive sensitive documents without exposing sources; activists pass large multimedia bundles across borders without leaving logs; lawyers share discovery files under attorney–client privilege; and everyday owners of private data send password-protected folders without trusting third-party clouds. The program can also spin up static website mirrors or real-time chat rooms that vanish once the sender closes the tab, making it a lightweight alternative to rented hosting when anonymity outweighs uptime. Because traffic never leaves the Tor network, both parties remain shielded from network surveillance and correlation attacks, while built-in checksums verify that files arrive unaltered. The project’s open-source codebase invites public scrutiny, and releases are signed so recipients can confirm binary integrity before launching. OnionShare is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always fetch the latest upstream version, and can be queued alongside other applications for unattended batch installation.
