How OnionShare Works

At its core, OnionShareOnionShare is an open-source tool that lets people share files, host websites, and even chat securely through the Tor network. Instead of relying on cloud services, it creates a temporary onion address directly from your computer, ensuring anonymity and direct peer-to-peer transfers.

When a user starts the application:

• A temporary local server runs directly on their computer.
• The app generates a unique onion address, valid only while the server is active.
• This address can be shared with a recipient, who then downloads the files via the Tor Browser.

Key Features:

• Direct connection between sender and receiver — no central servers.
• One-time links — once the transfer is finished or the app closes, the link no longer works.
• Mutual protection — both parties’ IP addresses remain hidden behind Tor.
