Security | Tor 0.2.5

Tor is free software and an open network that helps you defend against a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security known as traffic analysis.

Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. Tor works with many of your existing applications, including web browsers, instant messaging clients, remote login, and other applications based on the TCP protocol.

Hundreds of thousands of people around the world use Tor for a wide variety of reasons: journalists and bloggers, human rights workers, law enforcement officers, soldiers, corporations, citizens of repressive regimes, and just ordinary citizens. See the Who Uses Tor? page for examples of typical Tor users. See the overview page for a more detailed explanation of what Tor does, and why this diversity of users is important.

Tor does not magically encrypt all of your Internet activities. Understand what Tor does and does not do for you. Read more about this topic.

New in this version:
Add support in the Network settings page for configuring the Socks4Proxy and Socks5Proxy* options that were added in Tor 0.2.2.1-alpha. Patch from Christopher Davis.
Add a "Automatically distribute my bridge address" checkbox (enabled by default) to the bridge relay settings options. (Ticket #524)
Add ports 7000 and 7001 to the list of ports excluded by the IRC category in the exit policy configuration tab. (Ticket #517)
Add a context menu for highlighted event items in the "Basic" message log view that allows the user to copy the selected item text to the clipboard.
Maybe fix a time conversion bug that could result in Vidalia displaying the wrong uptime for a relay in the network map.
Stop trying to enforce proper quoting and escaping of arguments to be given to the proxy executable (e.g., Polipo). Now the user is on their own for properly formatting the command line used to start the proxy executable. (Ticket #523)

Requirements:
