corkscrew é uma ferramenta simples para encapsular conexões TCP através de um proxy HTTP suportando o método CONNECT. Ele lê da entrada padrão ("stdin") e escreve na saída padrão ("stdout") durante a conexão, exatamente como o netcat.

Ele pode ser usado por exemplo para conectar em um servidor SSH executando em uma porta 443 remota através de um proxy HTTPS estrito.

GNUnet is a peer-to-peer framework which focuses on providing security. All link-to-link messages in the network are confidential and authenticated. The framework provides a transport abstraction layer and can currently encapsulate the peer-to-peer traffic in UDP, TCP, or SMTP messages.

This is a piece of software that lets you tunnel IPv4 data through a DNS server. This can be usable in different situations where internet access is firewalled, but DNS queries are allowed.

iodine is similar to nstx but has password authentication, brings up the tun interface automatically and lets the user specify the IP address as a command line option.

GNU MAC Changer is an utility that makes the maniputation of MAC addresses of network interfaces easier. MAC addresses are unique identifiers on networks, they only need to be unique, they can be changed on most network hardware. MAC addresses have started to be abused by unscrupulous marketing firms, government agencies, and others to provide an easy way to track a computer across multiple networks. By changing the MAC address regularly, this kind of tracking can be thwarted, or at least made a lot more difficult.

Features:

• set specific MAC address of a network interface
• set the MAC randomly
• set a MAC of another vendor
• set another MAC of the same vendor
• set a MAC of the same kind (eg: wireless card)
• display a vendor MAC list (today, 6200 items) to choose from

Metadata consist of information that characterizes data. Metadata are used to provide documentation for data products. In essence, metadata answer who, what, when, where, why, and how about every facet of the data that are being documented.

Metadata within a file can tell a lot about you. Cameras record data about when a picture was taken and what camera was used. Office documents like PDF or Office automatically adds author and company information to documents and spreadsheets.

Maybe you don't want to disclose those information on the web.

Mat only removes metadata from your files, it does not anonymise their content, nor can it handle watermarking, steganography, or any too custom metadata field/system.

If you really want to be anonym, use format that does not contain any metadata, or better: use plain-text.

Formats supported to some extent are:

• Portable Network Graphics (PNG)
• JPEG (.jpeg, .jpg, ...)
• Open Document (.odt, .odx, .ods, ...)
• Office Openxml (.docx, .pptx, .xlsx, ...)
• Portable Document Fileformat (.pdf)
• Tape ARchive (.tar, .tar.bz2, .tar.gz)
• ZIP (.zip)
• MPEG Audio (.mp3, .mp2, .mp1, .mpa)
• Ogg Vorbis (.ogg)
• Free Lossless Audio Codec (.flac)
• Torrent (.torrent)

This is a transitional dummy package to ease the migration from the mozilla-noscript to the new xul-ext-noscript package. You can remove it safely.

obfs4proxy is a tool that attempts to circumvent censorship by transforming the Tor traffic between the client and the bridge. This way censors, who usually monitor traffic between the client and the bridge, will see innocent-looking transformed traffic instead of the actual Tor traffic.

obfs4proxy implements the obfsucation protocols obfs2, obfs3, and obfs4.

It is written in Go and is compliant with the Tor pluggable transports specification, and its modular architecture allows it to support multiple pluggable transports.

OnionCat creates a transparent IP layer on top of Tor hidden services. It transparently transmits any kind of IP-based data through the Tor network on a location hidden basis. You can think of it as a point-to-multipoint VPN between hidden services.

OnionCat is a stand-alone application which runs in userland and is a connector between Tor and the local OS. Any protocol based on IP, such as UDP or TCP, can be transmitted.

OnionCat supports IPv6; native IPv4 forwarding, though still available, is deprecated: the recommended solution for IPv4 forwarding is to build a IPv4-through-IPv6 tunnel through OnionCat.

OpenVPN é uma aplicação para fazer um túnel de redes de IP sobre uma porta UDP ou TCP única com segurança. Pode ser usado para acessar locais remotos, fazer conexões ponto-a-ponto seguras, melhorar a segurança de redes sem fio, etc.

OpenVPN usa toda a encriptação, autenticação e certificação fornecida pela biblioteca OpenSSL (qualquer cifra, tamanho da chave, ou resumo HMAC).

OpenVPN pode usar chaves pré-compartilhadas estáticas, ou troca de chaves dinâmicas baseada em TLS. Também suporta VPNs com endpoints dinâmicos (clientes DHCP ou dial-up), túneis sobre NAT ou firewall com estado orientadas a conexão (como o iptables do Linux).

Privoxy is a web proxy with advanced filtering capabilities for protecting privacy, filtering web page content, managing cookies, controlling access, and removing ads, banners, pop-ups and other obnoxious Internet junk. Privoxy has a very flexible configuration and can be customized to suit individual needs and tastes. Privoxy has application for both stand-alone systems and multi-user networks.

Privoxy is based on Internet Junkbuster (tm).

Tor é um sistema de comunicação anônimo basedo em conexão de baixa latência.

Os clientes escolhem um caminho roteado na origem através de um conjunto de servidores proxy da rede Tor e negociam um "circuito virtual" através da rede, em que cada servidor proxy conhece seu antecessor e sucessor, mas não outros. O tráfego flui para baixo, o circuito é descriptografado em cada servidor proxy, o que revela o servidor proxy do fluxo de download.

Basicamente, Tor fornece uma rede distribuída de servidores proxy. Usuários enviam seus fluxos de dados TCP (tráfego web, ftp, ssh etc) ao redor destes servidores e os destinatários, observadores, e até mesmo os próprios servidores proxy tem dificuldades de aprender sobre quais usuários estão conectados e quais seus destinos.

Este pacote permite apenas um cliente Tor por padrão, mas ele também pode ser configurado facilmente como um proxy e/ou um serviço oculto.

Os aplicativos clientes podem utilizar a rede Tor conectando-se à interface proxy de soquete local fornecida pela sua instância do Tor. Se o aplicativo em si não vier com suporte a soquetes, você pode utilizar um cliente que faça uso de soquetes como o torsocks.

Note que o Tor não realiza limpeza de protocolo sobre o tráfego do aplicativo. Existe o perigo de que os protocolos dos aplicativos e programas relacionados possam ser induzidos a revelar informações sobre o usuário. Tor depende do Torbutton e limpadores de protocolos similares para resolver este problema. Para melhorar a proteção quando navega na web, o Projeto Tor recomenda que você utilize o pacote referente ao navegador Tor, isto é, um arquivo tarball autônomo que inclui versões estáticas do Tor, Torbutton e um Firefox modificado que foi melhorado para corrigir uma variedade de problemas de privacidade.

The anonymizing relay monitor (arm) is a terminal status monitor for Tor relays, intended for command-line aficionados, ssh connections, and anyone stuck with a tty terminal. This works much like top does for system usage, providing real time statistics for:

• bandwidth, cpu, and memory usage
• relay's current configuration
• logged events
• connection details (ip, hostname, fingerprint, and consensus data)
• etc.

This package provides a GeoIP database for Tor, i.e. it maps IPv4 addresses to countries.

Bridge relays (special Tor relays that aren't listed in the main Tor directory) use this information to report which countries they see connections from. These statistics enable the Tor network operators to learn when certain countries start blocking access to bridges.

Clients can also use this to learn what country each relay is in, so Tor controllers like arm or Vidalia can use it, or if they want to configure path selection preferences.

Torsocks permite que você utilize a maioria dos aplicativos que entendem SOCKS de maneira segura com o Tor. Ele garante que as solicitações de DNS são tratadas de forma segura e explicitamente rejeita tráfego UDP a partir do aplicativo que você está utilizando.

Vidalia offers a graphical user interface to start and stop Tor, view its status at a glance, and monitor its bandwidth usage.

Vidalia also makes it easy to contribute to the Tor network by helping you set up a Tor server.

Tor protects privacy in communications via a distributed network of relays run by volunteers all around the world: it prevents anybody watching Internet connections from learning what sites you visit, and it prevents the visited sites from learning your physical location. Tor works with web browsers, instant messaging programs, remote login clients, and many other TCP-based applications.

OnionShare lets you securely and anonymously share a file of any size with someone. It works by starting a web server, making it accessible as a Tor hidden service, and generating an unguessable URL to access and download the file. It doesn't require setting up a server on the Internet somewhere or using a third party filesharing service. You host the file on your own computer and use a Tor hidden service to make it temporarily accessible over the Internet. The other user just needs to use the Tor Browser and to enter the URL to download the file from you.

Tor Browser Launcher is intended to make the Tor Browser Bundle (TBB) easier to maintain and use for GNU/Linux users. torbrowser-launcher handles downloading the most recent version of TBB for you, in your language and for your architecture. It also adds a "Tor Browser" application launcher to your operating system's menu.

When you first launch Tor Browser Launcher, it will download TBB from https://www.torproject.org/ and extract it to ~/.local/share/torbrowser, and then execute it. Cache and configuration files will be stored in ~/.cache/torbrowser and ~/.config/torbrowser. Each subsequent execution after installation will simply launch the most recent TBB. Tor Browser will be fetched, verified and unpacked each time a new version of TBB is released. When you open Tor Browser Launcher after an update, it will download the newer version of TBB for you and extract it over your old TBB directory in ~/.local/share/torbrowser, so you will maintain your TBB bookmarks.
