Warning: The Android operating system provided with phones and tablets is often modified with the addition of proprietary applications from Google or others and may compromise your privacy. We strongly recommend replacing it with Replicant (or compile Android from source for your device).

Bitmessage es una alternativa prometedora al correo electrónico, pero aún no está lista para su uso diario. Úsala bajo tu propio riesgo.Riseup está hospedado en los Estados Unidos. También comienza a ofrecer servicios de VPN, chat, y Etherpad.¿Por qué no Hushmail? Revisa este artículo en inglés sobre los “compromisos a la privacidad de los correos”.La única forma de tener pleno control sobre tu correo es correr tu propio servidor de correo. Esto no es posible para todos, sin embargo, ya que requiere una considerable inversión de tiempo y conocimiento técnico.Aunque aún no está completo, el proyecto FreedomBox busca crear una solución de fácil arranque para comunicaciones cifradas.

Email Alternatives
Notes

Bitmessage is a promising alternative to email, but it has not yet been audited by security professionals. Use at your own risk. If you decide to try out Bitmessage, make sure to generate a completely random ID to greatly reduce the probability of ID collisions.

RetroShare has not been thoroughly audited by security professionals for possible security issues.

Email Clients
Notes

Switching from a proprietary service like Gmail to one of the more transparently-run email services on PRISM Break is the first step to a secure email account.

The second step is getting you and your contacts to encrypt your plain text messages with PGP encryption. This section contains free email clients that support PGP.

Read the Email Self-Defense guide by the Free Software Foundation to learn how to encrypt your email messages.

Here is a guide by Security In A Box to encrypting your email with Mozilla Thunderbird, GNU Privacy Guard (GPG), and Enigmail.

Find out more about the differences between Mozilla Thunderbird and Icedove.

“Off-the-Record Messaging, commonly referred to as OTR, is a cryptographic protocol that provides strong encryption for instant messaging conversations. OTR uses a combination of the AES symmetric-key algorithm, the Diffie–Hellman key exchange, and the SHA-1 hash function. In addition to authentication and encryption, OTR provides perfect forward secrecy and malleable encryption.

The primary motivation behind the protocol was providing deniability for the conversation participants while keeping conversations confidential, like a private conversation in real life, or off the record in journalism sourcing.”

Kolab integrates Roundcube into its webclient and offers desktop clients as well. Recent versions also feature a file cloud turning it into a complete solution for personal information management.

What is an MTA?

“Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. An MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol.

The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.”

Una xarxa mesh és una xarxa descentralitzada d'igual a igual, amb enllaços físics controlats pels usuaris, normalment sense fils.“Les xarxes mesh (com a topologia) són un tipus de xarxa on cada node no només ha de capturar i dissemniar la seva propia informació, sino també servir com a pont per a altres nodes, és a dir, ha de col·laborar per propagar la informació a la xarxa.“Wikipedia (en anglès)

Installing your own add-ons into Tor Browser is not recommended, as they may bypass Tor or otherwise harm your anonymity and privacy. Check the EFF's Panopticlick to see how trackable your browser configuration is by third parties.

If you're using a Firefox-based browser, you can safeguard your browsing habits and stop advertising companies from tracking you by installing uBlock Origin, Request Policy, and HTTPS Everywhere.

A more advanced alternative to Request Policy would be uMatrix.

Install NoScript and enable ‘Forbid scripts globally’ to improve the security of your browser by preventing 0day JavaScript attacks. This is a drastic option as it will render many websites unusable as they rely heavily on JavaScript. NoScript offers a whitelist you can use to selectively enable JavaScript for sites you trust, but this is considered especially bad for your anonymity if you're using NoScript with Tor Browser.

Why is Adblock Plus not recommended? Adblock Plus shows “acceptable ads” by default, which works against the purpose of the add-on. Either disable acceptable ads or use uBlock Origin instead.

Web Browsers
Notes
Usa una combinación de Tor Browser y un navegador web libre de tu elección para navegar por la red. Intenta usar Tor Browser tan a menudo como sea posible. La navegación es más lenta con Tor, pero mucho más segura. Nota: Mozilla Firefox técnicamente no es completamente software libre, ya que Mozilla recomienda agregados no libres en su página web.
