Comunicación en tiempo real material/chat-processing Other instant messengers make all of your private conversations available to the company that runs them.

Estas son nuestras recomendaciones para la comunicación cifrada en tiempo real.

Mensajeros multiplataforma

These messengers are great for securing your sensitive communications.

Signal

!!! recomendación

![Logotipo de Signal](assets/img/messengers/signal.svg){ align=right }

**Signal** es una aplicación móvil desarrollada por Signal Messenger LLC. La aplicación ofrece mensajería instantánea, así como llamadas de voz y vídeo.

Todas las comunicaciones son E2EE. Las listas de contactos se encriptan con tu PIN de Signal y el servidor no tiene acceso a ellas. Los perfiles personales también están encriptados y sólo se comparten con los contactos con los que chateas.

El protocolo fue auditado de forma independiente en 2016. La especificación del protocolo Signal puede encontrarse en su documentación. Signal has minimal metadata when Sealed Sender is enabled. The sender address is encrypted along with the message body, and only the recipient address is visible to the server. Sealed Sender is only enabled for people in your contacts list, but can be enabled for all recipients with the increased risk of receiving spam. Signal requires your phone number as a personal identifier.

The protocol was independently audited in 2016. The specification for the Signal protocol can be found in their documentation.

We have some additional tips on configuring and hardening your Signal installation:

SimpleX Chat

!!! recomendación

![Logotipo de Element](assets/img/messengers/element.svg){ align=right }

**Element** es el cliente de referencia para el protocolo [Matrix](https://matrix.org/docs/guides/introduction), un [estándar abierto](https://matrix.org/docs/spec) para la comunicación segura descentralizada en tiempo real. Los mensajes y los archivos compartidos en las salas privadas (las que requieren una invitación) son por defecto E2EE, al igual que las llamadas de voz y vídeo uno a uno.

SimpleX Chat was audited by Trail of Bits in October 2022.

Currently SimpleX Chat only provides a client for Android and iOS. La especificación del protocolo Matrix puede encontrarse en su documentación. El trinquete criptográfico Olm utilizado por Matrix es una implementación del algoritmo de doble trinquete de Signal.

Your data can be exported, and imported onto another device, as there are no central servers where this is backed up.

Briar

!!! recomendación

![Logotipo de Session](assets/img/messengers/session.svg){ align=right }

**Session** es un mensajero descentralizado con un foco en las comunicaciones privadas, seguras y anónimas. Session soporta los mensajes directos, chats de grupo y llamadas de voz. Session utiliza la red descentralizada [Oxen Service Node Network](https://oxen.io/) para almacenar y enrutar los mensajes.

Cada mensaje encriptado pasa por tres nodos de una red llamada "Red de Nodos de Servicio Oxen", lo que hace prácticamente imposible que los nodos recopilen información significativa sobre quienes utilizan la red. downloads

    - [:simple-flathub: Flathub](https://flathub.org/apps/details/org.briarproject.Briar)

To add a contact on Briar, you must both add each other first. You can either exchange briar:// links or scan a contacts QR code if they are nearby.

The client software was independently audited, and the anonymous routing protocol uses the Tor network which has also been audited.

Briar has a fully published specification.

Briar supports perfect forward secrecy by using the Bramble Handshake and Transport protocol.

Otros mensajeros

!!! warning

These messengers do not have Perfect [Forward Secrecy](https://en.wikipedia.org/wiki/Forward_secrecy) (PFS), and while they fulfill certain needs that our previous recommendations may not, we do not recommend them for long-term or sensitive communications. Briar también puede conectarse a través de Wi-Fi o Bluetooth cuando está cerca.

Element

!!! recomendación

![Element logo](assets/img/messengers/element.svg){ align=right }

**Element** is the reference client for the [Matrix](https://matrix.org/docs/guides/introduction) protocol, an [open standard](https://matrix.org/docs/spec) for secure decentralized real-time communication.

Messages and files shared in private rooms (those which require an invite) are by default E2EE as are one to one voice and video calls.

Briar tiene una especificación publicada completamente.

Group voice and video calls are not E2EE, and use Jitsi, but this is expected to change with Native Group VoIP Signalling. Group calls have no authentication currently, meaning that non-room participants can also join the calls. We recommend that you do not use this feature for private meetings.

The Matrix protocol itself theoretically supports PFS, however this is not currently supported in Element due to it breaking some aspects of the user experience such as key backups and shared message history.

The protocol was independently audited in 2016. The specification for the Matrix protocol can be found in their documentation. The Olm cryptographic ratchet used by Matrix is an implementation of Signals Double Ratchet algorithm.

Session

!!! recomendación

![Session logo](assets/img/messengers/session.svg){ align=right }

**Session** is a decentralized messenger with a focus on private, secure, and anonymous communications. Session offers support for direct messages, group chats, and voice calls.

Session uses the decentralized [Oxen Service Node Network](https://oxen.io/) to store and route messages. Every encrypted message is routed through three nodes in the Oxen Service Node Network, making it virtually impossible for the nodes to compile meaningful information on those using the network.

    - [:simple-apple: macOS](https://getsession.org/download)
    - [:simple-linux: Linux](https://getsession.org/download)

Session allows for E2EE in one-on-one chats or closed groups which allow for up to 100 members. Open groups have no restriction on the number of members, but are open by design.

Session does not support PFS, which is when an encryption system automatically and frequently changes the keys it uses to encrypt and decrypt information, such that if the latest key is compromised it exposes a smaller portion of sensitive information.

Oxen requested an independent audit for Session in March of 2020. The audit concluded in April of 2021, “The overall security level of this application is good and makes it usable for privacy-concerned people.”

Session has a whitepaper describing the technicals of the app and protocol.

Criteria

Please note we are not affiliated with any of the projects we recommend. In addition to our standard criteria, we have developed a clear set of requirements to allow us to provide objective recommendations. We suggest you familiarize yourself with this list before choosing to use a project, and conduct your own research to ensure it's the right choice for you.

!!! example "This section is new"

We are working on establishing defined criteria for every section of our site, and this may be subject to change. If you have any questions about our criteria, please [ask on our forum](https://discuss.privacyguides.net/latest) and don't assume we didn't consider something when making our recommendations if it is not listed here. There are many factors considered and discussed when we recommend a project, and documenting every single one is a work-in-progress.
  • Must have open-source clients.
  • Must use E2EE for private messages by default.
  • Must support E2EE for all messages.
  • Must have been independently audited.

Best-Case

Our best-case criteria represents what we would like to see from the perfect project in this category. Our recommendations may not include any or all of this functionality, but those which do may rank higher than others on this page.

  • Should have Perfect Forward Secrecy.
  • Should have open-source servers.
  • Should be decentralized, i.e. federated or P2P.
  • Should use E2EE for all messages by default.
  • Should support Linux, macOS, Windows, Android, and iOS.
