Communication / Encrypted Messaging

Signal Protocol Probably one of the most popular, secure private messaging apps that combines strong encryption (see ) with a simple UI and plenty of features. It's widely used across the world, and easy-to-use, functioning similar to WhatsApp - with instant messaging, read-receipts, support for media attachments and allows for high-quality voice and video calls. It's cross-platform, open-source and totally free. Signal is by Edward Snowden, and is a perfect solution for most users
Loki Net Session is a fork of Signal, however unlike Signal it does not require a mobile number (or any other personal data) to register, instead each user is identified by a public key. It is also decentralized, with servers being run by the community though , messages are encrypted and routed through several of these nodes. All communications are E2E encrypted, and there is no meta data
OMEMO end-to-end encryption XMPP, also known as Jabber, is an open standard for decentralized messaging that has been widely used for decades. It has actually been the basis upon which WhatsApp, Facebook's Chat and Google's Talk were built, but these companies (eventually) chose to remove the interoperability with other servers. Prominent XMPP clients support , which is based on the that is used in Signal. For more hands-on information and to register an account you can visit
Element Matrix is a decentralized open network for secure communications, with E2E encryption with Olm and Megolm. Along with the client, it supports VOIP + video calling and IM + group chats.

Chat Secure
KeyBase Allows encrypted real-time chat, group chats, and public and private file sharing. It also has some nice features around cryptographically proving social identities, and makes PGP signing, encrypting and decrypting messages easy. However, since it was in 2020, it has no longer been receiving regular updates
OpenPGP can be used over existing chat networks (such as email or message boards). It provides cryptographic privacy and authentication, PGP is used to encrypt messages. PGP is to use for beginners, and could lead to human error/ mistakes being made, which would be overall much worse than if an alternate, simpler system was used. Do not use - they are too short to be secure. There have also been vulnerabilities found in the OpenPGP and S/MIME, defined in , so although it still considered secure for general purpose use, for general chat, it may be better to use an encrypted messaging or email app instead

Communication / P2P Messaging

… Oxen (previously Loki) is an open source set of tools that allow users to transact and communicate anonymously and privately, through a decentralised, encrypted, onion-based network. Session is a desktop and mobile app that uses these private routing protocols to secure messages, media and metadata

Tuta like other encrypted mail providers, instead they use a standardized, hybrid method consisting of symmetrical and asymmetrical algorithms (with AES256, and RSA 2048 or ECC (x25519) and Kyber-1024). This causes compatibility issues when communicating with contacts using PGP. But it does allow them to encrypt much more of the header data (body, attachments, subject lines, and sender names etc) which PGP mail providers cannot do. The recent upgrades to Tuta's encryption algorithm makes data stored and sent with their service safe against attacks posed by quantum computers
