Delta Chat: The free and open email-based messaging app

In these days of so much technological concern, especially in terms of computer security, privacy and anonymity, for news about flaws or vulnerabilities of communication and / or messaging applications, such as, WhatsApp, a quite interesting alternative arises, called Delta Cat.

Interesting, because Delta Cat It is a new messaging application, which unlike other very popular, send your messages by email, encrypted if possible, with autocrypt. And between other things, does not require its users to register somewhere or site, since, with an existing email account, their service can be used.

Delta Chat: Introduction

We recently posted about another interesting messaging application, as an alternative to Telegram o WhatsAppCalled Session. Which, differed from these, because:

"Session is an open source, public key-based secure messaging application that uses a set of decentralized storage servers and an onion routing protocol to send end-to-end encrypted messages with minimal exposure of user metadata. It does so while providing the common features of the main messaging apps".

Delta Cat, also has decentralized characteristics, since it has a centralized controlIn other words, it uses the largest, most diverse and decentralized communication system ever created: the existing network of email servers.
