Signal (software)
Signal is a cross-platform centralized encrypted instant messaging service developed by the non-profit Signal Foundation and its subsidiary, the Signal Messenger LLC. Users can send one-to-one and group messages, which can include files, voice notes, images and videos. It can also be used to make one-to-one and group voice and video calls. The Android version also optionally functions as an SMS app, but this functionality will be removed in 2023. Signal uses standard cellular telephone numbers as identifiers and secures all communications to other Signal users with end-to-end encryption. The client software includes mechanisms by which users can independently verify the identity of their contacts and the integrity of the data channel. Signal's software is free and open-source. Its mobile clients are published under the GPL-3.0-only license, while the desktop client and server are published under the AGPL-3.0-only license.

TextSecure
TextSecure was an encrypted messaging application for Android that was developed from 2010 to 2015. It was a predecessor to Signal and the first application to use the Signal Protocol, which has since been implemented into WhatsApp and other applications. TextSecure used end-to-end encryption to secure the transmission of text messages, group messages, attachments and media messages to other TextSecure users. TextSecure was first developed by Whisper Systems, who were later acqui-hired by Twitter. The application's source code was then released under a free and open-source software license. In 2013, TextSecure's development was picked up by an independent group called Open Whisper Systems, who merged it with an encrypted voice calling application called RedPhone and renamed the product as Signal. History Whisper Systems and Twitter (2010–2011) TextSecure started as an application for sending and receiving encrypted SMS messages. Its beta version was first launched on May ...

Signal Protocol
The Signal Protocol (formerly known as the TextSecure Protocol) is a non- federated cryptographic protocol that can be used to provide end-to-end encryption for voice calls and instant messaging conversations. The protocol was developed by Open Whisper Systems in 2013 and was first introduced in the open-source TextSecure app, which later became Signal. Several closed-source applications have implemented the protocol, such as WhatsApp, which is said to encrypt the conversations of "more than a billion people worldwide" or Google who provides end-to-end encryption by default to all RCS-based conversations between users of their Messages app for one-to-one conversations. Facebook Messenger also say they offer the protocol for optional Secret Conversations, as does Skype for its Private Conversations. The protocol combines the Double Ratchet algorithm, prekeys, and a triple Elliptic-curve Diffie–Hellman (3-DH) handshake, and uses Curve25519, AES-256, and HMAC-SHA256 as primitive ...

Deprecation
In several fields, especially computing, deprecation is the discouragement of use of some terminology, feature, design, or practice, typically because it has been superseded or is no longer considered efficient or safe, without completely removing it or prohibiting its use. Typically, deprecated materials are not completely removed to ensure legacy compatibility or back up practice in case new methods are not functional in an odd scenario. It can also imply that a feature, design, or practice will be removed or discontinued entirely in the future. Etymology In general English usage, the infinitive "to deprecate" means "to express disapproval of (something)". It derives from the Latin verb ''deprecari'', meaning "to ward off (a disaster) by prayer". In current technical usage, for one to state that a feature is deprecated is merely a recommendation against using it. It is still possible to produce a program or product without heeding the deprecation. Software While a deprecated so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Google Allo
Google Allo was an instant messaging mobile app by Google for the Android (operating system), Android and iOS mobile operating systems, with a web client available on Google Chrome, Mozilla Firefox, and Opera (web browser), Opera. It closed on March 12, 2019. The app used phone numbers as identifiers, allowing users to exchange messages, files, voice notes, and images. It included a Virtual assistant (artificial intelligence), virtual assistant that generated automatic reply suggestions and an optional encrypted mode known as incognito mode. Users could also resize messages and add doodles and stickers on images before sending them. Before launch, Google touted strong privacy in the app, with particular emphasis on messages stored "transiently and in non-identifiable form". However, at launch, privacy was significantly rolled back, with Google keeping logs of messages indefinitely (or until the user deletes messages) in an effort to improve the app's "smart reply" feature.
