A cypherpunk is any individual advocating widespread use of strong cryptography and privacy-enhancing technologies as a route to social and political change. Originally communicating through the Cypherpunks electronic mailing list, informal groups aimed to achieve privacy and security through proactive use of cryptography. Cypherpunks have been engaged in an active movement since at least the late 1980s.
Instant messaging (IM) technology is a type of online chat allowing real-time text transmission over the Internet or another computer network. Messages are typically transmitted between two or more parties, when each user inputs text and triggers a transmission to the recipient(s), who are all connected on a common network. It differs from email in that conversations over instant messaging happen in real-time. Most modern IM applications use push technology and also add other features such as emojis, file transfer, chatbots, voice over IP, or video chat capabilities.
Bernstein v. United States is a set of court cases brought by Daniel J. Bernstein challenging restrictions on the export of cryptography from the United States.
End-to-end encryption (E2EE) is a security method that keeps chats and messages secure. The end-to-end encryption is a system of communication where only the users communicating can read the messages. In principle, it prevents potential eavesdroppers – including telecom providers, Internet providers, malicious actors, and even the provider of the communication service – from being able to access the cryptographic keys needed to decrypt the conversation.
Adobe Digital Editions is an e-book reader software program from Adobe Systems, built initially using Adobe Flash. It is used for acquiring, managing, and reading e-books, digital newspapers, and other digital publications. The software supports EPUB and PDF. It implements a proprietary scheme of digital rights management (DRM) which, since the version 1.5 release in May 2008, allows document sharing among multiple devices and user authentication via an Adobe ID. Digital Editions is a successor to the Acrobat eBook Reader application.
The Electronic Frontier Foundation (EFF) is an international non-profit digital rights group based in San Francisco, California. The foundation was formed on 10 July 1990 by John Gilmore, John Perry Barlow and Mitch Kapor to promote Internet civil liberties.

WhatsApp is an internationally available freeware, cross-platform, centralized instant messaging (IM) and voice-over-IP (VoIP) service owned by US tech conglomerate Meta. It allows users to send text and voice messages, make voice and video calls, and share images, documents, user locations, and other content. WhatsApp's client application runs on mobile devices, and can be accessed from computers. The service requires a cellular mobile telephone number to sign up. In January 2018, WhatsApp released a standalone business app called WhatsApp Business which can communicate with the standard WhatsApp client.
Messenger is an American proprietary instant messaging app and platform developed by Meta Platforms. Originally developed as Facebook Chat in 2008, the company revamped its messaging service in 2010, released standalone iOS and Android apps in 2011, and released standalone Facebook Portal hardware for Messenger calling in 2018. In April 2015, Facebook launched a dedicated website interface, Messenger.com, and separated the messaging functionality from the main Facebook app, allowing users to use the web interface or download one of the standalone apps. In April 2020, Facebook released a Messenger desktop app for Windows and macOS.
CryptoParty (Crypto-Party) is a grassroots global endeavour to introduce the basics of practical cryptography such as the Tor anonymity network, I2P, Freenet, key signing parties, disk encryption and virtual private networks to the general public. The project primarily consists of a series of free public workshops.
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.
Open Whisper Systems was a software development group that was founded by Moxie Marlinspike in 2013. The group picked up the open source development of TextSecure and RedPhone, and was later responsible for starting the development of the Signal Protocol and the Signal messaging app. In 2018, Signal Messenger was incorporated as an LLC by Moxie Marlinspike and Brian Acton and then rolled under the independent 501c3 non-profit Signal Technology Foundation. Today, the Signal app is developed by Signal Messenger LLC, which is funded by the Signal Technology Foundation.
HTTPS Everywhere is a discontinued free and open-source browser extension for Google Chrome, Microsoft Edge, Mozilla Firefox, Opera, Brave, Vivaldi and Firefox for Android, which is developed collaboratively by The Tor Project and the Electronic Frontier Foundation (EFF). It automatically makes websites use a more secure HTTPS connection instead of HTTP, if they support it. The option "Encrypt All Sites Eligible" makes it possible to block and unblock all non-HTTPS browser connections with one click. Due to the widespread adoption of HTTPS on the World Wide Web, and the integration of HTTPS-only mode on major browsers, the extension was retired in January 2023.
Disconnect is a partly open source browser extension and mobile app designed to stop non-consensual third party trackers, and providing private web search and private web browsing. On mobile, it is available for Android and iPhone. It was developed by Brian Kennish and Casey Oppenheim. Disconnect-Search had once been the default search engine of the security-focused Tor Browser, which now uses DuckDuckGo.
Eva Galperin is the Director of Cybersecurity at the Electronic Frontier Foundation (EFF) and technical advisor for the Freedom of the Press Foundation. She is noted for her extensive work in protecting global privacy and free speech and for her research on malware and nation-state spyware.
This article provides a detailed chronological account of the historical reception and criticism of security and privacy features in the WhatsApp messaging service.
