Signal<\/a><\/h1>

Signal<\/a> is a cross-platform encrypted messaging service developed by the Signal-Foundation<\/a> and Signal-Messenger-LLC<\/a>. It is widely considered the industry standard for secure communication due to its use of End-to-End-Encryption<\/a>. The application is recommended by high-profile privacy advocates such as Edward-Snowden<\/a> and Jack-Dorsey<\/a> for its commitment to user anonymity and data protection.<\/p>

The Signal Protocol<\/h2>

The foundation of the app's security is the Signal-Protocol<\/a>, a cryptographic protocol that was previously known as the TextSecure Protocol. It combines the Double-Ratchet-Algorithm<\/a> with a Triple Diffie-Hellman handshake. According to the Signal Technical Documentation<\/a>, this ensures that every message has a unique key, providing perfect forward secrecy. This technology has been adopted by other platforms, including WhatsApp<\/a> and Google-Messages<\/a>.<\/p>

History and Governance<\/h2>

The service was created by Moxie-Marlinspike<\/a>, a security researcher who founded Whisper Systems. In 2018, Brian-Acton<\/a>, the co-founder of WhatsApp<\/a>, provided $50 million in funding to establish the Signal-Foundation<\/a> as a non-profit organization. As reported by Wired<\/a>, this move was intended to ensure that the development of Signal<\/a> remains independent of corporate influence or advertising revenue.<\/p>

Transparency and Open Source<\/h2>

One of the key advantages of Signal<\/a> is that it is Open-Source-Software<\/a>. The client and server code are publicly available for audit on the official Signal GitHub<\/a>. This transparency allows the Cybersecurity<\/a> community to verify that the software does not contain backdoors. Unlike many competitors, Signal<\/a> collects minimal metadata, storing only the date of account creation and the last date of connection.<\/p>
