2. Nowadays , in our fast developing world, Information – the most valuable thing . People are swimming in this infinity flow of

information every moment. Everything
around us is information.
Our life is determined by information . So
that
those ,who can control and administrate
it , are the real owners of the world and
our lives .
In Orwell’s“1984” we can see absolute
power and authority in hand of the
government . The reason of their
absolute power is ability to control all
information that people receive. So that
even this senseless and absurd phrases
had their own place.

Signal uses Curve25519, AES-256, and HMAC-SHA256. The security of these algorithms has been tested over many years of use in hundreds of
different applications. Messages sent via Signal are end-to-end encrypted, which means that they can only be read by your intended recipients.
We make it easy for you to verify that you are communicating with the right people and that no MITM attack has occurred. The keys that are
used to encrypt your messages are stored on your device alone, and they are protected by an additional layer of encryption if you have a
passphrase enabled.
Open WhisperSystems does not have access to the contents of any messages sent by Signal users. Additionally, the complete source code for
the Signal clients and the Signal server is available on GitHub.
