To this date, WhatsApp is currently world’s largest social messaging app in terms of its user base. It has over more than 1 billion active users each month. In India, alone Whatsapp has over more than 200 million people using it every day. What makes Whatsapp unique other messaging apps is its simplified UI and no ads agenda. It is also famous for its ‘end-to-end encryption’ security provided by default.
End-to-end encryption feature was rolled last year only. This feature basically ensures that each specific WhatsApp messages can only be read by the sender and intended receiver, If someone from middle tries to grab those messages by some special pentesting apps then wouldn’t able to decrypt the messages.
A software engineer workings in making WhatsApp more secure app said that in today's age piracy is something we should be concerned about. Founder Jan Koum said that “We’ve seen all sorts of people rely on WhatsApp, including political representatives who are using the app to connect with their constituents. We believe that security and privacy of these conversations are highly important,” and “With WhatsApp, we have delivered encryption for everyone. This has become especially important in India as even police are using to stay in touch with citizens, help keep women safe,” he added.
Given Whatsapp huge 1 billion user base, rolling out the end-to-end encryption in the year 2016 is one of the best decision taken by the company. For every new user encryption of their messages is always on by default for their convenience. Every message which is sent on or after June 2016 is encrypted. The only persons having the ability to see messages is, the sender and recipient.
The basis of WhatsApp’s End-to-end encryption is developed by Open Whisper Systems, one of the world's leading software security company. Founder also said that WhatsApp has collaborated over more than 2 years to make the E2E encryption available for their platform. Kao said that “The Signal system has been heavily audited by third-party systems and recommended by the world’s leading security experts. It is also designed to work well from the ground up on mobile. Even the new status feature on WhatsApp is end-to-end encrypted,”
And the only keys used for decrypting of E2E messages were kept secure by using Advanced Encryption Standard (AES) 256-bit encryption deployed by the company.
