WhatsApp is used daily by over 1 billion people and among users are celebrities who share private data, businessmen who give bank accounts etc., and the developers have to make sure that their messages won’t be read by hackers who will use information to blackmail users and steal their money. Facebook has introduced end-to-end encryption to boost the apps’s privacy, but this technology has been also adopted by other rival messaging apps such as Telegram, G Data’s Secure Chat, Criptyque’s Pryvate and many more.
Encryption has been introduced on WhatsApp since the launch of this application, but in the meantime, the developers have adopted superior end-to-end encryption, relying on from Open Whisper Systems’ perfect forward secrecy (PFS), which involves private keys being stored on users’ devices and which are changed for every message. This technology is very secure and it protects message even from WhatsApp’s employees, as only the sender and recipient have access to what’s inside them.
So, if you still have doubts about the security of WhatsApp, there are other free applications that offer similar features. Pryvate from Criptyque, a fully encrypted communications platform that can be installed on mobile devices and which offers two services: Pryvate and Pryvate Pro (a free 30-day free trial). The former has features that include unlimited voice calls, instant messenger and receiving conference and video calls. The latter has all the features mentioned above, as well as the option to initiate video and conference calls, it offers customer service, email functionalities and anti-blocking enabling communication, which is done through firewalls.
Recently, the application has introduced Presence capabilities and it informs users if their recipients take a screenshot of their message. Soon, a self-destruct instant messaging feature will be added, as well.
