The end-to-end encryption of WhatsApp came to the application in August 2016. Before this system was included, the security on the platform was poor and even in 2011 it was discovered that conversations could be leaked.
This change makes it easier to use.
His intention with end-to-end encryption was to change this problem. With this system, messages, photographs, videos and audios are encrypted when they are sent and are only decrypted when they reach the recipient’s device.
According to WhatsApp, through this system they offer security and privacy to their users and that everything they send is safe and does not fall ” into the wrong hands .”
But how do they make this possible?
To implement this encryption system, the company collaborated with Open Whisper Systems, a company known for working on products such as Redphone, Signal or TextSecure. According to those responsible for Open Whisper Systems, to create the WhatsApp system they were based on the one that TextSecure had at that time.
This end-to-end encryption was and continues to be possible thanks to keys that are stored on each user’s device . These keys are unique and, according to them, not even the WhatsApp staff can access the information encrypted under this system.
” WhatsApp has no way of listening to calls or seeing the content of messages that are encrypted from end to end – ensures the company – This is because the encryption and decryption of messages sent and received through WhatsApp occurs completely on your device ”.
