Explained in 5 points: WhatsApp chats are end-to-end encrypted, what it means?

Of late, WhatsApp has been talking a lot about privacy. --As per WhatsApp, under the end-to-end encryption policy -- all messages, photos, videos, voice messages, documents, status updates and calls exchanged on the platform are secured and can't be accessed by bad actors. End-to-end encryption ensures chats are secured between the sender and receiver of the message and no one, including WhatsApp can access the conversation at any given point. --WhatsApp says that an end-to-end encryption feature ensures all messages are secured with a lock, and only the recipient and the sender have “the special key needed to unlock and read them.” This simply means that all your chats with all your contacts are unreadible to everyone other than the sender and receiver of the messages. --Recently, there have been a lot many controversies around WhatsApp's end-to-end encryption feature and the Indian government's current IT rules that state, if required, social media platforms such as WhatsApp must have provisions for “identification of the first originator of the information”.
