These are the new WhatsApp features
The first of the new WhatsApp features is that media can now be processed faster. This way, media such as photos or videos can now be changed directly into WhatsApp . An editing app is therefore no longer necessary.

Alleseuropa reports that on November 18, 2014, Open Whisper Systems announced a partnership with WhatsApp to provide end-to-end encryption by incorporating the encryption protocol used in Signal into each WhatsApp client platform.

Open Whisper Systems said that they had already incorporated the protocol into the latest WhatsApp client for Android, and that support for other clients, group/media messages, and key verification would be coming soon after.

WhatsApp confirmed the partnership to reporters, but there was no announcement or documentation about the encryption feature on the official website, and further requests for comment were declined.

In April 2015, German magazine Heise Security used ARP spoofing to confirm that the protocol had been implemented for Android-to-Android messages, and that WhatsApp messages from or to iPhones running iOS were still not end-to-end encrypted. They expressed the concern that regular WhatsApp users still could not tell the difference between end-to-end encrypted messages and regular messages.


On April 5, 2016, WhatsApp and Open Whisper Systems announced that they had finished adding end-to-end encryption to “every form of communication” on WhatsApp, and that users could now verify each other’s keys. Users were also given the option to enable a trust on first use mechanism in order to be notified if a correspondent’s key changes.

According to a white paper that was released along with the announcement, WhatsApp messages are encrypted with the Signal Protocol.[149] WhatsApp calls are encrypted with SRTP, and all client-server communications are “layered within a separate encrypted channel”.[149] The Signal Protocol library used by WhatsApp is open-source and published under the GPLv3 license.

WhatsApp uses a customized version of the open standard Extensible Messaging and Presence Protocol (XMPP). Upon installation, it creates a user account using one’s phone number as the username (Jabber ID: [phone number]@s.whatsapp.net).

WhatsApp software automatically compares all the phone numbers from the device’s address book with its central database of WhatsApp users to automatically add contacts to the user’s WhatsApp contact list.

Previously the Android and Nokia Series 40 versions used an MD5-hashed, reversed-version of the phone’s IMEI as password, while the iOS version used the phone’s Wi-Fi MAC address instead of IMEI.

A 2012 update now generates a random password on the server side. while some Dual SIM devices may not be compatible with WhatsApp, though there are some workarounds for this.

In February 2015, WhatsApp introduced a voice calling feature; this helped WhatsApp to attract a completely different segment of the user population. WhatsApp’s voice codec is Opus, which uses the modified discrete cosine transform (MDCT) and linear predictive coding (LPC) audio compression algorithms. WhatsApp uses Opus at 8–16 kHz sampling rates.

On November 14, 2016, Whatsapp added a video calling feature for users across Android, iPhone, and Windows Phone devices.


On November 2017, Whatsapp released a new feature that would let its users delete messages sent by mistake within a time frame of 7 minutes.

Multimedia messages are sent by uploading the image, audio or video to be sent to an HTTP server and then sending a link to the content along with its Base64 encoded thumbnail (if applicable).

WhatsApp follows a “store and forward” mechanism for exchanging messages between two users. When a user sends a message, it first travels to the WhatsApp server where it is stored.

Then the server repeatedly requests the receiver acknowledge receipt of the message. As soon as the message is acknowledged, the server drops the message; it is no longer available in the database of the server.

The WhatsApp server keeps the message only for 30 days in its database when it is not delivered (when the receiver is not active on WhatsApp for 30 days).

WhatsApp competes with a number of messaging services. Those, as of 2019, were services like iMessage (estimated 1.3 billion active users), WeChat (1 billion active users , Viber (260 million active users), Telegram (200 million users) and LINE (187 million active users). Telegram in particular was reported to get registration spikes during WhatsApp outages and controversies.

WhatsApp has increasingly drawn its innovation from others such as a Telegram-inspired web version and features for groups. In 2016, WhatsApp was accused of copying features from a then-unreleased version of iMessage.
