Are messages sent through WhatsApp secure?
The latest version of WhatsApp has been updated to support end-to-end encryption for all messages and data sent on the platform.
What this means is that only you and the recipient ever sees the content of your communications. Not even WhatsApp has visibility. Only the sender and recipient have the unique encryption key to view data and messages.
You’re able to verify that messages are encrypted by tapping the name of the contact or group to open the info screen.
WhatsApp uses a delivery and read receipt system. Whenever you send a message you’ll see a number of tick marks next to your message.
Once you understand this, you can begin the paranoia as to why the recipient is taking so long to reply to your message having read it.
Many friendships and relationships have been tested by WhatsApp’s infamous blue ticks.
In a group chat scenario, you will only see two grey ticks when your message has been delivered to everyone in the group . Similarly, everyone in the group will need to have read it for you to see two blue ticks.
