                      A secret agent is on a top-secret mission. A partner has sent an encrypted message containing critical
                      instructions. To complete the mission safely, the message must be decoded.
                      To read the message, shift each letter three places backward. Spaces remain unchanged.
                      Decrypt this message to reveal the instructions:

                      How WhatsApp Uses Encryption?

                      When we send a message like “Hi, how are you?” on WhatsApp, it does not travel openly across
                      the Internet. Instead:

                          WhatsApp encrypts the message, turning it into a secret coded form.
                          Even if someone tries to intercept the message, they will only see random letters and numbers.

                          Only friend’s phone has the unique key that can unlock the code and read the actual message.

                      This is why WhatsApp displays the message “Messages are end-to-end encrypted.”
                      It means the chat is protected and can only be read by the sender and the person being messaged.

                              Hello                   Hello                                                Hello

                      TIPS TO PROTECT PERSONAL DATA

                      In today’s digital world, personal data is constantly being collected, stored, and shared across
                      different apps and websites. This information includes details like name, phone number, email,
                      location, and even online activities. If not protected properly, it can be misused for scams, identity
                      theft, financial fraud, or privacy invasion.
