HTTPS
A secure transfer system that encrypts the data before the connection is formed for sending or retrieving the data from the server (also known as HTTP with secure socket layer SSL)
HTTPS is a secure version of the HTTP protocol that uses the SSL/TLS protocol for encryption and aunthentication
for example:
https://www.cimbclicks.com.my
Instead of Hyper Text Transfer Protocol(HTTP), certain websites uses Hyper Text Transfer Protocol with Secure socket layer (HTTPS)
By using HTTPS, the computers agree on a 'code' between them, and then they scramble the messages using that 'code' so that no one in between can read them
this keeps your information safe from hacker
