HTTP & HTTPS
HTTP & HTTPS is one of the protocol of web address (URL)
For example:
http://www.google.com
HTTP: an acronym for Hyper Text Transfer Protocol is a system that is used to transmit and receive information from a server
For example:
http://portal.kmpp.matrik.edu.my
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 used the SSL/TLS protocol for encryption and authentication
For example:
https://www.cimbclicks.com.my
Instead of Hyper Text Transfer Protocol (HTTP), certain website uses Hyper Text Transfer Protocol with Secure socket layer (HTTPS)
By using HTTPS, the computers agree on a "code" so that no one in between can read them
This keeps your information safe from hackers
Differences between HTTP and HTTPS:
HTTP
A system for transmitting and receiving information from a server
Is less secure as the data is vulnerable to hackers
No certificates are required
HTTPS
A system for transmitting and receiving information in a secure format from a server
Is more secure as the data is encrypted before it is sent across a network
Requires SSL Digital Certificate
