What is the difference between HTTP and HTTPS?

Answer»

The differences between HTTP and HTTPS are:

HTTP
HTTPS
HTTP stands for HyperText TRANSFER Protocol.
HTTPS stands for HyperText Transfer Protocol Secure. It is also known as HTTP over TLS or HTTP over SSL.
HTTP URLS begin with http://
HTTPS URLs begin with https://

WEBSITES running over HTTPS have a redirect in place so that if you type http://, the browser will redirect to deliver over a secured connection.
HTTP uses Transmission Control Protocol (TCP) to transfer data packets over port 80.
HTTPS uses TCP for data transfer as well, but over port 443 and the connection is encrypted by Transport LAYER Security (TLS).
HTTP is less secure. It is vulnerable to hackers.
HTTPS is secure. It is secure against attacks.
HTTP does not scramble the data before transmission.
HTTPS scrambles the data before transmission and de-scrambles the data on receiving.
HTTP is faster.
HTTPS is slower.
A website USING HTTP does not require an SSL certificate.
A website using HTTPS requires an SSL certificate.
