Understanding HTTP/S
HTTP is an acronym for Hyper Text Transfer Protocol, while HTTPS is an acronym for Hyper Text Transfer Protocol Secure which is the secure version of HTTP, the protocol over which data is sent between your browser and the website that you are connected to. The 'S' at the end of HTTPS stands for 'Secure'. It means all communications between your browser and the website are encrypted.
If you visit a Website or web page, and look at the address in
the web browser, it is likely begin with the following: http://.
This means that the website is talking to your browser
using
the regular unsecured language. In other words, it is possible for
someone to "eavesdrop" on your computer's conversation with the
Website. If you fill out a form on the website, someone might see the
information you send to that site.
This is why you should never ever enter your Credit/Debit card
number in an Http website! But if the web address begins with https://, that
means your computer is talking to the website in a Secure code that no one can
eavesdrop on. You understand why this is so important, right?
If a website ever asks you to enter your Credit/Debit card
Information, you should automatically look to see if the web address begins
with https://.
If it doesn't, You should NEVER enter sensitive Information such
as a Credit/Debit card number.
HTTPS is
often used to protect highly confidential online
transactions
like online banking and online shopping order forms.
Web browsers such as Internet Explorer, Firefox and Chrome also
display a padlock icon in the address bar to visually indicate that a HTTPS
connection is in effect.
