Many of you may be aware of this difference, but it is worth sharing for any that are not conversant with it.
The main difference between http:// and https:// is all about keeping you secure
HTTP stands for Hyper Text Transfer Protocol The S (big surprise) stands for "Secure".. 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 never ever enter your credit 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.
PASS IT ON (You may save someone a lot of grief as well as spare them from paying the price of ignorance)!
