Difference between http and https

I just want to share to you this message that I received from Ned. I did not know the difference as well and I believe that this information is really helpful especially now that we are using the web for a lot of reasons. Here it goes:

FIRST, MANY PEOPLE ARE UNAWARE OF: **The main difference between http and https.

It's all about keeping you secure.

**HTTP stands for HyperText Transport Protocol, which is just a fancy way of saying it's a protocol (a language, in a manner of speaking) for information to be passed back and forth between web servers and clients.The important thing is the letter S which makes the difference betweenHTTP and HTTPS. The S (big surprise) stands for "Secure".

If you visit a website or webpage, and look at the address in the web browser, it will likely begin with the following: http://. This means that the website is talking to your browser using the regular'unsecure' language. In other words, it is possible for someone to "eavesdrop" on yourcomputer'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 basically 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 card information, you should automatically look to see if the web address begins with
https . If it doesn't, there's no way you're going to enter sensitive information like a credit card number.

It better to be careful than to be sorry for things that we dont know.
