The "S" in HTTPS indicates a secure site. If you visit a web

site or web page, and look at the address in the web browser, it

will likely begin with the following: http://. This means that the

web site is talking to your browser using the regular 'unsecured'

language. In other If you fill out a form on the web site, someone

might see the information you send to that site. This is why you

never ever enter your credit card number in an http web site! But

if the web address begins with https://, your computer is talking

to the web site in a secure code that no one can eavesdrop on.

If a web site ever asks you to enter your credit card

information, you should 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!

Before the important informational contributions of Mr.

Edward Snowden, it was generally believed the above to be

essentially factual. Today however, it

is possible that even TLS/SSL encryption does not guarantee

cryptographic

integrity of messages, unfortunately. In all respects, the

author of the above answer is, we believe, correct.

Unfortunately, there are other ways to intercept and read

date in transit via mechanisms such as the MitM (Man in the Middle)

attack, even without the involvement of the NSA.
