A Web-certificate functions as follows:
Whenever anybody transacts with a "secure" web-site, their browser (or server) authenticates the identity of the web-site using the web-certificate
If the site's certificate is not valid, a warning is issued to the user, otherwise the web-cert creates an SSL (Secure Server Layer) session and encrypts any information exchanged during that session
This prevents communication from being intercepted and deciphered by nefarious people on the Internet.
Can you explain "how a web certificate works" in "Plain English"?
Basically, when two parties (say a customer and the Amazon.com web-site) wish to "talk" securely (transfer the customer's credit-card number to Amazon.com), then a web-certificate sets up a "secure" session that first verifies the true identity of the party that requests data transfer (Amazon.com).
If a certificate is valid, the other party (the customer) gets a message saying that its OK to "talk" to them (Amazon.com), as they are who they say they are. The other party (customer) then transfers the info (CC number) securely, without fear of any nefarious elements intercepting the data.
If the certificate is invalid, a message pops up saying so. Transactions can still occur, but at the risk of counter party fraud (It may be joesbooks.com tying to appear as Amazon.com)
How can someone tell whether a website is using a web certificate or not?
The pages of a web-site which are secured by a web-certificate are characterized by the following traits:
The URL of the secure web-pages change from »
... to »
A lock symbol appears in the lower left-hand (right hand) status bar in Netscape Navigator (Internet Explorer).
If one wants to view and verify the encryption information of the secure pages, onw should simply undertake the following:
In Netscape - click on the lock symbol above and select "View Certificate" button
In Internet Explorer - double-click on the lock in the lower right-hand status bar.
