SSL (secured socket layer) explained

Secured Socket Layer

This technology was developed by Netscape in the Mid 1990s. The technology has become standard in exchanging data over unsecured environment like the internet.

Since we already mentioned that SSL secured data exchange on an unsecured environment like internet, and we all know that internet is almost all about websites. SSL helps in securing your website data. Once this service is installed on your server, a padlock sign will always appear on your address. Which will change HTTP (hypertext transfer protocol) to HTTPS (Hypertext transfer protocol secured). As already mentioned this technology has become standard to almost all websites. Once this certificate is installed on your server your data is secured (don't forget that a perfect system doesn't exist but at least the attacker has to put effort to get through).

SSL uses a handshake like techniques to make sure data is secured. When client needs to access data from a saver or location that uses SSL, the server will provide digital certificate to the client. This credentials will make the user identify the server. The client make sure the domain name matches the with the CA (certificate authority this is a body that issues digital certificates. Digital certificate certifies the ownership of the public key by the named subject of the certificate). The client has to make sure the name on the certificate corresponds with the domain name (web address) and the certificate is valid.

After completion of the handshake, the client will encrypt the data and send it over the server. This is done before the data leaves the client system (smart devices or computer). As we all knew that encrypted data cant read or tempered with, unless if it comes under heavy attack. At arriving at the server end, the server has to decrypt the data to use it. If the server needs to send by data to the client, the data has to be encrypted too.

Internet without this technology will have been an untrusted place! SSL make the internet a bit secured though not fully secured!

Powerful words from Steve Jobs on his sick bed

Powerful message. Steve Jobs’ Last Words - I reached the pinnacle of success in the business world. In others’ eyes, my life is an epitome of success. However, aside from work, I have little joy. In the end, wealth is only a fact of life that I am accustomed to. At this moment, lying on the sick bed and recalling my whole life, I realize that all the recognition and wealth that I took so much pride in, have paled and become meaningless in the face of impending death. In the darkness, I look at the green lights from the life supporting machines and hear the humming mechanical sounds, I can feel the breath of god of death drawing closer… Now I know, when we have accumulated sufficient wealth to last our lifetime, we should pursue other matters that are unrelated to wealth… Should be something that is more important: Perhaps relationships, perhaps art, perhaps a dream from younger days ... Non-stop pursuing of wealth will only turn a person into a twisted being, just l...

Turn your Word doc into a PDF with a live table of contents

A long report needs to be broken up into sections. Readers will want shortcuts to the chapters that most interest them. So, if you’re distributing your reports as PDFs, you’ll want live tables of contents in which readers can easily go to the chapters they want to read. Fortunately, this is easy to do in Word 2010 or 2013 (I haven’t tested this in earlier versions). First of all, you need to set up your document properly. Use Word’s outline styles— Heading 1, Heading 2 , and so on—to organize your report. For instance, you might want to assign large section titles as Heading 1, chapter titles as Heading 2, sub-chapters as Heading 3, and so on. By the way, using these headings has other advantages. You can select View>Outline and work on your document as a collapsible outline. Also, the left tab of the Navigation pane uses these styles. But back to the table of contents. When you’re ready to distribute your document, select the References tab and click...
