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...

Microsoft Office for Tablet now on Google Play store

Back in November, Microsoft opened up early previews builds for its new mobile Office applications for Android tablets to those willing to sign up and wait for an invitation. After taking on feedback over the past couple of months, Microsoft has announced that it is expanding its preview scheme by releasing its Office applications to everyone directly through the Google Play Store. The new Office software for mobile unifies Android, IOS, and Windows platforms. Previously each platform had to make do with its own apps, meaning that feature sets differed depending on your operating system and updates were often slow and intermittent. By unifying the Office platform, Microsoft hopes to bring updates and new features to users in a timelier manner. There are still a couple of conditions attached to the preview builds though. Firstly, Office is still limited to ARM-based Android tablets with a screen size between 7 and 10.1 inches. Your tablet will also need to be running Ki...
