Know More About Secure Sockets Layer (SSL)

Secure Sockets Layer (SSL) is the most widely used technology for providing a secure communication between the web client and the web server.Most of us are familiar with many sites such as Gmail, Yahoo etc. using https protocol in their login pages.When we see this, we may wonder what’s the difference between http and https.In simple words HTTP protocol is used for standard communication between the Web server and the client. HTTPS is used for a SECURE communication.
What exactly is Secure Communication ?

Suppose there exists two communication parties A (client) and B (server).

Working of HTTP

When A sends a message to B, the message is sent as a plain text in an unencrypted manner.This is acceptable in normal situations where the messages exchanged are not confidential.But imagine a situation where A sends a PASSWORD to B.In this case, the password is also sent as a plain text.This has a serious security problem because, if an intruder (hacker) can gain unauthorised access to the ongoing communication between A and B , he can see the PASSWORDS since they remain unencrypted.

Now lets see the working of HTTPS

When A sends a PASSWORD (say “mypass“) to B, the message is sent in an encrypted format.The encrypted message is decrypted on B’s side.So even if the Hacker gains an unauthorised access to the ongoing communication between A and B he gets only the encrypted password (”xz54p6kd“) and not the original password.This is shown below


How is HTTPS implemented ?

HTTPS is implemented using Secure Sockets Layer (SSL).A website can implement HTTPS by purchasing an SSL Certificate.Secure Sockets Layer (SSL) technology protects a Web site and makes it easy for the Web site visitors to trust it. It has the following uses

1. An SSL Certificate enables encryption of sensitive information during online transactions.
2. Each SSL Certificate contains unique, authenticated information about the certificate owner.
3. A Certificate Authority verifies the identity of the certificate owner when it is issued.


How Encryption Works ?

Each SSL Certificate consists of a Public key and a Private key. The public key is used to encrypt the information and the private key is used to decrypt it.When your browser connects to a secure domain, the server sends a Public key to the browser to perform the encryption.The public key is made available to every one but the private key(used for decryption) is kept secret.So during a secure communication, the browser encrypts the message using the public key and sends it to the server.The message is decrypted on the server side using the Private key(Secret key).

How to identify a Secure Connection ?

In Internet Explorer, you will see a lock icon Picture of the Lock icon in the Security Status bar. The Security Status bar is located on the right side of the Address bar.You can click the lock to view the identity of the website.

In high-security browsers, the authenticated organization name is prominently displayed and the address bar turns GREEN when an Extended Validation SSL Certificate is detected. If the information does not match or the certificate has expired, the browser displays an error message or warning and the status bar may turn RED.

So the bottom line is, whenever you perform an online transaction such as Credit card payment, Bank login or Email login always ensure that you have a secure communication.A secure communication is a must in these situations.

Starting a Blog

by Peter Barnes


The multitude of steps required to successfully start a blog can become a little complex, especially if you are determined on making it your #1 source of income. This article should be considered a brief tutorial as opposed to a whole walkthrough. If you're just starting out, taking notes on this article is a great place to get grounded in the fundamentals.
Your first step will be to discover a theme, something in which you already have knowledge of or wouldn't mind writing about, while taking search engine popularity into consideration.

The second step when beginning a blog is to pick out a blogging service. There are many good services available. Two of these are TypePad.com and Xanga.com. Most of these make it easy for you to add revenue-growing ads, such as Google Adsense.

Third, you should determine the appearance of your blog. From the colors to the number of columns, those individuals who want to pull in a decent income from their blogs have to make sure that the blog's appearance is decent.

Those interested in starting a blog should also consider investing in an offline blogging client. These allow you to type your blog entries in a word processing format, similar to MS Word. This makes it less difficult for you to publish blog entries.

Another great idea is to add 'bells and whistles' to your blog to make it more magnetic to visitors, and those who are frequent readers. Bloglet, for example, permits readers to sign up to your site and receive an email whenever you make a new post.

You should also publicize your blog through blog tracking sites such as Pingomatic. Another good idea is to submit your best posts to Blog Carnivals. High quality posts on many topics are collected at these types of sites.

Adding content on a regular basis is the only way that your blog will get acknowledged. If done right, it'll create a great source of income for you down the line.
