An SSL, or Secure Socket Layer, is technology that has been developed that allows web browsers and web servers to communicate over a secured connection.

The system uses cryptography that uses two keys to encrypt data  a public key known to everyone and a private or secret key known only to the recipient of the message. It’s a way to encrypt data, like credit cards numbers (as well other personally identifiable information), which prevents the "bad guys" from stealing your information for malicious intent.

The recently introduced SSL v3 improved upon SSL v2 by adding SHA-1 based ciphers, and support for certificate authentication. SSL v2 was known to be flawed in a variety of ways. Identical cryptographic keys are used for message authentication and encryption. The older version did not have any protection for the handshake, meaning a Man-in-the-middle downgrade attack could go undetected.

SSL has recently been succeeded by Transport Layer Security (TLS), which is based on SSL and is included as part of both the Microsoft and Netscape browsers and most Web server products. SSL uses the public-and-private key encryption system from RSA, which also includes the use of a digital certificate.

SSL-enabled client software can use standard techniques of public-key cryptography to check that a server's certificate and public ID are valid and have been issued by a certificate authority (CA) listed in the client's list of trusted CAs. Client authentication allows a server to confirm a user's identity. It’s a way to assure a client that they are dealing with the real server they intended to connect to. It can prevent any unauthorized clients from connecting to the server, preventing anyone from meddling with data going to or coming from the server.

From the very beginning SSL was designed to provide security between client and server, and to avoid any kind of 3-way man-in-the-middle attack.

Conceptually it’s quite simple: it negotiates the cryptography algorithms and keys between two sides of a communication, and establishes an encrypted tunnel through which other protocols (like HTTP) can be transported. It can also be easily passed through firewalls and proxies, as well as through NAT (Network Address Translation) without issues.

As you know there is lots of information out there on this subject. These days we are blessed being that we have the world of information at our finger tips. This of course can be helpful but it can also be overwhelming.

If you want to generate a real income then you will need to treat your venture with a serious mind set. One that is detailed and specific. I visit a number of forums online and I notice a certain pattern.

Those who succeed seem to be far more detailed in how they succeeded. Those who fail seem to be only detailed in blaming the reasons why they failed. They do not provide specifics as to what they did.

The reason maybe because they would have to defend their actions. They would be exposed and vulnerable to criticism.

By the way this criticism would be constructive because the majority of folks out there would genuinely point out what you are doing wrong and how you can go about fixing it.

You see those who succeed are not afraid of this. They understand that they may have shortcomings and welcome constructive analysis in order to move themselves closer to their objective.

The point I want to make is this. In order to bring anything from the world of ideas into the world of reality you will need to be detailed in your execution.

I mean you could not go to a bank and ask the bank manager for venture capital if all you have is ideas with no basis in reality. You will have to be specific and provide actual actions you can take to achieve your goal.

The same should hold true before you buy into any business opportunity online or build any website. Before you invest anything you need to provide a detailed outline as to what you are prepared to do and how you are going to do it - based upon the reality of your given set of skills and circumstances.

Once you do this I promise you that you will build a real business that will generate a real income because your execution will be detailed and specific and grounded in reality.
