What is SSL

SSL Stands for Secure Socket Layer and it was created by the Netscape to make the secure transactions between the browser and the web server.  It is a standardized security technology that establishes a secure link.  To create a secure connection your web server is required to have a secure certificate.  SSL is embedded in all the popular browsers like Mozilla Firefox, Opera and Internet Explorer and it becomes activated when a connection is established with a secure website is SSL enabled. 

 

The web address for the SSL enabled connections start with https i.e. if you are connecting with www.xyz.com and it has enabled SSL then the web address will be like this https://www.xyz.com .  Secure Socket layer does not required any specialized software to work as it is embedded in the web browsers. 

 

When the web browser connects with the secure servers, it automatically asks for the digital certificate.  This digital certificate is the authority that validates the web server’s authenticity and ensures that you are not sending the data insecure and imposter website.  Authenticated Secure Socket Layer certificates have proven to making the secure online transactions.

 

The inner working and the complexities of the secure transactions remains invisible to the people.  While doing online transactions make sure that there is a lock sign on the lower right corner of your web browser.

How SSL Works

  • A web browser generates a request for a secure web page.
  • Web server generates a public key with Certificate and sends it to the web browser.
  • Browse validates the authenticity of the certificate and ensures that is valid certificate and generated by intended website.
  • Browser and server starts sending secure codes to each other.
  • Browser uses the public key to encrypt the URL http data.
  • Web server decrypts the http data and URL by using the private key.
  • Web server sends back the requested document and the data (encrypted with the symmetric key) to browser.
  • Browser decrypts the data and the requested html document by using the symmetric key.

Why SSL is Required?

Secure Socket Layer Certificate consists of public and private key.  Public key is used to encrypt the data and the information and private key is used to decrypt it.  While doing the online transactions the SSL certificate authenticate the web browser and web server.  You need SSL when you have a shopping site, online store and e-commerce website and you are accepting the online orders through credit cards.

You need SSL, when company has multiple offices that are connected and share sensitive data with each other.  You share with your business partner sensitive data through extranet and SSL is the perfect security solution for you.
