Web browsers and web servers count on the SSL or Secure Socket Layer protocol for helping users prevent their data at the time of transferring. It does so by introducing an encrypted channel for personalized communications over the internet. Usually, the SSL certificate comprises a key pair and verified identification information.
Whenever a client or web browser points towards a confidential site, the server ensures sharing the public key with the client for establishing an encryption procedure and an exceptional session key. The client usually confirms that it identifies and relies the SSL certificate issuer. This procedure is also referred to as the SSL handshake and it initiates a secure session which prevents message privacy, server security and message integrity.
With the help of strong encryption, at 128 bits you can calculate as much as 288 time more combinations as you would have done with the help of a 40 bit encryption. Now, with such a combination we can rightly say that this is almost trillion times influential.
At present computing speeds, any hacker with the tools, time as well as motivation will need to enforce trillion times more efforts than before to break a particular session. In fact, for a secured session you need to opt for SGC enabled certificate. For enabling strong encryption for majority of website visitors, ensure selecting a SSL certificate which allows 128 bit minimum encryption for 99.9% of site visitors.
Just as your passport or driving license is the proof of your identity, in the like manner, SSL certificates are defined as your credentials for establishing an identity in the online world. No sooner than a browser starts connecting to the server, you will find that the server will send the identification details to the browser.
