SSL Certificate (Secure Sockets Layer) is a standard security protocol for establishing encrypted links between a web server and a browser in an online communication.
SSL certificate creates the sign of the secure of your any transaction. Now a days its usage of SSL technology ensures that all data transmitted between the web server and browser remains encrypted as well as secure.
There are also an SSL certificate is more necessary to create the SSL connection. You would need to give all details about the identity of your website and your company as and when you choose to activate SSL on your web server. Following this, two cryptographic keys are created:
- Private Key.
- Public Key.
By the process, in the next step it needs to submit the CSR (Certificate Signing Request), which is a data file that contains your details as well as your Public Key.
The CA (Certification Authority) would then validate your all details. Following successful authentication of all details, you will be issued SSL certificate. The newly issued SSL would be matched to your Private Key.
From this point onwards, an encrypted link is established by your web server between your website and the customer’s web browser.
On the apparent level, the presence of an SSL protocol and an encrypted session is indicated by the presence of the lock icon in the address bar. A click on the lock icon displays to a user or customer details about your SSL. It’s to be remembered that SSL certificates are issued to either companies or legally accountable individuals only after proper authentication.
An SSL certificate comprises of your domain name, the name of your company and other things like your address, your city, your state and your country. It would also show the expiration date of the SSL plus details of the issuing CA. Whenever a browser initiates a connection with a SSL secured website, it will first retrieve the site’s SSL certificate to check if it’s still valid.
It’s also verified that the CA is one that the browser trusts, and also that the certificate is being used by the website for which it has been issued. If any of these checks fail, a warning will be displayed to the user, indicating that the website is not secured by a valid SSL certificate.
