SSL (Secure Sockets Layer) is a standard security protocol for establishing encrypted links between a web server and a browser in online communication.
The usage of Secure Sockets Layer technology ensures that all data transmitted between the web server and browser remains encrypted. An SSL certificate is necessary to create a Secure Sockets Layer 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. A Private Key and a Public Key.
Certificate Signing Request
The next step is the submission of the CSR (Certificate Signing Request). Uniquely, a data file that contains your details as well as your Public Key. The CA (Certification Authority) would then validate your details.
Following successful authentication of all details, you will be issued an 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/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.
Secure Sockets Layer Certificate
A Secure Sockets Layer Certificate comprises 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 an 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.
What are the SSL and TLS Certificates?
SSL or TLS (Transport Layer Security) certificates are data files that bind a cryptographic key to the details of an organization.
When the SSL/TLS certificate is installed on a web server, it enables a secure connection between the web server and the browser that connects to it.
The website’s URL is prefixed with “https” instead of “http” and a padlock is shown on the address bar. If the website uses an extended validation (EV) certificate, then the browser may also show a green address bar.
What are Secure Sockets Layer used for?
The SSL protocol is used by millions of online businesses to protect their customers, ensuring their online transactions remain confidential.
A web page should use encryption when it expects users to submit confidential data, including personal information, passwords, or credit card details.
All web browsers have the ability to interact with secured sites so long as the site’s certificate is issued by a trusted CA.
Why do I need a Secure Sockets Layer certificate?
The internet has spawned new global business opportunities for enterprises conducting online commerce.
However, that growth has also attracted fraudsters and cybercriminals who are ready to exploit any opportunity to steal consumer bank account numbers and card details.
Any moderately skilled hacker can easily intercept and read the traffic unless the connection between a client (e.g. internet browser) and a web server is encrypted.
Secure Online Transactions and Communication
All communications sent over regular HTTP connections are in ‘plain text’ and can be read by any hacker that manages to break into the connection between your browser and the website. This presents a clear danger if the ‘communication’ is on an order form and includes your credit card details or social security number.
With an HTTPS connection, all communications are securely encrypted. This means that even if somebody managed to break into the connection, they would not be able to decrypt any of the data which passes between you and the website.
How Does the Secure Sockets Layer Work?
The following explains how SSL Certificate works on a website.
The process of how an ‘SSL handshake‘ takes place is explained below. In regards to the Instant SSL by the Comodo Certificate Authority:

When the browser confirms that the website can be trusted, it creates a symmetric session key. This encrypts with the public key in the website’s certificate. The session key is then sent to the webserver.
Then again, the web server uses its private key to decrypt the symmetric session key. And in addition, the server sends back an acknowledgment that is encrypted with the session key. From now on, all data transmitted between the server and the browser is encrypted and secure.

Implementing your Website Secure Sockets Layer
Implementing SSL for a website is quite easy! A typical installation of an SSL certificate involves the following steps:
Step 1. Acquire your Secure Sockets Layer Certificate
To implement SSL/TLS security on your website, you need to get and install a certificate from a trusted CA.
A trusted CA will have its root certificates embedded in all major root store programs like internet browsers. As well as the mobile devices used by your site visitors. You should also decide which type of certificate suits you best.
Some examples of the main SSL Certificates by Comodo include;
Because of this, EV certificates contain a unique differentiator designed to clearly communicate the trustworthiness of the website to its visitors.
Step 2. Activate and install your Secure Sockets Layer certificate
A web host takes care of the SSL certificate activation upon purchase. The administrator of the website can also activate the SSL through Web Host Manager (WHM) or cPanel.
In the WHM dashboard select the SSL/TLS option and choose “Generate SSL Certificate and Signing Request“.
Next, generate your Private Key and fill out the form for Certificate Signing Request (CSR). Ensure that you enter your domain name in the box asking for “Host to make cert for“.
You will need to send this CSR to your CA in order to purchase a certificate. For help on how to generate a CSR using various webserver types, see more details in this article.
Comodo SSL Certificate Installation Guide
Comodo offers detailed guides for installing certificates on various web servers too. See SSL Certificate Installation on Different Web Servers for a full list.
The guides provide installation instructions for different software types such as Apache, Apache on Cobalt, BEA, C2Net Stronghold, Ensim, F5, Hsphere, IBM, Microsoft, Netscape / Sun, Novell, Plesk, SSL Accelerator, Website Pro, and Zeus.
Step 3. Update Website from HTTP to HTTPS
HyperText Transfer Protocol Secure (HTTPS) is the secure version of HTTP. The ‘S’ at the end of HTTPS stands for ‘Secure’. It means all communications between your browser and the website are encrypted.
More often, HTTPS is used to protect highly confidential online transactions. Like online banking and online shopping order forms. HTTPS pages typically use one of two secure protocols to encrypt communications – SSL (Secure Sockets Layer) or TLS (Transport Layer Security).
The Secure Sockets Layer connections Signature
Web browsers such as Internet Explorer, Firefox, and Chrome also display a padlock icon in the address bar. To visually indicate that an HTTPS connection is in effect. As such, you must now configure your website too.
So that your site visitors are automatically directed to the “HTTPS” version. In addition, search engine providers like Google are now offering SEO benefits to SSL pages. So the effort to serve all pages on your site over HTTPS is well worth it.
Who issues the Secure Sockets Layer Certificates?
A certificate authority or certification authority (CA) issues SSL certificates. On receiving an application, the CA verifies two factors:
It confirms the legal identity of the enterprise/company seeking the certificate and whether the applicant controls the domain mentioned in the certificate.
The issued SSL certificates are chained to a ‘trusted root‘ certificate owned by the CA. Internet browsers such as Firefox, Chrome, Internet Explorer, Microsoft Edge, etc. have these root certificates embedded in their ‘certificate store‘.
Only if a website certificate chains to root in its certificate store will the browser allow a trusted and secure https connection. If a website certificate does not chain to root then the browser will display a warning that the connection is not trusted.
Details included in the Secure Sockets Layer certificate
Secure Sockets Layer Certificates contain the following details;
- the domain name or common name
- serial number
- details of the issuer
- period of validity
- issue date and expiry date
- SHA Fingerprints
- a subject public key algorithm
- the subject’s public key
- certificate signature algorithm
- certificate signature value
Additionally, the organization validated and extended validation certificates also contain verified identity information about the owner of the website. Including, organization name, address, city, state, and country.
How can you tell when a site uses a Secure Sockets Layer?
A web page using SSL will display
- “https://” instead of “http://” before the website’s address in the browser’s address bar
- A padlock icon in the address bar of the browser before the address.
- With an Extended Validation Certificate, the address bar also shows the registered name of the company. Particularly that which owns the website, the name of the issuing CA and, an additional green security indicator.
In general, it is clear to note that your website presence is very important. However, without acquiring the trust of your online visitors and blog traffic, all your efforts would be futile.
Especially, if your website does not provide your web customers with a verification padlock. Not to mention that most customers earn your full trust through safeguarding and protecting their online presence at all costs.
By the same token, your website visitors can verify you are a registered business and that you own the domain. As can be seen, customers are more likely to trust and complete purchases from a website that uses HTTPS.
