When customers enter their information such as email addresses, passwords or credit card details, these data travel through several network or servers before it reaches its intended destination. When the connection is not encrypted, hackers seize this opportunity to act upon their fraudulent activities by snooping on the connection.

How does an SSL Certificate Work

When someone visits an SSL-powered site, the visitor’s web browser and the website’s servers must virtually ‘shake hands’ to initiate a session. This is how it goes:

  1. The web browser starts by requesting the certificate.
  2. As soon as it receives and confirms this, it produces a code known as the master key, then encrypts the connection using the public key connected to the certificate.
  3. Then, it forwards the encrypted master key back to the website’s server.
  4. Since the web server has the private key under the public key, it has the ability to decrypt the master key. The latter is used to authenticate the message that is sent back to the visitor.
  5. The virtual ‘handshake’ has been completed and the two parties can now engage in a secure session.


What does a Certificate Authority (CA) do?

A Certificate Authority or CA is a trusted organisation that issues digital certificates that verifies a client’s online identity. Digital certificates like SSL plays an integral part in the public key infrastructure (PKI).

You can tell who issued the digital certificate by simply clicking on the padlock symbol on the address bar on top beside the website’s URL.

A security certificate works on both private and public keys. It is used to maintain a secure connection between the visitor’s browser and the site’s servers. It certifies that the signed public key linked to that website belongs to the website’s owner.

Using its own private key, the Certificate Authority signs the public key, hence, the credibility of a CA adds more impact to the reliability of the private keys they certify.


5 Different Types of SSL Certificates

To know what SSL certificate is right for your site, here are five different types of SSL certificate you should take note of.

  1. Domain Validated Certificates (DV)

Domain Validated Certificates (DV)

DVs provide an industry standard encryption with less paperwork compared to other types of SSLs. This is ideal when validating and securing low-volume websites, personal blogs and Facebook apps.

it can be issued in a few minutes since the CA only needs to validate that you are the owner of the domain you want to secure. Due to its simplicity, DV certificates are among the most affordable security certificates you can find.   

Below is an example of a Domain Validated Certificate. Notice that on the address bar, there’s a green padlock followed with ‘https’ right before the website address: This means that your connection with this website is secure and private.

  1. Organization Validation Certificates (OV)

Organization Validation certificates are issued to companies or organisation recognised by the government’s business registry as a legitimate business. The activation process is not that long and normally takes 1-3 business days to complete.

OV certificates have a number of trust indicators but you won’t see the green address bar.  This helps provide security and privacy for customers but may not have the budget for an Extended Validation Certificates (EV). This is especially useful for e-commerce sites that process high-value online transactions.

  1. Extended Validation (EV) Certificates

When it comes to encrypting data, EV certificates sets the security a bar higher. Aside from the industry grade 2048-bit encryption, On the address bar, Extended Validation certificates shows the full company name and the green padlock bar–a veritable sign of trust and authenticity for websites.

It takes a couple of days to weeks to issue this certificate due to the–you guessed it–extended validation process done by the CA. The validation involves verifying the domain ownership and documentation about the company’s legal existence. Companies like Amazon, PayPal and Etsy are just a few high-traffic sites that use Extended Validation certificates.

  1. Multi-domain Certificate

For those who need to secure multiple domains, you can do so with a multi-domain certificate. It is a hassle-free way to secure domains because you don’t need to activate separate SSL certificates for each domain.

You can secure up to 100 domains depending on what the certificate entails. The best thing about multi-domain certificate is that it is convenient to manage several domains with a single certificate.

  1. Wildcard Certificates

A Wildcard Certificate allows one to secure unlimited number of first-level subdomains from a single domain name with a single certificate. As an example, if ‘’ is the main domain, then ‘’, ‘’ and other subdomain variations can be covered by a single wildcard certificate.
