What is SSL certificates and how does it affect the website

Blog 25
SSL is the Internet's "citizen identity card," which means you can be sure you're sending data to the right server and not to an impostor.

1. What is an SSL certificate?

SSL (Secure Sockets Layer) is a standard of security technology that encrypts data between a user's browser and a web server via the HTTPS protocol. This certificate ensures that the files transferred between the browser and the server are private and secured. SSL is currently being applied as the security standard for millions of websites, prevent data from being stolen.

2. How many types of SSL out there?

SSL is provided by the Certificate Authority (CA), which is the organization that issues digital certificates to users, play a role as a third party (trusted by others) to support the information exchange process.

The number of CAs today is extremely large, making it difficult to list the number of SSL varieties offered. But the most popular SSLs and provided by all CAs can be divided into 3 groups:

  • Domain Validation SSL (DV SSL): for customers with standard encryption capabilities, DV SSL only requires verification of domain ownership. The registration process is quick, so it is preferred by small businesses.
  • Organization Validation SSL (OV SSL): for organizations and businesses with high reliability. In addition, it is also necessary to verify that the registrar exists and is functioning properly. The business name will also be displayed in detail OV SSL certificate.
  • Exented Validation SSL (EV SSL): has the highest reliability, needs to go through multi-step verifications. The latest browser versions now require this level of security.

3. How SSL works

SSL encrypts sensitive information when sent over the Internet. When enabled, the information becomes unreadable to everyone except the server we sent data to. As a result, hackers cannot steal information.

Data is transmitted over the Internet, will have to get through a lot of servers and web servers to reach the destination. SSL establishes a "handshake" connection to ensure files are secured, which involves several steps. For example, if you want to visit the website: https://chips.vn/en to refer the services of Chips, then:

  • Step 1: You send an access request from the browser, the browser will “ask” Chips website: “I brought a lot of money and personal information to buy your service, is it safe here, Chips?”
  • Step 2: Chips will respond: “We have SSL certificate for security, international standards, please feel free to test it!”
  • Step 3: “Alright Chips, then I will upload the certificate to the authentication server (CA), see if it is approved. Oh! I see. Chips registered, this SSL is valid, so we can start transfering data from now."
  • Step 4: Chips sends a key used to encrypt and decrypt data, from now on you and Chips can freely exchange. The key will change each time in the next transaction, another person will not be able to decrypt it even with they accidently (or intentionally) catched the data.

4. What we get if using SSL

Data security: data is encrypted and only the true recipient can decrypt it, so it will not be read or stolen by hackers. So does secure webmail, applications such as Outlook Web Access, Exchange; secure FTP, intranet data transfer services, File Sharing; secure VPN Access Serves, Citrix Access Gateway,...

Provides Authenticity: SSL is the Internet's "dentity card," which means you can be sure you're sending information to the right server and not to an impostor who trying to steal your information. And on the other hand, the data sent by the SSL holder can certainly be traced back and cannot be denied.

Visitors trust: Web browsers will give users signals to know that their connection is secure, which can be a lock icon or a green bar. As a result, customers will trust the website more, improve its reputation, increase the chance to buy, or gain loyalty to the website.

SEO benefits: HTTPS integrated in SSL certificate is Google's website ranking criterion (95% of websites on Google use HTTPS). It means that when giving results to searchers, a website with an SSL will have priority over a site of the same type but without this certificate.
