Complete Explanation of SSL Functions
Have you ever thought that if you enter various personal data to register on a website, the data can be stolen by people? If the website uses technology in the form of SSL, you can still breathe easy because the various personal data you enter on the website are guaranteed to be securely encrypted and can minimize data theft.
The question now is what SSL actually is and what is the function of SSL? Why is it possible to secure personal data on a website as secure as that? How does it work? In this article we will discuss what SSL is and also various other explanations related to SSL as well.

Understanding SSL

First of all, you must first know what SSL really means and why you should use SSL on a website that is indeed required to enter personal data to register as a user or other matters related to entering personal data on a website. 

What is SSL

SSL stands for Secure Sockets Layer and, in a nutshell, it is the standard technology for keeping internet connections secure and protecting any sensitive data sent between two systems, preventing criminals from reading and altering any information transferred, including potential personal details. The two systems can be server and client (for example, shopping websites and browsers) or server to server (for example, applications with personally identifiable information or with payroll information).
It does this by ensuring that any data transferred between the user and the site, or between two systems remains impossible to read. It uses encryption algorithms to scramble data in transit, preventing hackers from reading it as it is sent over the connection. This information can be anything sensitive or personal which can include credit card numbers and other financial information, names and addresses.

Why Need to Use SSL

Companies and organizations need to add SSL certificates to their websites to secure online transactions and maintain the confidentiality and security of customer information.
In short: SSL keeps internet connections secure and prevents criminals from reading or changing information transferred between two systems.
There are various reasons why it is necessary to use SSL, including:

Avoid Data Theft

The main thing is to avoid data theft from irresponsible parties. With the SSL security system, the data on a website, whether it is already stored or on its way to the web server is well encrypted and also avoids data theft on a website.

Avoid Sending Wrong Data

Misrepresenting data is a very big danger for website owners. This can happen because during the data transmission process, the information contained in the data passes through various machines, and this can increase the potential for fake webs to accommodate that information. With SSL, this will provide authentication by which information can be sent to the correct address.

Increase Website Reputation

Did you know that implementing SSL on your website will affect the reputation of the website? You should know that Google legally announced on August 6, 2014 that HTTPS-only encryption is available with SSL certificates. This will be a positive thing for search engine rankings and SEO.

Increase Website Ranking in Search Engines

As mentioned above, SSL greatly affects SEO (Search Engine Optimization). This is related to the Google search engine which is more concerned with websites that implement SSL because it is considered a good and safe website.

How SSL Works

SSL works by ensuring that any data transferred between a user and a website, or between two systems, remains impossible to read. It uses encryption algorithms to scramble data in transit, which prevents hackers from reading it as it is sent over the connection. This data includes potentially sensitive information such as name, address, credit card number or other financial details.
The process works like this:
  1. The browser or server tries to connect to a website (that is, a web server) that is secured with SSL.
  2. The browser or server requests that the web server identify itself.
  3. The web server sends a copy of its SSL certificate to the browser or server in response.
  4. The browser or server checks to see if it trusts the SSL certificate. If it does, it signals this to the web server.
  5. The web server then returns a digitally signed acknowledgment to initiate an SSL-encrypted session.
  6. The encrypted data is shared between the browser or server and the web server.
  7. This process is sometimes referred to as an “SSL handshake”. While it sounds like a lengthy process, it happens in milliseconds.
When a website is secured with an SSL certificate, the HTTPS (HyperText Transfer Protocol Secure) acronym appears in the URL. Without the SSL certificate, only the HTTP letters – that is, no S for Secure will appear. The lock icon will also be displayed in the URL address bar. It signifies trust and gives reassurance to you visiting the website.

SSL Function

When SSL was first launched, it became a breath of fresh air for all companies or individuals who manage their websites because it offers extra security. SSL functions include:

SSL Function Encrypts Sensitive Information

Of course the main reason for using SSL is about security issues. By using SSL sensitive information or even all information will be encrypted and scrambled so that it cannot be read except with the destination page.

SSL Function Provides Authentication

Apart from encryption, SSL also provides authentication. This authentication makes the information sent will arrive at its destination safely. Without an irresponsible third party who steals data that contains such important information.

SSL Types

For information, there are various types of SSL that are very commonly used on various websites, including:

Domain Validated SSL (DV SSL)

This requires businesses to prove their control over the domain name only. The certificate contains the domain name that was provided to the issuing authority as part of the request. Since organizational identity is not checked here, Domain Validation certificates are the most basic level of SSL certification, and are only suitable for test servers and internal links.

Organization Validated SSL (OV SSL)

This requires applicants to not only prove that they own the domain name they want secure, but also prove that their company is registered and legally responsible as a business. The certificate issued then becomes proof of the domain and company name. This level of authentication is suitable for public-facing websites that collect personal data from site users. Note that individuals cannot obtain these certificates, only organizations and businesses.

Extended Validated SSL (EV SSL)

Extended Validation SSL helps protect users from providing their details to fake websites that can be used by criminals for phishing. EV SSL requires both of the above validations for the domain and company as well as some additional related verification steps to prove that the company’s SSL certificate is registered.
This additional company information is then represented in a certificate issued in the address bar and can be accessed from many web browsers by clicking on the lock icon. When visiting a site with EV SSL, many browsers show a green address bar as a highly visual sign of trust in websites and businesses to handle personal information. This type of certificate is also available for organizations and businesses only.

SSL Certificate

An SSL certificate is a digital certificate that authenticates the identity of a website and allows an encrypted connection. SSL stands for Secure Sockets Layer, a security protocol that establishes an encrypted link between a web server and a web browser.
