What is an SSL Certificate? Know the Pricing & 6 Main Types of SSL Certificate

What is an SSL Certificate?

SSL is known as Secure Socket Layer. Which is used in almost all modern websites for Encryption purposes to safeguard user data.it is commonly denoted as HTTPS where S stands for SSL. SSL Secure Sockets Layer (SSL) is a protocol developed by Netscape
Communications Corporation and was invented by Taher Elgamal who was chief scientist at Netscape Communications Corporation.

SSL Certificate is a type of Security certificate issued by an authorized Certificate Authority that verifies the identity of the webserver, it is like a message which is scrambled while transmission so that other message intruders like hackers cannot
view the information. SSL ensures transmitted data stays private between client and
server. This protocol enables the client to authenticate the identity of the server, SSL is an industry-standard protocol that is used by several websites for protecting their online transaction credentials with their customers. in simple words, SSL Certificate is a
method of securing data transaction which happens between a client’s Web Browser and Server. It is handled only by the server-side to protect important information of the user who is using the website on a secure browser, Important information such as username, password, and payment credentials are kept in a scrambled form so that it is not visible to anyone and it is tightly protected. It is commonly denoted as https://example.com and
non-SSL certificates are in HTTP format.

What is an SSL Certificate?

Why SSL certificate?

SSL certificate is proof that the publisher of the website uses top-notch security to protect user data and ensure the user that the website is secure to surf and his/her data is very safe with the website. SSL certificate plays an important role in building trust between a user and the website organization. For this assurance purpose, an SSL certificate is invented. it is like a doctor hanging his degree in his clinic that he is qualified to treat his patients. For example, Bill is a Customer of a trading platform called upstox. Bill is accessing his trading account on the upstox platform using upstox trading website now whenever he tries to buy or sell his stocks his sensitive credentials like bank account or debit/credit card details are exposed on the upstox website which can be infiltrated by a
hacker to protect this data an SSL certificate is required.

Why SSL Certificate?

How much does an SSL certificate cost?

SSL is priced as per the usage purpose of the website organization. SSL cost is controlled annually by an organization called Certification Authority it can be used for free for a year
when a user purchases the hosting plan and is also sold on a subscription basis usually renewed.

There are different types of SSL Certificates they are as Follows;

  • Single Domain SSL Certificate

This SSL certificate protects only one domain and subdomain in its
hierarchy. For example, if one manages multiple domains such as
example.com, blog.example.com, and app.example.com, only one of
these can be protected.

This type of certificate can be purchased for $5 per year.

  • Multiple-Domain SSL Certificate

This certificate can protect any of your different domains and
subdomains. For example, you can purchase coverage for
one.example.com, two.example.com, and sample.com — all through
the same SSL certificate.

This SSL certificate is priced from $60 per year.

  • Wildcard SSL Certificate

This SSL certificate protects a domain and all other first-level
subdomains. For example, you can protect not just sample.com, but also
blog.example.com, app.example.com, and other subdomains.

This SSL certificate is priced from $30 per year.

  • Domain validation (DV)

This is fast and direct validation in which the only thing verified is
your ownership of the domain name. 
This is suitable for website owners who do not require any personal
details from visitors and is usually issued within minutes.

A DV certificate is priced at around $70 per year.

  • Organization validation (OV)

After the certificate authority has checked your domain ownership as
well as basic details of the organization. the OV SSL certificate is
issued. Such as its name and location. An OVL SSL certificate
provides a greater level of assurance than domain validation.

Price of an OV certificate is around $150 per year.

  • Extended Validation (EV)

These certificates are issued after checking the physical and legal
existence of the organization, in addition to DV and OV. 
It is the most laborious level of validation, and hence carries the
highest degree of trust and credibility and cost.

The cost of an EV is $200 per year.

How does SSL certificate validation work?

  1. When a user starts to browse the website of his interest the Web browser attempts to connect to a website secured with SSL. The request from the browser is sent to the webserver to identify itself.
  2. If the authentication process is validated successfully then the server sends the browser a copy of its SSL Certificate.
  3. The browser checks whether to trust the SSL certificate.  If the result is positive than the message is sent to the server.
  4. Then the server sends an electronically signed acknowledgment to start an SSL encrypted session.
  5. Encoded data is shared between the web browser and the server.

What will happen if the SSL certificate expires?

An SSL certificate needs to be renewed between 30 to 60 days before expiration. Because the updating of the SSL certificate on the server takes time. When the SSL you are using gets expired your data can get compromised and there is the chance of sensitive data leaking for both the website and the user which affects the authentication process.
As a result, both your website and users are vulnerable to attacks and viruses. For example, a hacker may take advantage of a website with an expired SSL certificate and create a fake website identical to it.

How does an SSL certificate work between client and server?

Here let us assume the webserver belongs to yahoo.
Step 1: When a Browser requests secure pages(HTTPS) from a yahoo web server
Step 2: The Server Sends its Public key with its SSL certificate which is digitally signed by a third party certificate, Which we may call
Certificate Authority or simply CA.

SSL certificate work between client and server.

Step 3: Once our browser gets the certificate, it will check to make sure the certificate is valid as we know a digital signature is created by a CA’s Private Key and our browser either chrome or firefox is previously installed with many major CA’s public keys. Thus digital signature can be verified once the certificate of signature is verified by the digital certificate and can be trusted. Then a green little padlock icon appears in the address bar. The green padlock simply indicates that the web server’s public key belongs to the webserver, not someone else verification is done. 
step 4: Now its time to exchange a secret that is our browser creates one symmetric key or a shared secret it keeps one and gives a copy to the web server, However, my browser does not want to send the shared secret in plain text. Henceforth, it uses the web server’s public key to encrypt the data, and then sends it to the webserver.
Step 5: when the webserver gets the encoded symmetric key, it uses its private key to decrypt it. Then web server gets the browser’s shared key. From now on all the traffic between the client and the webserver will be encrypted and decrypted with the same key. That is the asymmetric key.

Benefits of SSL

  1. The browser can block the client if the SSL certificate is expired or it is not present. The website gives a warning message as “Your connection is not private”, Which will alert the web user to leave the website.
  2. Increased trust With Visitors, When a user visits the site with an SSL certified batch i.e HTTPS he feels secure and he can carry out sensitive transactions which build trust between the visitor and the web-server.
  3. SEO benefits, from 2014 google announced that Websites with SSL certificates are ranked higher in the search results giving the web-server boost in visits and further increasing their profits.
  4. Increased Security, with websites having HTTPS being termed safe for accepting any payments.  SSL certificates protect against spamming the information between
    user and server by keeping information encrypted. So even if hackers intercept the network they will see a scrambled message which is in encrypted form.


To Conclude modern websites must require SSL certificates to carry out their day-to-day tasks efficiently on a secured network. Hence SSL is very much needed for both client and web-Server for effective transmission of data, trust, and safeguarding against malicious

If you are looking for a Shared Hosting with Free SSL then I would recommend using VCCLHosting which provides servers with NVMe/SSD Storage, Free SSL, and More Features.

Best 9 tips to optimize/improve page speed using inbuilt features of server

Improve Page Speed

Page speed basically means how fast a page loads. It isn’t measured based on on-site load. These two things are very different. Site speed is how fast the page opens on the web while page speed is how fast the contents of the page load. Page load speed affects the interest of the customer on your website. In this blog, we are going to see best ways to improve page speed using features available in our server. A study shows that if the page speed is less than 1 second then the bounce rate (customer leaving the website) is 7% reduction in yearly revenue. You can imagine it with the example of Amazon. 1-sec delay can cost Amazon 1.6billion sale reduction. So the faster the page load speed, the more the customer is happy and that reflects in more the conversion rate. And it ultimately reflects in revenue.

Nowadays Google has started to make a ranking list based on the page load speed. Which site has more page load speed appears at the top. The below image shows the research results of bounce rates.

improve page speed

So, if the page load speed is more then the customer conversion will be less. So it is inversely proportional to each other.

How page load speed is measured

Google has defined three metrics as Core Web Vitals as page speed measurements.
1) LCP(Largest Contentful Paint )- It measures loading performance
2) FID(First Input Delay)- Measures interactivity
3) CLS(Cumulative Layout Shift)- Measures visual page stability

Now it becomes very vital to understand how can we increase the page speed as it directly affects the business revenue. Below are some methods you can use for the user experience.

How to improve page speed

To improve page speed you need to work on various factors, below we are suggesting some methods to improve page speed of your website which is already existing in your server.

1. Use a better host for your website

Below are the three possible hosting types- There are three possible types of hosting:

i) Shared hosting: Shared hosting is the cheapest way and less time consuming to implement and have a good page speed. You share CPU, RAM, Disk space with other websites. It’s definitely cost-effective but it’s not as fast as VPS or dedicated servers. It’s mainly because sharing the server can get overloaded and it strains your page loading time. It’s suitable for small businesses.

ii) Virtual Private Servers (VPS hosting): It comes with a dedicated RAM, virtual CPU which only you have access to. It gives you a specific set of assets so that you have full control of them. It provides great speed.

iii) Dedicated server: It’s the most expensive way. In this case, you own your own physical server. It’s faster than VPS. Another solution will be to rent dedicated cloud resources from Microsoft Azure or AWS. Here you will be getting a dedicated server so only you will have access and full control of it. It can be called a “Hybrid Cloud” option. It also gives you benefits such as flexibility, security, high performance and total control.

2) Use a CDN (Content Delivery Network):

When a user experiences a delay in page loading, it is mainly due to the physical distance between the end-user and the host. The more the distance, the more the delay. CDN is a network built with multiple cache servers at a different location, known as Points Of Presence (POPs). This helps to reduce the distance and gives a better User experience.

improve page speed

There are other solutions for page speed which does not include server choice. Let’s discuss more them below

3) Reduce Redirections:

Too many redirects can make the page load slower. Sometimes redirects are necessary when you are moving from one domain to another. But if unnecessary redirects are avoided or the Top-Level domain is resolved to max one then it increases the page speed significantly.

4) Keep the images in optimized data size:

We all know how images play a significant role in website user experience. Especially for e-commerce websites. But having large size images may slow down the webpage experience. So instead of reducing the number of images and image quality, you can just reduce the image size.

5) Enable Website caching:

If there are a lot of users accessing the page at the same time, the servers work slowly. It needs more time to load the web page to each user. Caching enables the storing of your current version of the website and presenting it until it’s updated. This means that the web page doesn’t render repeatedly for each user. Due to this website doesn’t need to create requests each time for databases.

6) Minify JavaScript and CSS files:

If your website uses more javascript then it leads a user to identify as an individual HTTP request. Which ultimately slows down your page loading time. So try to group the CSS files and Javascript into one so that it will reduce the HTTP requests and will increase your page speed.

Some other important effective ways to improve pagespeed

1) Compressing Images

Images are most common contents on webpage for download. Compressing images helps to save bytes of disk and improve the performance. To find optimal image format and compressing strategy many analysis aspects need to be observe like, encoded data, format of image, quality and image resolution. GIF and PNG are most common and popular formats in compression activity. For motionless image PNG gives best compression format and quality. For video and animated pictures GIF format is suitable.

2) Cache Expire Policy

Webpage loading time is influenced by activity to save and use files repeatedly. Whenever user revisit the cache helps to reduce loading time. Browser caching technique helps to properly download CSS, HTML and JavaScript code. If  you see Cache Expire header is crashed,

You can fix through wordpress by adding cache control and headers. Use follwing code with Nginx and add in configuration file of server.

If you use Apache Server use following coding in .htaccess file.

< filesMatch “.(ico|pdf|flv|jpg|jpeg|png|gif|svg|js|css|swf)$”>
Header set Cache-Control “max-age=75600, public”

Here cache will expire after 75600 sec.

Add Expire Session in Nginx in Server block

location ~* .(jpg|jpeg|gif|png|svg)$ {
expires 90d;
location ~* .(pdf|css|html|js|swf)$ {
expires 3d;

Add Expire Session in Nginx in Server block

location ~* .(jpg|jpeg|gif|png|svg)$ {
expires 90d;
location ~* .(pdf|css|html|js|swf)$ {
expires 3d;

Add Expire in .htaccess file of Apache (Add it in header section)

ExpiresActive On ExpiresByType image/jpg “access 6 months” ExpiresByType image/jpeg “access 6 months ” ExpiresByType image/gif “access 6 months ” ExpiresByType image/png “access 6 months ” ExpiresByType image/svg “access 3 months ” ExpiresByType text/css “access 2 months ” ExpiresByType application/pdf “access 2 month” ExpiresByType application/javascript “access 2 month” ExpiresByType application/x-javascript “access 2 month” ExpiresByType application/x-shockwave-flash “access 2 month” ExpiresByType image/x-icon “access 7 months ” ExpiresDefault “access 5 days”

3. Adding AMP or mobile friendly pages

 Accelerated Mobile Pages (AMP) is an open source technique to increase website speed on mobile. AMP pages are lightweight to accelerate SEO impact. Billions of AMP pages are working and running with high performance and engagement. It gives flexible result in webpage speed, search ranking and interne marketing.


Now we know that how much page load speed can affect the business. So it becomes very important to improve the loading speed. The most important factor the improve the page speed is server configuration. Another factor impact is not that crucial. So it’s very important to take the server configuration into account. The more the space, dedicated access, and other assets the more the page speed is. Keep the below points in mind while applying the effective solution

Conversion- customer conversion rate

Usability- How responsive is your website to a customer request

Visibility – How fast it loads

These three factors play important role in website ranking.

Difference between Web Server and Application Server

Web server and Application server are two terms that are used in the same context but still have their own differences, understanding these differences may help you to use these technologies in your favor. In this post, we will see the main difference between Web Server and Application Server with examples.

What is a Web server ?


Before knowing the differences between Web Server and Application Server, lets know about the definitions and use of both servers.

Difference between Web Server and Application Server

A web page is a collection of raw material ranging from images to text files to database context. End users sitting out on a computer somewhere on the internet a web server is a piece of software that runs on the same computer. When you ask for the web page the web server put all those raw material together into a web page and then sent it back out over the internet to your web browser.

Common examples of web server software are Apache and NGINX. Web servers are all about dealing with the HTTP content or content which can be handled over the HTTP protocol. . In a web server system, it stores, process, es and deploys web pages to customer. A customer is either a web browser or a device app. A web server can serve content like pictures, videos, text, and font size.



1. Microsoft IIS-


It is an Internet Information Service platform for web servers, which gives packages for windows-based servers. It specially used to manage to host content on the web page. It also gives GUI to manage websites and user accounts.

2. Eclipse Jetty


Eclipse Jetty delivers web server and container packages and supports HTTP/2 and other integrations like JMX, OSGi, WbSocket, and many more. This software are open source and available free for enterprise use. Jetty is embeddable and asynchronous with cloud computing platforms like Google AppEngine and SaaS like Yahoo. The latest version of Jetty is Jetty 11.0.x, Servlet 5.0 and Java 11+.

What is Application server ?



Application Server Working
Working Process of Application Server

Application servers are specifically designed to run applications by the combination of both hardware and software.  It provides an environment for programs to run. An application server is a server that allows both the creation of web applications and running a business logic that is needed to build and run dynamic content, transaction results, decision support, or real-time analytics. So basically an application server provides the business logic for clients. The application server has its own dynamic features and can be used to create and run dynamic modules. It is a software platform that deploys applications including mobile apps, web, and browser-based applications.

The successful business logic can be implemented using application servers. This business logic causes dynamic changes in data and enables the productivity of applications like transactional activity, decision support app, and real-time scenario analysis. Client-Server communication is the foundation of the Application Server and it includes transaction process, secure network, and concurrency control.

Difference between Web server and Application server ?



Let’s understand the difference between the web server and application server by examples, suppose I have a file ‘script.js’ this file contains a javascript programme, which can be executed and a result can be generated. Now suppose I served this file to my client through a web server, the client will receive only the contents of the file, the javascript won’t be executed.  

But in case of a application server, client  want to serve the ‘script.js ‘ file and wish to execute that file using programming environment.  A Web Server will send the HTML as output for all requests sent to the server.  It does not have any backend logic. So that is the fundamental difference between the a web server and an application server. 

While an application server can do the task which a web server can do too, but webserver can’t do the tasks of an application server.  Yes, there are some plug-ins for a web server that can help a web server to act as an application server to some extent but the efficiency and functionality of an application server can’t be achieved by a web server.

Examples of Application Server:


These examples will help you to understand the difference between Web server and Application server

1. Nginx



It is a web server with open source technology, with load balancing and proxy for mail capacity. As per the study of Netcraft, Nginx can provide service and manages the load of 38% of global websites and 25% engaged sites till December 2019. Nginx used by multiple well-known companies like Netflix, Zynga, and Dropbox.

2. Glassfish



It is a famous open-source application server served on the JAVA platform and developed by Sun Microsystems. The extension of it is now managed by Eclipse Foundation. Glassfish platform reinforces JavaBeans,  Servlets, and many more.

3. WebLogic


It is Oracle’s product of application server to deploy apps in distributed manner using JAVA EE technology. It is fully meshed with Oracle’s platform and cloud services.

3. Apache Tomcat Server



Apache Server is a globally used open-source technology of web-based server runs on Java Servlets. It is used to render and deploy web pages with JAVA code and Java EE (Java Enterprise Edition). Its high-availability Java application server for servlets, JSPs, and WebSockets.

Difference between Web Server and Application Server



Application Server Web Server
Able to deploy dynamic data. Able to deploy static data.
Multiple protocols used like HTTP to develop business logic. Only HTTP protocol is used for communication.
Able to serve websites and business applications Only support website based applications.
Multithreading technology is used to serve multiple clients requests. Do not serve multithreading.
Smoothly running complex processes with resource management. Good for less resource management in web traffic.
Application Database is use to perform connection with backend. Static database is use to connect with backend.
