What is the Difference Between HTTP and HTTPS?

The HyperText Transfer Protocol, or HTTP, has been around since the beginning of webpages. However, HTTPS, which offers more security for websites and visitors, was established in 1994. Since then, the significance of moving from HTTP to HTTPS has been discussed. Initially, this question was crucial for particular business sectors (like payment services), but it is now relevant for many websites. This results from the more stringent network security standards, which we will discuss today. In this post, we also demonstrate how to switch from HTTP to HTTPS, complete with all the subtle procedural details.

How do HTTP and HTTPS work?

A web resource and a server can exchange data via the HTTP protocol across the Internet. With its assistance, user queries are communicated to the server (through a browser), and the server then produces responses, which it then sends back to the browser. These are the fundamental guidelines for data transport.

The same protocol, HTTPS (Hypertext Transfer Protocol Secure), has a significant addition. There is an addition to HTTPS called SSL (Secure Sockets Layer). This certificate ensures the security of data transmission across the network.

How to Do HTTP and HTTPS Functions?

Unencrypted data communication offered by HTTP increases the risk of information interception by a third party. For instance, billing information entered on an HTTP website could be captured by hackers while it is transferred to the server.

Why does HTTPS exist? With the help of this protocol, you can send data in an encrypted format to protect against data reading.

What function does HTTPS serve?

The following are the primary reasons to use HTTPS:
  • The user's personal information is protected by an HTTPS connection, enhancing his network security. This safeguard encourages trust and has a favorable effect on client loyalty.
  • The EU General Data Protection Regulation went into effect in May 2018. It controls how user data is gathered and processed within the European Union. The security and integrity of user data submitted to a website is one of the fundamental tenets of the regulation. As a result, websites that offer services to EU nationals must adhere to higher security standards. Websites must employ a secure data connection in particular.
  • The HTTPS protocol has started to influence Google's ranking since 2014. Today, most websites listed in Google's TOP-5 for most searches employ an HTTPS certificate.
  • Beginning in July 2018, the Chrome browser indicates in the address bar that a website is unsafe if it lacks an SSL.

This security safeguard stops users from giving such websites their personal information. Learn more about ways to verify the security of a website's connection.

For HTTP webpages, a few technical aspects are yet to be available. For instance, websites with SSL certificates are the only ones that can use web push technology.

Thus, attempts to switch from an unsecured connection to a protected one will reduce the risk of personal data theft, enhance SEO indications, safeguard against legal violations, benefit product presentations, and increase technological capabilities.

The Benefits and Drawbacks of HTTPS HTTPS advantages:

  • It enhances the safety of websites. The enhanced protocol offers essential protection against data theft owing to encrypted transmissions, but it only offers complete protection against threats and hacker attacks.
  • Increased likelihood of a search engine promotion being successful. Every year, this preference Google for websites with secure connections becomes more pronounced. There is no justification for losing competitiveness.
  • Data protection for mobile devices. Because of the sharp rise in the use of mobile devices for internet access, this factor is significant in the modern world.
  • Customers feel more secure using a website with high levels of security. More than 80% of consumers, according to polls (the GlobalSign research), will only make purchases on secure websites.
  • We have access to modern technology. Earlier, we covered push notifications. Websites that use HTTPS are the only ones that support geolocation and Progressive Web Apps (PWA) technology.

Downsides of HTTPS

  • The acquisition of an SSL certificate is necessary for a secure connection. Organizations can choose from various certificate levels based on their requirements and position.
  • The encrypted information impacts website speed because servers need more processing time.
  • The HTTPS protocol is often used when creating new websites. However, the HTTP protocol is utilized by numerous websites. Although switching from HTTP to HTTPS can be time-consuming, many businesses have found the switch worthwhile in the long run.

How do I change to HTTPS?

Several preparations need to be made before converting to HTTPS. A change in the website address (URL) indicates a transition. As a result, internal link addresses on the website must be changed from absolute (such as http://site.com/articles) to relative (such as /site.com/articles). You can get an SSL certificate if your website's content (internal links, images) can be accessed and displayed correctly.

Selecting an SSL certificate

Two factors influence the selection of a certificate:
  • what information did you gather (only names and emails or billing details)
  • what services you offer (a bank, an online store, or a blog with a subscription form).
  • Data must be encrypted when communicating between a web server and a web browser. An SSL certificate is a file that includes the cryptographic key needed for this. This key is linked to the company that purchased the certificate. 

Certificate Type SSL

Five different types of SSL certificates exist:
  1. DV, or Domain Validated 
  2. OV, or Organization Validated 
  3. EV, Extended Validated
  4. Wildcard
  5. Multi-Domain
EV, Extended Validated Wildcard, Organization Validated, Domain ValidatedThe most straightforward certificate is Multi-Domain DV. It requires domain ownership to be verified; no other documentation is required. It is appropriate for websites without a payment feature. This certificate is adequate if users can merely submit their name and email address on the website. 

E-commerce websites frequently employ the OV SSL certificate. Having legitimate verification documents is a requirement for obtaining an OV SSL certificate for a business or an individual. The Certificate Authority will verify their identity, website ownership, physical address, and phone number. After that, a Seal Of Trust and a certificate will be given. Users feel more secure after they are added to the website.

Financial institutions and well-known businesses frequently use EV SSL. These certificates represent the highest level of confidence and need further verification from businesses. These browsers stopped displaying the green line in the address bar for websites with EV certificates starting with Chrome V77 and Firefox V70. However, by clicking on the lock icon before the URL, any visitor can verify the organization's name and the type of certificate.

It is preferable to obtain a Wildcard certificate if a website has numerous subdomains. It safeguards all top-level subdomains, such as blog.domain.com and mail.domain.com. You can get a Multi-Domain SSL certificate to secure several domains. Generally speaking, it is less expensive than getting a certificate for each domain.

You can view the strategies of the business SSL.com, which sells all varieties of certificates:

Who offers SSL? What distinguishes the various businesses?

After confirming an organization, Certificate Authorities (CA) issue certificates. The following are the primary variations across certificate authorities:

The SSL's cost, supported browsers, and CA's reliability in terms of customer care
A warning will appear while accessing a website if the browser being used does not support the CA that is being used. IdenTrust, DigiCert, and Sectigo are the three most often used authorities. 

Do free certificates exist?

There are free certificates, but they have limitations. 
Some browsers fail to recognize these certificates and notify website visitors of the problem with an error message. 
Free certificates must be renewed more frequently than paid certificates and may cost money. 
Some free SSL certificates are not suitable for use in commerce. 
Try out a free certificate offered by the well-known nonprofit Let's Encrypt. They immediately generate DV certificates for them, initially valid for 90 days.

How is a certificate installed on a website?
You must first purchase a certificate. Depending on the type of certificate, different conditions apply to the issue. For instance, to obtain a DV certificate, you must:

Create a CSR (Certificate Signing Request), which you must send to a CA to apply for a certificate.
Pass a domain ownership verification.
You must undergo a corporate check to obtain an OV or EV certificate: You should submit the CA proof of your ownership of the website and company.

You must go through the installation process after verification. Your host server determines the method.

You need: to install the certificate.

The RSA private key. The key is created after sending the certificate file and associated root certificates in response to a CSR request.
If your host has unique features for installing certificates, it is worthwhile to inquire with their support team. A few hosting providers charge extra for the installation of SSL certificates. The steps above can be skipped and will still be completed for you.

How can you ensure that your website functions properly now that it is HTTPS?
Because it doesn't affect traffic, installing a certificate on a new website is more manageable than on an existing one. If you plan for the change, you can avoid losing visitors if the website is actively marketed in search engines. 

You need to update website settings before preparing to migrate to the new protocol:
  • Reroute HTTP URLs to HTTPS
  • update the website's listing in Google Search Console and select a geographic target
  • Website owners are responsible for safeguarding user data. There are several benefits to switching from HTTP to HTTPS, both in terms of security and business marketing. Your website will rank highly on Google and be able to employ the newest technologies (web push notifications, PWA) if it uses the HTTPS protocol.
