What is HTTPS?


HTTPS stands for Hypertext Transfer Protocol Secure. It is a secure HTTP extension or version. The main use of this protocol is to protect data transfers between a website and a web browser. The internet is frequently used for private communications. This protocol transmits data using the 443-port number. This protocol is also known as HTTP over SSL. Because the HTTPS channels are secured using the SSL (Secure Socket Layer). Many web browsers by default recognize HTTPS.

Websites that ask for login information should use the HTTPS protocol to transmit data.

What exactly is HTTPS?

HTTP is the standard protocol for data transmission between a web browser and a website, and HTTPS is its secure variant. HTTPS is encrypted to increase the security of data transfer. When users register for a bank account, email address, or health insurance provider and send sensitive data, this is essential.

Due to the HTTPS protocol; users of websites may securely transmit sensitive data like credit card numbers, financial information, and login credentials over the internet. As a result, HTTPS is essential for securing online activities including remote work, banking, and shopping. However, HTTPS is progressively replacing HTTP as the default protocol for all websites; Regardless of whether they send sensitive data or not.

What sets HTTPS apart from HTTP?

HTTPS adds encryption, authentication, and integrity to the HTTP protocol:

  • Encryption:

Because it was designed, to begin being a clear text protocol, HTTP is vulnerable to man-in-the-middle and eavesdropping attacks. Using SSL/TLS encryption, HTTPS protects against data being intercepted. It can be accessed by a third-party while being transported over the internet. Through public-key cryptography and the SSL/TLS handshake; it is possible to establish a secure encrypted communication session between two parties that have never met (for instance, a web server and browser). This is done by creating a shared secret key.

  • Authentication:

HTTPS, as opposed to HTTP, uses the SSL/TLS protocol for secure communication. An SSL/TLS certificate for a website contains a public key. That key a web browser can use to confirm that files transferred by the server (such as HTML pages); have been validated by a person in possession of the corresponding private key. If the server’s certificate has been signed by a publicly recognized certificate authority (CA), such as SSL.com. The browser will understand that any identifying information provided in the certificate has been validated by a trustworthy third party.

Additionally, HTTPS websites can be configured for verification. In that case, the web browser shows the user’s client certificate. Mutual authentication helps to reduce the danger of cyber scams and other attacks involving credential theft in situations. Here multi-factor authentication is desirable, such as remote employment.

  • Integrity:

Each file (such as a web page, image, or JavaScript file) is transferred to a browser by an HTTPS web server. It includes a digital signature that a web browser may use to confirm; that the file hasn’t been altered in any way while in transit. To verify the authenticity of the page, the browser can independently create a cryptographic hash of the document’s contents. It can be computed by the server, together with its digital certificate.

For web browsing and online transactions, HTTPS is a significantly more secure protocol than HTTP. HTTPS guarantees of encryption, authentication, and integrity are taken into account.

What information does HTTPS give users about website owners?

Three basic validation methods are used by CAS when issuing digital certificates. The validation method employed affects the data that will be included in an SSL/TLS certificate for a website:

    • Only the owner of the domain name protected by the certificate is confirmed by Domain Validation (DV). It is a service provided by the organization that sought the certificate.
  • In Organization / Individual Validation (OV/IV) certificates, the validated name of a business, another organization (OV), or a single person (IV) is included (IV).
  • Extended Validation (EV) certificates, which stand for the highest level of internet trust, involve the most work from the CA. Only companies and other registered organizations are given EV certificates. It contains the organization’s recognized name, not the individual.

By default, Privacy, and Integrity

Since private connections are now utilized by default, there are new expectations that make everyone safer.

By always using HTTPS, web services can avoid having to make a judgment call about what is “sensitive.” As a result, deployment is simpler, more dependable, and less prone to error. Due to HTTPS’s widespread adoption, clients can start to assume it with greater trust. Attacks designed to track a large volume of unencrypted traffic are no longer desirable.

Web browsers have the potential to start presenting HTTP connections as insecure and HTTPS connections as normal. There may be stricter penalties for HTTPS validation errors, which would decrease the impact of user error and fraud. These updated standards set higher standards for HTTPS security across all websites. In other words, fewer sensitive sites are empowered to be safeguarded by safeguarding fewer sensitive ones.

HTTPS is the next stage of the internet

  • There is an agreement among the online community of practice, web browsers, major tech companies, and internet standards bodies. It is that HTTPS should be the default for all web traffic.
  • The Technical Architecture Group of the W3C believes that HTTPS will eventually displace all other online connections.
  • The parent organization of the IETF, the Internet Architecture Board, recommends that encryption be used by default in all future protocols. Widespread tracking, according to the IETF, constitutes an attack.
  • Chrome and Firefox’s security teams are working to eventually classify plain HTTP as unsafe.

The ultimate goal of the internet community is to standardize encryption and phase out unsecured connections. Because HTTPS is quicker, cheaper, and easier to use, everyone wins. Significant institutions and technology companies have committed to moving websites and services. They are improving the current situation and giving back their advancements to the general public. It has led to numerous improvements over the previous few years.

Just why use HTTPS?

Advantages of HTTPS

Using HTTPS on your website and insisting on HTTPS; when using other people’s computers or devices to surf the internet or conduct business has various benefits:

  • Integrity and Authenticity

Through encryption and authentication, HTTPS ensures the integrity of communications between a website and a user’s browsers. Your users will be able to have confidence in authenticity. Nothing sent from your web application has been intercepted or altered by a third party while it is in transit. If you decide to spend extra money on EV or OV certificates; they will also be able to ascertain that the information genuinely came from your business or organization.

  • Security

Of course, the biggest advantage of HTTPS is greater security. You can provide your website with an encrypted SSL/TLS connection by switching from HTTP to HTTPS. This suggests that data and information are no longer sent in plain text. For eCommerce sites that manage credit card data, this is a requirement. Although it is not a statutory requirement. Still, it is your responsibility as a company to protect the information of your clients.

This also applies to WordPress blogs and login pages. This data is provided in plain text to the server each time a user registers on a multi-author WordPress website. It uses HTTP. HTTPS is necessary to maintain a secure website and browser link. You can better protect against hackers accessing your website by doing this.

  • Compatibility

Recent browser innovations are pushing HTTP’s incompatibility closer and closer. Google Chrome is increasingly integrating mixed content blocking. Mozilla Firefox recently introduced an optional HTTPS-only mode (HTTP resources linked to HTTPS pages). When HTTP is paired with browser notifications of “insecurity” for HTTP websites, it is clear that HTTP is gone.

  • User experience

Due to recent changes to the browser user interface, HTTP sites are now flagged as unsafe. When users visit your website, do you want their browsers to notify them: it is “Not Secure” or show a lock that has been crossed out? Of course not!

  • SEO

Search engines, such as Google, employ HTTPS as a score indicator for producing search results. Therefore, website owners can easily boost their SEO. It is by configuring their network services to use HTTPS rather than HTTP.

  • Confirmation

The data validation step is carried out by handshaking in HTTPS. Every data transfer that takes place is authenticated. It includes those involving its parts like the sender and receiver. Only after the validations are successful can data transfer occur. If not, the actions are terminated.

  • Consistency

The green lock that appears on the URL assures users that a website is security-conscious. Customers who trust a website are more likely to be ready to make a buy.

Disadvantages of HTTPS

  • Cost

Switching to HTTPS necessitates the purchase of an SSL certificate. Although the SSL certificates are issued by the website hosting operator in large numbers. They must be renewed annually by paying an annual fee. There are other ways to get a free SSL certificate. However, doing so is not recommended due to security concerns.

  • Performance

Data encryption and decryption over HTTPS connections do require a lot of computation. As a result of the slow response time, the website’s speed is reduced.

  • Syncing

For some materials, storing them in HTTPS will result in problems. Past public storage won’t take place again. As a result, ISPs won’t be allowed to store encrypted content. Sites with a lot of traffic typically experience this problem. However, greater bandwidth avoids these issues from happening.

  • Accessibility

Some firewall and proxy setups restrict users from visiting HTTPS websites. This can happen as a result of both intentional and unintended behavior. The administrators may have forgotten to put up HTTPS access if it wasn’t done on purpose. Sometimes, this is done on purpose as a safety measure.

  • Calculating Costs

The task of encrypting and decrypting data requires more computer resources from both the server and the browser. These overheads are often not noticeable because of the added delay that connection setup causes. If your HTTPS connections manage multiple HTTPS connections at once, though, this could become a problem.

  • Different Content

Your site will start downloading files via HTTP rather than HTTPS if the setting is off. As a result, users will gradually be informed about insecure content.

What role does HTTPS play?

HTTPS adds encryption to the HTTP protocol by encapsulating HTTP in the SSL/TLS protocol (this is why SSL is referred regarded as a tunneling protocol). All communications between two networked computers are therefore encrypted in both directions (e.g., a client and web server). Although eavesdropping may still be able to read IP addresses, port numbers, domain names, the amount of data transmitted, and the duration of a session; all of the actual data delivered is safely encrypted by SSL/TLS.

  • Website content
  • Headers
  • Cookies
  • Request URL


HTTPS also uses the SSL/TLS protocol for authentication. SSL/TLS uses digital records known as X.509 certificates to link cryptographic key pairs with the identities of entities. It includes websites, persons, and businesses. Each key pair consists of a private key that is kept private and a public key that can be shared publicly. Anyone can use the public key to:

  • Send an email that only the private key holder can decrypt.
  • Use the right private key to validate a message’s digital signature.

Conversion Instructions for HTTP to HTTPS

Switching your WordPress site from HTTP to HTTPS is now the fun part. Let’s first go through a few qualifications and some crucial details.

  • There will be a need for an SSL certificate. We’ll go into further detail on this below.
  • Check once more to make sure your CDN provider and WordPress host both support HTTP/2.  You should have this for performance even though it is not required.
  • You should set aside a lot of time to transition from HTTP to HTTPS.
  • It takes more than five minutes to complete a migration.
  • Ensure that all of the third-party scripts and services you use have an HTTPS version.
  • You must be aware that all of your pages and posts will lose their social share counts. It is if you don’t use a plugin that enables share recovery. This is because you have no control over independent social networks and an API. It analyses the HTTP version to determine your share statistics.
  • Depending on the size of your site; it can take Google some time to re-crawl all of your new HTTPS pages and articles. You can see variations in traffic or rankings at this time.
  • Keep in mind to reference your surroundings.
Choosing an SSL Certificate

The first thing you must do, if you don’t already have one, is purchasing an SSL certificate. In general, there are three types of certificates to choose from:

  1. Domain Validation

It takes only a few minutes to issue email or DNS validation for a single domain or subdomain. These are typically available for as little as $9 a year.

  1. Business/Organizational Validation

A single domain or subdomain that needs business verification; is awarded in 1-3 days and offers a higher level of security or trust.

  1. Extra Verification

The necessity for business verification for a single domain or subdomain. It is issued in 2–7 days and offers a better level of security or confidence.

Ensuring features on your website are compatible

One of the most important stages is making sure the site will continue to function and run efficiently after the move. To do that, you must guarantee the use of the same protocol for all external features that your pages require.

The ability to use HTTPS should be available for all external dependencies. It includes social networks, Google AdSense, JavaScript, embedded video, certification labels, etc.

Getting ready for the migration

The number and size of pages on your website significantly affect how difficult the process is. A small site can be moved entirely at once. If you have too many URLs, you can do that in portions. Start with the specific subdomains that include the more important features and information as an example.

You can enable HTTPS while leaving HTTP in place till everything is in working order. In that case, use suitable tags to prevent duplication of content.

Just be aware that you will eventually lose some social media engagement metrics like sharing and likes.

Consider the timing of your intended course of action as well. Depending on the market, different times are optimal. When it comes to e-commerce; it is a good idea to avoid doing that throughout the holidays and other festive occasions.

The majority of businesses choose weekends or extended days off because they result in less traffic during the move. In any case, mentally prepare your team and yourself to deal with unforeseen problems and delays. This advice’s primary goal is to lessen those scenarios.

Activating HTTPS

After planning, it’s time to launch and enable HTTPS on your website.

Once the protocol is operational and the required setting has been completed correctly; it will already be possible to see the pages using HTTPS. It is necessary to confirm the SSL certificate installation.

To conduct the test, you can run HTTP and HTTPS simultaneously for 5 to 10 minutes. If nothing appears to be broken or acting strangely, you can stop the change.

Feature updates for HTTPS

Is HTTPS operational after step four? Great!

Updates to the features and internal links are now necessary. The architecture will be rearranged to be as lean as possible. It is to make it simpler for search engines to index the website.

One example of what this requires is avoiding repeated redirecting. As mentioned earlier, you may now check the unique Tags. You and your website’s SEO are valued by Google.

After then, it’s critical to look after exterior characteristics. The upgrade will guarantee that the loading speed of your website is raised or maintained. It will happen since you will once more be avoiding redundant redirection.

After confirming internal and external traits, the certificate’s implementation on the server can still be checked. You can identify any potential adjustments that need to be made. It includes support restrictions for specific browsers, using the test.

Upgrading the Google Search Console item for the website 

It may have come to your attention that Google Search Console treats addresses that start with “www”. And those that don’t as two independent sites, requiring the verification of specific elements on each. Both HTTP and HTTPS have the same problem.

Enabling HTTP/2 and HSTS


You can use HTTP/2, a new technology. It speeds up the downloading of material from your website after the HTTPS protocol is functioning. The vast majority of browsers currently support the norm, but only when a site is HTTPS.


While HTTP/2 can accelerate the loading of your web pages. HSTS aims to cut down on the several pointless requests sent to servers that only accept HTTPS traffic. Because the advanced feature is likely irrevocable once it is put into use, your webmaster is free to employ it.

HTTP to HTTPS conversion

When converting a website to HTTPS, it’s essential to translate HTTP-accessed URLs to HTTPS-accessible URLs.

Is it worthwhile to migrate to HTTPS?

Converting to HTTPS can benefit your website in several ways.

Given that Google discontinued supporting HTTP, the question now more closely resembles when rather than if. The question that remains is whether switching from HTTP to HTTPS by myself or hiring a professional is better.

The answer will depend on how at ease you are with the technical components of your website.

For those who are not programmers, it is permissible to use specialized aid when migrating. Even so, it’s essential to be knowledgeable about the right methods to protect your content. And then make the process as simple as possible.
