DIFFERENCES between HTTP vs HTTPS  Which is more secure? ▷ 2020

If you have reached this post it is because you are browsing the internet and surely you have done it with some frequency. Having surfed the internet it is very likely that you have realized that URLs usually start with the acronym “HTTP” or “HTTPS”, but you probably have no idea what that means, or what the differences are between one or the other.

We may or may not know that both HTTP and HTTPS are protocols And although we surely think not, it is really important to know about them, what they mean, how they differ and how they work on the internet.

At first glance the only difference between the two protocols could be a letter included at the end, but it is much more than this. It is of great importance to have at least a basic understanding of these protocols. For this reason we have prepared for you a simple explanation about what the acronyms of both mean and some other details that may be convenient to know.

What does the acronym HTTP mean in computing? Evolution and operation

http protocol

The acronym HTTP is the acronym for Hypertext Transport Protocol, which translates into Hypertext Transfer Protocol. Basically its function is described in its name, being a protocol to transfer information between server and client, is responsible for making sure that the data reaches its destination and that it is done correctly. It is considered a request-response type protocol that runs between the two agents mentioned.

As usual, the HTTP protocol does not store any information about the connections made, but once it is finished the browsing data is lost.

Without a doubt, HTTP is the most used protocol on the web. Since it occurred its development has evolved considerably having different versions to this day:

  • HTTP / 0.9: Initially it did not have a version number, it was added to it when a second version of the protocol emerged to differentiate one from the other. It was a single line protocol and did not use headers, so the only files that could be transferred were HTML.
  • HTTP / 1.0: This version had considerable advances allowing the GET, HEAD and POST request methods.
  • HTTP / 1.1: It was launched in 1997 and allows the customer to make multiple requests at the same time. In addition to being able to reuse the connection.
  • HTTP / 2: Although it does not modify the semantics of version 1.1, it includes several improvements with respect to it, such as the ability for a server to respond to multiple requests at the same time.

Despite having evolved, version 1.1 is still the most widely used worldwide. Well if HTTP is quite a vulnerable protocol, previously, Internet users did not need as much security to navigate, this because online purchases or banking operations were not carried out from the computer.

Differences between the HTTP and HTTPS protocol

HTTP vs HTTPS

The difference between these two protocols goes beyond adding a letter at the end. This letter, it should be clarified that adds the quality of “insurance” to the protocol. So, HTTPS is the acronym for Hypertext Transfer Protocol Secure, translated into Hypertext Transfer Protocol Secure. This letter “S” refers to an additional protocol called Secure Sockets Layer (SSL) that together with HTTP allow the transmission of encrypted information on the internet.

Use the protocol HTTPS is the safest way to surf the internet, Since all the information that we enter will be encrypted, which gives us the guarantee that the only ones who will be able to access this information are the client and the server.

HTTPS is used in activities that add the use of personal data, either in banking operations, emails or anywhere else where passwords or any confidential information must be entered

The only disadvantage of the HTTPS protocol over HTTP is that the speed in this is lower because the secure connection requires encryption and decryption work, which generates a certain slowness in the connection.

How to know if a web page is using the secure HTTPS protocol?

Identifying whether or not a page is using the HTTPS protocol, giving us connection security, is very simple. Simply look at the top, on the left, right at the beginning of the URL address, we can detail whether the protocol used is HTTP or HTTPS.

In the event that it has a box with a green padlock, we will know that the HTTPS protocol is working on that page and that the connection is encrypted and secure, and even if you wish, you will have the option to be able to observe the certificate of the web.

What is the SSL security certificate for a website?

The acronym SSL comes from English Secure Sockets Layer, which stands for Secure Connections Layer. SSL is a security protocol that, as we have said, is used in conjunction with HTTP to form the secure information transfer protocol.

The SSL certificate It is used to authenticate the identity of a website. It is a document that is used in order to provide security to users who browse a web page in order to show them that it is real and that they can trust it and enter their personal data without any risk.

The fact of having a certificate SSL makes our data is encrypted and therefore it will be transmitted securely, Likewise, we will have the certainty that it is free from the reach of any unwanted agent only by having access to it both the browser and the server, this caused by the use of mathematical algorithms and certain keys that can only be deciphered by these two agents.

Definitely, This gives us a guarantee of security to users who browse the web, good because it assures us that we are entering the correct site and also because we know that no one will be able to access our information.
