When you visit any website, have you ever noticed the website URL? Some websites may start with the http://at the beginning of the URL, and some might have HTTPS:// at the start. I hope you have noticed the extra “s“ at the end.
What is SSL certificate? The “SSL” stands for “Secure Sockets Layer.”. The SSL is the security symbol that enables the website to process the data securely. The browser uses the required guideline while crawling the website and displaying the content to the end-user. The data is transferred using the encryption method to protect it while moving from point A to point B.
For example, when buying the product online, you have to put your payment details to make the payment. The payment details are highly secure. The website that accepts the payment online must have the SSL certificate enabled. You will see the notification window at the top of the browser giving you an alert message that you should not use sensitive information on the website due to an inactive SSL certificate.
As a consumer, you should know how to identify secure and non-secure websites when making online payments. Your data would be compromised if you are not taking precautions while using the payment details online.

What Is TLS?
The TLS stands for Transport Layer Security. The TSL is the data security protocol used by the companies while communicating with the data from one server to another without disclosing the exact file. The data is encrypted and protected from the data breach.
The primary objective of using the TLS is to protect the data while two applications are communicating on the internet. For example, when a web browser loads the website, the website’s information is transported in the encrypted file to the browser and display to the user on their screen. Only the browser and the website would have the key to access the data and communicate. A third-party application cannot read the active connection between the browser and the website. Many online applications such as email, messaging, voice-over IP uses the TLS technology to transport data. It is designed for web security.
What Is SSH?
The SSH or SSH protocol is also known as the Secure Shell, is a method to connect two applications securely on the remote login. You can log in from one computer to another using the SSH protocol securely. Login gives access to the essential data on the server or website. Therefore, reliable security integration is needed to protect the data from the hacker. SSH provides robust encryption to the data and nullifies the chance of the unauthentic login. Secure Shell gives you access to the strong password authentication with the public key for authentication. It encrypts the data communication between two systems over the open network.
Use SSH to create secure tunnels for the application protocol. You can run X windows system graphical session remotely on the SSH server. By default, the SSH server follows the standard transmission control protocol (TCP) with port 22 enabled.

SSL vs. TLS vs. HTTPS
SSL (Secure Sockets Layer) is the oldest method used for military and research purposes. The SSL gradually gain popularity, and it was released for commercial use in the early age of the internet to provide security to the data on the web. SSL provided the needed protection to the online data, financial documents, payments, and personal information on the web.
TLS is the upgraded version of the SSL. The security experts have detected some flows in the SSL method, which need to be fixed. The TLS protocol was developed to compensate for the problem and provide better and reliable protection to online data transport. New versions of the TLS are released with bug fixes and added safety measures to make the web secure.

HTTPS is the secure version of the standard HTTP protocol that defines how messages are exchanged on the web. HTTPS website uses an additional layer of protection using the SSL/TLS certificate. It is a sublayer that protects the data from the hacker.
HTTPS in the website URL indicates the site is using the secure path to exchange the data and store it on the server. Communication done between browser and website is secure. Users’ information, payment details, users’ inputs are all securely transported to the server in the encrypted format using the SSL/TLS certificates. Even if the data is lost during the transportation process, the receiver of the data will not be able to decrypt it. It would require authentication, which can be found only on the two websites that exchange the data.
SSL vs. TLS, Which Is More Secure?
Now let’s talk about TLS certificate vs SSL. TLS is considered more secure compared to the SSL due to its added security layer. TLS has backward compatibility support where two websites can securely connect when SSL is activated. Another benefit that attracts more developers to the TLS is the permission to build the connection to secure and ensure gateway over a single port.
TLS is gaining more popularity in the developer community. It is possible that in the future majority of the web application would be powered by the TLS certificate. Due to is multiple levels of the encryption method, the TLS is stand out as the more reliable technology that may change the way two applications communicate with each other on the web with high security.
I hope you have understood the difference between the SSL vs. TLS vs. HTTPS. Every method has its pros and cons. Some developers might argue the TLS certificate is better than the SSL certificate.
The difference between the SSL vs. TLS can be observed on the various discussion forum. TLS versions are frequently updated and release for commercial use. Applying for the secure certificate would give you better security for the user’s data . Data encryption is a powerful tool that technology has given us to protect personal information on the web. Knowing about the web securities and various protocol would help you to make your website secure on the web.
