What You Need to Know About TLS and SSL

The subject of encryption can be a complicated topic for someone who is not or has never worked behind the scenes and on the technical side of things.

If you are not familiar with cybersecurity, the processes and terms associated with encryption can be a bit daunting and overwhelming when you do attempt to get a grasp on how things work. Having to catch up to others who are more versed in the topic can be intimidating enough to turn you off from it forever.

In this article, we hope to explain what you need to know about TLS and SSL, two cryptography-based protocols used in the encryption process.

What is SSL and TLS?

TLS is the acronym for Transport Layer Security.

TLS provides end-to-end security for data being sent between applications over the Internet. It is most well-known for being used in web browsers and can be recognized through the padlock icon that you see at the top of the page when a secure connection is secured.

While in transit from one party to the next, important files and data can become susceptible to hackers and can easily end up in the wrong hands. TLS is a protocol that encrypts the message and ensures secure delivery.

While TLS is becoming the standard for email security, not every email service supports the latest version, so ensuring that the email provider you have uses it is something you should definitely look into!

SSL is the acronym for Secure Sockets Layer.

SSL connects the visitor’s web browser with your website so that communication through the link is encrypted and secured. It can also be used to transfer emails, files, and other forms of communication in a secure way that cannot be hacked or accessed by a third-party.

SSL creates a unique, secure channel for communication to take place in that is only accessible to those involved. It should be noted that SSL is no longer used on its own, but only alongside TLS, which (in some ways) is just a newer and improved version of SSL.

Protocols and Certificates

Protocols and certificates are a major part of both TLS/SSL and in how these systems are authenticated and secured. While in transit, protocols and certificates will keep the private information secured and safely out of the reach of those who shouldn’t have access.

Certificates: Used to authenticate the user or device that is accessing the information to make sure they are the intended recipient. Your certificate will not be the same as the recipient’s certificate, but both will work to make sure the information is not accessed by the wrong person.

Protocols: Protocols aim to provide privacy and protection between two or more people who are in communication with one another. TLS is a cryptographic protocol providing end-to-end communication services, mostly used for messaging between multiple people and for online banking transactions.

How Does it All Work?

Now, let’s take a look at how TLS/SSL works in the encryption process.

The SSL and TLS process works to establish a secure connection between the server and the client so information can be encrypted and hidden from parties that are not involved.

An SSL/TLS certificate is installed through the web browser you are using and will automatically create two keys that are added to your server: a private one and a public one.

These two keys will work together to secure your platform and successfully encrypt the information you are viewing on the pages you visit while using this web browser.

When you visit a website, the server will verify your SSL/TLS certificate and then work in unison with it to create a secure connection between that specific website and the user. This process is called the ‘Handshake’ and ensures the safety of both users through whatever they are going to do on the website. This could involve banking information, sharing of personal information, or the process of accessing classified files and fights against them falling into the wrong hands.

You will now see a padlock icon next to the URL address you are visiting, which means the connection is complete and the encryption process was successful.

This is also when HTTPS (HTTP over SSL/TLS) comes into play. It encrypts and authenticates the information during transportation so it is not vulnerable.

To Finish Up…

This entire process might seem complicated and intimidating, but it’s important to take the time to learn the ins-and-outs of online security.

Your safety while online is nothing to take for granted and, by learning these systems, you can ensure yourself (as well as friends and family) that you are staying safe while cruising unknown websites.
