With all the acronyms and abbreviations in technology, learning about simple computing terms, definitions, and systems is tough. From HTTP to MySQL, and DDoS to SaaS, you’d think everyone in technology didn’t have enough time to write full words. However, abbreviations are a reality of embracing computing and web design, so if you can’t beat ’em, join ’em! In the world of WordPress, a frequent situation we see is the comparison between SSH vs SSL.<\/p>\n\n\n\n

What do these abbreviations mean, and how do they affect your work on a WordPress website, or any type of site for that matter?<\/p>\n\n\n\n

Is there any reason to understand the inner workings of SSL? Does the SSH vs SSL comparison make sense? Or do they simply get confused because of the similar letters? <\/p>\n\n\n\n

These are all valid questions, so keep reading to learn more about SSH vs SSL and what they both mean for you as a WordPress user. <\/p>\n<\/div>\n\n\n\n

SSH vs SSL: What’s the difference?<\/h2>\n\n\n\n

To begin our analysis, we’ll explain what the actual abbreviations stand for and link to additional resources that dive deeper into the topics. <\/p>\n\n\n\n

What is SSH?<\/h3>\n\n\n\n

SSH stands for “Secure Shell.”<\/p>\n\n\n\n

It’s a protocol that lets people control a server over the internet. <\/p>\n\n\n\n

If that doesn’t make any sense, we’ll explain how it works with an example. <\/p>\n\n\n\n

Overall, a secure shell connection occurs when a user has a server (often a hard drive or a simple computer). That person goes onto another computer not located in the same spot. They log onto the internet with a secure shell connection to completely control everything on the original server. That may involve adding new files, deleting some, or reformatting the disk. <\/p>\n\n\n\n

What’s the point of that?<\/h4>\n\n\n\n

Many servers are accessed via remote connections. When you run a website, there’s a good chance your site files are hosted on another server, in a different state, country, or at least a different room. <\/p>\n\n\n\n

You could walk to your hosting company and ask to see the server for a direct connection, but they probably wouldn’t let you tamper with their expensive servers, and it wouldn’t be practical to go there. <\/p>\n\n\n\n

Therefore, a remote internet connection is required. <\/p>\n\n\n\n

Unfortunately, a remote connection opens up opportunities for bad guys to intercept data transfers. That’s where the SSH comes into play. <\/p>\n\n\n\n

The SSH secures the remote connection between your computer and the server. <\/p>\n\n\n\n

Why SSH is important for your WordPress site<\/h4>\n\n\n\n

If you have a WordPress website, you have several hosting options<\/a>. One is to self-host<\/a>. This places your website files on a host’s servers, which are not near your immediate location. <\/p>\n\n\n\n

For beginners, paying for hosting often means forgetting about that technical process and leaving it up to the hosting professionals, especially if you get managed WordPress hosting<\/a>. <\/p>\n\n\n\n

As you learn more about WordPress, you may want to connect to the server and add your own files for things like themes, plugins, and custom code. If that’s the case, you’ll want to secure the remote connection. <\/p>\n\n\n\n

The reason for the SSH is so that your file transfers aren’t intercepted, or so that hackers don’t find a route to place their own software on that server. As a result, your website is more secure and nothing is stolen.<\/p>\n\n\n\n

How to obtain SSH on WordPress<\/h4>\n\n\n\n

Secure shell access is easiest to handle when it’s offered by your hosting company. Sometimes you have to turn on SSH access, but many times it’s on at all times. <\/p>\n\n\n\n

Speak to a customer support rep or salesperson at the hosting company of your choice to learn about its SSH offerings.<\/p>\n\n\n\n

In general, they’ll either say SSH isn’t available, that you can access it via a one-click button, or you must use an SSH key and a system like puTTY<\/a> (this process is typically only used by developers, but it’s not that difficult to walk through the steps if you’d like to try). <\/p>\n\n\n\n

\"SSL<\/figure>\n\n\n\n

You also may be able to find documentation from your host on how to connect to SSH. For instance, Kinsta has a nice guide here<\/a> if you use them. <\/p>\n\n\n\n

What is SSL?<\/h3>\n\n\n\n

SSL stands for “Secure Sockets Layer.”<\/a> <\/p>\n\n\n\n

Makes total sense, right? <\/p>\n\n\n\n

Well…maybe the actual words make it even more confusing. <\/p>\n\n\n\n

The simplest way to define a secure sockets layer is that it’s a data encryption tool for your website. <\/p>\n\n\n\n

An SSL connection encrypts (scrambles) the data being sent back and forth between a website and its user. This way, no one else can see what communications are happening. <\/p>\n\n\n\n

What’s the point of that?<\/h4>\n\n\n\n

Encrypting your communications on a website prevents hackers from grabbing personal or financial information without permission. <\/p>\n\n\n\n

Without SSL, it’s possible for a malicious actor to sit in between your web browser and the website you’re browsing to see the information that you’ve submitted, such as your password or credit card information.<\/p>\n\n\n\n

For example, if you’re using Wifi at your local coffee shop, someone malicious who’s connected to that same Wifi connection could snoop on all the data that you send between your web browser and the website without SSL<\/em>.<\/p>\n\n\n\n

However, SSL, and its companion HTTPS, scrambles those details for the outside world. The user and the website can still communicate as usual, but it’s like a jibberish language to anyone trying to snoop on that traffic.<\/p>\n\n\n\n

This improves privacy for all visitors on your website, which is particularly important when collecting personal details and credit payment information through eCommerce stores. <\/p>\n\n\n\n

Why SSL is important for your WordPress site<\/h4>\n\n\n\n

Here’s why it’s important to have an SSL on your website:<\/p>\n\n\n\n
