A security certificate (SSL) encrypts the communication between a visitor (client) and the server. Indeed, during the visit of an Internet user on your website, the information that it enters either via the forms or any other means can be intercepted by a hacker. This is the reason why you must apply SSL to protect your customers' data first. And, also, to protect your company's reputation. In this article, we will see what a security certificate is. Then we will see how to install one for free.

About the security certificate

You certainly want to find out what an SSL is? In this section we say more.

What is an SSL security certificate?  

An SSL (Secure Sockets Layer) certificate is an electronic certificate that authenticates the identity of a website and enables an encrypted connection.   The SSL certificate activates the “HTTPS” protocol, in order to ensure a secure connection between the web server and the browser. SSL is generally used to secure banking transactions, data transfer and login information. In the digital age, having an SSL is essential to have online visibility. Indeed, search engines like Google disadvantage companies that do not have SSL.

How it works  

SSL is a protocol used to encrypt and authenticate data sent between your browser and a web server. It harnesses the power of two keys are long strings. One of the strings is called private key and the other public key. The public key is known to your server and available in the public domain. It can be used to encrypt any message on your site.  

Why use an SSL certificate on your site  

For businesses, an SSL certificate is required to obtain an HTTPS web address. HTTPS is the secure form of an HTTP address. This means that HTTPS websites are protected by the SSL protocol. This is a way of alerting users that the site may be dangerous, and it encourages companies to migrate to an HTTPS address.   SSL certificates ensure the privacy of site visitors and the authenticity of the website so that users can share their private information with confidence. Personal information like, credit card numbers, health insurance or financial information.  

Advantages of the SSL certificate  

The SSL certificate has a few benefits that can help you in selecting a certificate for your website.  

Privacy  

The SSL certificate ensures the confidentiality of your data and prevents hackers from hacking your data. In other words, it reduces the hacking of information exchanged between the server and the browser. It allows to authenticate a site and assures the visitor that it is indeed the official site of the company sought. You can also add the logo of the company producing the SSL certificate to your site, another guarantee of trust for your visitors and customers.  

An asset for e-commerce sites  

The certificate is of great importance for e-commerce sites. It protects and secures the data and information of your users as much as possible. We have found that most visitors are afraid to fill in their information such as bank details on an unsecured site. So if you have an SSL certificate, your customers will feel safe and comfortable entering their personal information.  

Easy installation  

It is possible to install an SSL certificate at the hosting level of your website. For example, if you have a site that only has a few pages, having the SSL certificate is not a necessity until the site is still collecting sensitive data from your users.  

Disadvantages  

Although there are advantages, it can also present problems.

Very high cost  

There are free SSL certificates, but it is more recommended to opt for a paid SSL certificate. Prices vary depending on the type of certificate you choose. The cost may be higher if you wish to have an additional level of security.  

Complex proxy caching configuration  

Another problem of SSL certificate is the complex configuration of proxy caching system on your web server. All of your encrypted content will not be able to be cached due to the incorrect caching configuration. It is possible to work around this problem by adding a server to handle the encryption before it reaches the caching server. Encrypted content cannot be cached. To work around this problem, you need to add. This will require additional costs, but it's a good way to ensure that you encrypt your visitors' data when they access your website.  

Web address confused  

If your SSL certificate is not properly configured and some files are still served over HTTP rather than HTTPS, visitors will receive a warning message in their browser. These warnings will tell them that some of the data is not protected. Therefore, it may interfere with some visitors browsing your website.
