Learn How to install SSL certificate (let’s encrypt) for free on Vultr WordPress site now. SSL Certificates are small data files that bind a cryptographic key digitally to the details of an organization. It activates the padlock and https protocol when installed on a web server and enables secure connections from a web server to a browser. SSL is typically used to secure credit card transactions, data transfers, and logins, and more recently, when browsing social media sites are secured, it is becoming the norm.
To start a secure browser session, a company needs to install the SSL Certificate on its web server. All web traffic between the web server and the web browser will be protected once a safe link is created.
The request protocol (also known as HTTP) can switch to HTTPs when a certificate is successfully enabled on your client, where the ‘S’ stands for’ secure.’ Depending on the type of certificate you purchase and on which browser you surf the internet, when you visit a website with an SSL Certificate installed, a browser will display a padlock or green bar in the browser.
How Does an SSL Certificate Work on Vultr or any server or site?
Tls Certificates use something called encryption of the public key.
A particular type of cryptography takes advantage of the power of two keys, long sequences of randomly generated numbers. One is called a private key and one is referred to as a public key. Your server knows a public key and is available in the public domain. Any email can be coded using it. When Alice sends a message to Bob, she must encrypt it with the public key from Bob, but the only way it can be decrypted is to open it with the private key from Bob. Bob is the only one to have his private key, so Bob is the only one to use it to unlock the message from Alice. If a hacker intercepts the message before it is unlocked by Bob, all they get is a cryptographic code they can’t break, even with a computer’s power.
If we look at this from a website point of view, there is communication between a website and a server. Alice and Bob are your homepage and client.

Where Do I Buy An SSL Certificate?

A trusted Certificate Authority must issue SSL certificates. The list of trusted root CA certificates is maintained by browsers, operating systems and mobile devices.
The Root Certificate shall be present on the machine of the end user in order to obtain the certificate. If the browser is not trusted, untrusted error messages will be presented to the end user. In the case of e-commerce, these errors lead to an immediate lack of trust in the website, and the company risks losing faith and revenue from most customers.
Organizations such as GlobalSign are considered trustworthy certification authorities. This is because of the trust that GlobalSign is an official certificate authority and can be relied on to provide trustworthy SSL certificates to sellers and browsers like Microsoft, Mozilla, Opera, Blackberry, Java, etc. As the Certificate Authority incorporates more applications, devices and browsers into its root, the better “recognition” the SSL certificate can provide.
Founded in 1996 in Europe, GlobalSign continues to be one of the longest-running certificate agencies in the region.
