Considering the rapid growth the internet world keeps experiencing, it’s proven that SSL security protocol should become an integral tool needed to ensure the security of information that passes through the web. And there’s no other better security tool than the SSL certificate.
However, not everyone is familiar with the SSL certificate, leaving them with so many questions like, “what is an SSL certificate, how it works, how much it cost, and many more.” You can find answers to these pressing questions below.
WHAT IS SSL?
SSL stands for Secure Socket Layer (SSL). SSL is a security protocol that ensures encrypted communication between a web server and an Internet user. It encrypts all data transferred between the server and the user, using an encryption key placed on the server. It won’t be easy to establish a secured connection on your website if your website does not have an SSL certificate. And this means that the information transmitted is not linked to a cryptographic key.
SSL, also known as TLD (Transport layer security), is developed to help you achieve the following. And they are authenticating your website server, guarantee that the information shared between an internet user and the website stays confidential, ensuring shared data authenticity and integrity, and other security protocol purposes.
SSL authorizes the safe exchange of sensitive data such as credit card numbers, login credentials, social security number, etc., making it difficult for an internet attacker or cyber-criminal to gain access to this information.
SSL certificates come with a key pair: a public and a private key. These keys synergize to establish an encrypted connection void of attack threats.
In the SSL certificates is information such as;
- Certificate holder’s name
- Certificate’s serial number and expiration
- Certificate holder’s public key.
HOW DOES AN SSL CERTIFICATE work?
SSL carries out its work through the use of public-key cryptography. This cryptography uses two keys – a private key and a public key – to transit information between a user and a website, ensuring a safe passage of information.
The SSL protocol creates a communication channel between the user and the server, regardless of the protocol used. It thus secures transactions on the web (HTTP protocol) or connections via FTP, IMAP or POP protocol.
This communication channel is an opaque tunnel which prevents anyone from seeing what passes through it, thus ensuring confidentiality and transparency between the user and the website.
WHAT IS THE COST OF AN SSL CERTIFICATE?
The cost of an SSL certificate will depend on your website’s hosting provider, the provider through which it purchases the certificate and the type of certificate purchased. It is quite essential to know that there are different types of SSL certificates:
Single Domain – This type of SSL certificate is only valid for a single domain URL.
Multi-Domain – This SSL is known as Universal Communication Certificate (UCC). It secures multiple domain names and numerous hostnames, all under a domain name. You can define a primary domain and add up to 99 additional Alternate Domain Names (SANs) in a single certificate. This is ideal for businesses with multiple sub domains and URLs for different departments, product lines, or geographic locations.
Wildcard – This type of certificate is used to secure any subdomains you may have for a single domain.
When choosing your SSL certificate, it’s best to check with your web host, marketing agency, or IT department to make sure you’re choosing the right option for your entire business.
