What is an SSL certificate, exactly?

A digital certificate or data file known as an SSL certificate is used to confirm the legitimacy or owner of a website. The data security standard known as Secure Sockets Layer, or SSL, forms an encrypted connection between your web browser & the website you are viewing.

Almost all trustworthy websites utilize SSL certificates because they enable web browsers to establish secure connections and check the security of websites. SSL certificates are particularly crucial for websites that handle credit card purchases and other online payments, enable data transfers while in transit, and store sensitive login information, such as social media and email providers.

Due to their great security, SSL certificates are also used by a lot of mobile apps, such as encrypted messaging apps.

  • An SSL certificate has the following details for authentication purposes:
  • The website name to which the certificate has been issued.
  • The name of the business that issued the certificate.
  • the certificate’s serial number.
  • The public key of the certificate holder.
  • the certificate-issuing authority’s digital signature.
  • The duration of the certificate, or the day it is valid until its expiration date.

What does SSL stand for?

Secure Sockets Layer is what SSL stands for. A web server & a web browser can establish an encrypted relationship thanks to the security standard known as SSL. An SSL certificate contains verified details about the owner of a website and authenticates the encrypted connection.

Because it validates the ownership and security of the domain, an SSL certificate inspires confidence in businesses that handle sensitive data, including personal information.

How do SSL certificates work?

Long strings of randomly generated numbers or public key cryptology, an encryption scheme based on two keys, are the methods by which SSL certificates function.

Your web browser is aware of the public key since it is part of the public domain. Your browser encrypts sensitive data, such as credit card numbers, before transferring it to a website using the public key. The website decrypts the data after it has been received using a private key. The private key needed to decrypt the encrypted data is only accessible by the website’s server.

Data encryption and decryption with SSL certificates are accomplished via a two-key encryption mechanism.Public and private encryption keys are the foundation of the encryption mechanism used by SSL certificates.

Types of SSL certificates

Depending on the data they must authenticate, SSL certificates come in a variety of forms. A server needs to supply more authentication information in order to obtain a more secure SSL certificate. A more secure SSL certificate is preferable if you’re submitting really sensitive data to a website because it shows that you can trust them more because they’ve disclosed more personal information.

The three categories of SSL certificate validations are as follows:

  • Domain Validation certificates do not require any further information; they merely authenticate the owner of the server that the website uses. Cybercriminals frequently employ DV SSL certificates, which are comparatively simple to obtain, to create the appearance of a reliable website.
  • Organization validation certificates need the organization, physical location, and domain name of a web server to be verified. OV SSL certificates are appropriate for websites that do not handle sensitive data and provide a moderate level of confidence.
  • The most challenging certificates to obtain, Extended Validation ones demand the most authentication data from a web server. The best level of security is achieved with EV SSL certificates, which are simple for your browser to validate. Also check  free vpn apps

What SSL is important

The reason SSL security certificates matter is because they inform your browser of the legitimacy of the website you are currently viewing. Additionally, they authenticate an encrypted connection, indicating that sharing confidential information with websites that have SSLs is secure.

The following information regarding the encryption and verification of SSL certificate security features:


When a website has an SSL certificate, it indicates that a reliable third party has confirmed its legitimacy by looking up information such as the owner and location of the website. Because they are not required to disclose any information, websites without SSL protection are dangerous to visit.


Data encryption is the technique of jumbling up information such that it cannot be decoded. Only a decryption key can be used to decode encrypted data. Websites lacking encryption may expose your data and make it more susceptible to theft.

Hackers may utilize your personal information to perpetrate identity theft or trade it on the dark web if it is ever taken or exposed in a data breach. If your data is ever compromised, SSL security helps stop hackers from misusing it since encryption is very difficult to break without a secret key. It is crucial to avoid sharing personal information with websites that lack SSL certificates for this reason.

Although SSL-certified websites contribute to the security of your data, they are limited to securing your connection to certain websites. To make sure that everything you do online is safe and secure, you’ll need a VPN to encrypt your whole internet connection.

How do websites get SSL certificates?

A certificate authority can provide websites with a valid SSL certificate (CA). The reliable, outside companies in charge of creating and distributing SSL certificates are known as SSL certificate authority. The CA will check the website’s ownership after it has submitted the required data, and if it is legitimate, it will then issue the certificate.

The public keys and login credentials that websites and web browsers use to encrypt data are also maintained by the certificate authority.

The SSL certification is installed on the server of a website after it is issued, and the website’s URL changes from http to https to show that all of its traffic is encrypted. A web browser can now quickly confirm a website’s legitimacy at this stage.

Are SSL certificates free?

An SSL certificate can be given for a price by the majority of SSL certificate authorities. However, you don’t have to go far if you’re a website owner wondering where to obtain an SSL certificate for nothing. Free SSL certificates are now a typical feature of many web hosting providers. This is a little step in a bigger campaign to encourage a more secure and safe internet.
