SSL, or Secure Sockets Layer, is an Internet security technology that uses encryption. Netscape created it in 1995 to maintain confidentiality, verification, and information protection in Internet interactions. SSL is the forerunner of today’s current TLS (Transport Layer Security) encryption. A website that uses SSL/TLS has “HTTPS” in its URL rather than “HTTP.” SSL is a technology that allows networked computers to create authenticated and encrypted connections. Although the SSL protocol is now deprecated and TLS stands in its stead, most people still prefer this sort of technology as ‘SSL.’ SSL establishes a secure connection between two workstations or devices communicating through the web or a private network.

SSL security encrypts sensitive data during transmission via algorithms, keeping it incomprehensible during the transit between websites, devices, and users. Secure Sockets Layer security protocols in various versions are commonly applied in the field, such as emails, texting, and instant messengers, voice over Internet protocol (VoIP), and web surfing. SSL security protects sensitive data, such as credit card information and financial details, from manipulation when transmitted between two systems. It also prevents unauthorized access, reading, or editing of any personal information. Holding this personal data out of the hands of the wrong person also helps to avoid identity theft. SSL also protects others from eavesdropping on our online activity and aids in the confidentiality information communicated via emails and chats.

What is an SSL certificate?

An SSL certificate is an electronic certificate that connects a website’s identification to a cryptographic key pair made up of a public key and a private key. The certificate’s public key enables a web browser to begin a secured communication connection with a web server using the TLS and HTTPS standards. The server secures the private key, which authenticates pages and other data. An Secure Sockets Layer certificate functions similarly to an Identification card or a badge in that it verifies that a person is who they claim to be. The server of a website or application stores and displays SSL certificates on the Internet. Certificate authorities issue Secure Sockets Layer certificates (CAs). However, you can get a domain with free SSL certificates using WEB HOSTING SERVICE providers like HOSTIERA.

Types of Certificates

Single-domain:

A single-domain Secure Sockets Layer certificate is only eligible for and protects one domain. Remember that you cannot use this certificate to defend subdomains or an entirely other domain.

Wildcard:

A wildcard Secure Sockets Layer certificate, like a single-domain certificate, applies to only one domain. However, it allows you to acquire a certification for one domain and use it for its subdomains.

Multi-domain:

Multi-domain SSL certificates, as the name implies, are eligible for numerous unrelated domains.
SSL certificates are also available in a variety of validation levels:

Domain Validation:

This is the most basic and least expensive level of certification. A company would only have to demonstrate ownership of the domain. It is the fastest validation available, and you will only use a few corporate paperwork to apply. Whenever you add a DNS to the CA, this verification occurs. The CA will verify the applicant’s right to own the domain getting filed for this certificate.

Organization Validation:

This is a more hands-on method in which the CA contacts the individual or entity requesting the certificate directly. These certifications are more reliable for users. Organization Validated SSL certificates provide a medium degree of security. However, the CA will first determine who possesses the domain and whether the organization is lawfully operating.

Extended Validation:

Before obtaining an Secure Sockets Layer certificate, a company must undergo a thorough background investigation. This certificate displays the padlock, HTTPS, company, and company location in the address bar to avoid being misunderstood bey a spam website. Extended Validation (SV) Secure Sockets Layer certificates are the most expensive to get, but they help demonstrate the authenticity of your site from the address bar. It assures customers that you are lawfully gathering the information required to carry out specific tasks, such as bank details for an e-commerce transaction.
