What is SSL Certificate and SSL Certificate Checker? What are the different types of SSL Certificate issuing and validation techniques that certificate authority employ to provide the digital certificates to customers?
A digital certificate known as an SSL encrypts data exchanged between a website and the user’s browser while also authenticating the identity of the website. Secure Sockets Layer, sometimes known as SSL, is a protocol that enables secure internet communication.
An SSL certificate includes the name and location of the website owner in addition to a public key that may be used to encrypt data. Any data sent between a user’s browser and the website’s server when they access a website with an SSL certificate is encrypted and safeguarded against interception and modification.
Using an SSL certificate checker, you can determine whether a website has a valid SSL certificate and whether it is current and configured correctly. Online SSL certificate checkers come in a variety of forms, some of which are free to use and others of which demand a fee or subscription.
And SSL certificate checks offer details on the SSL certificate issuer, the certificate’s expiration date, and any problems or warnings that might point to a problem with the certificate or its setup. Website owners and administrators who want to make sure that their website is safe and set up correctly for secure communication over the internet may find this information valuable.
Certificate Authorities (CAs) use a variety of SSL certificate issuance and validation methods to offer consumers digital certificates and some of the methods includes:
- Domain Validated (DV) SSL Certificates: The most fundamental kind of SSL certificate, a DV certificate just confirms that the domain name is owned and registered by the customer. Before granting the certificate, the CA will normally send an email to the administrator or owner of the domain to verify control of the domain.
- Organization Validated (OV) SSL Certificates: This kind of SSL certificate checks that the company is a real business entity and often calls for the company to present identification from the government and business registration documents. Visitors to the website might be more confident that the company is reliable thanks to this.
- Extended Validation (EV) SSL Certificates: The organization must go through a rigorous validation process, which includes checking the organization’s identity and legality and verifying its legal and physical presence. This is the highest level of SSL certificate. A green address bar and the company name in web browsers are indicators of EV SSL certificates.
- Wildcard SSL Certificates: Customers that purchase this kind of SSL certificate can use it to secure several subdomains under a single domain. For instance, “www.merebatigray.com,” “blog.merebatigray.com,” “Jobs.merebatigray.com,” and other domains might all be secured using a wildcard SSL certificate for “*.merebatigray.com.”
- Multi-Domain SSL Certificates: This kind of SSL certificate makes it simpler to maintain SSL certificates for complicated setups by enabling customers to secure numerous domains and subdomains with a single certificate.
