What is SSL Certificate and Why is it Important?

SSL certificates and HTTPS are the favorite words of recent days. Owners of websites, online companies, website visitors, users of online payment portals, in short, anyone doing anything on the Internet should be familiar with HTTPS and SSL Certificates.

These terms can be a bit complicated for non-technical staff, but cyber security has become a necessity for all Internet users; Especially when it comes to frequent cyber attacks and malware. You can tell if a page is SSL from the lock icon in the address bar. Depending on the SSL type, the address bar may also be green. Also type yazın https: // built-in, no ”http: // at the beginning of the address.

HTTP (Hypertext Transfer Protocol) is an application layer request response protocol that occurs in the client-server model. A web browser that acts as a client sends an HTTP request to the server and the server responds to this message. In simple words, it is the standard protocol used to send hypertext documents from a Worldwide Network (www) source to a destination.

Although this protocol has been used for years, HTTP is not very secure. HTTP has evolved over time to HTTPS. HTTPS is the most widely used protocol for secure communication on a computer network. Communication in this protocol is via an encrypted connection with SSL (Secure Sockets Layer) or TLS (Transport Layer Security). HTTPS approves the visited website and instantly protects the privacy and integrity of the data. Cybercriminals are trying to capture this data in the middle man attacks (MitM).

Previously, HTTPS connections were primarily used for confidential transactions, e-commerce and payment transactions, and e-mail communications. Later, all types of websites started using HTTPS to maintain the authenticity of the page and to ensure confidentiality. HTTPS is currently preferred by a large majority. Google also places the highest HTTPS pages in search results pages.

Why do I need SSL?

By creating an encrypted communication between the SSL web server and the visitor's web browser, it is ensured that all private, confidential or confidential information is transmitted securely without being subject to various cyber attacks. If a website has the required SSL, all information between the web browser and the website server is encrypted and only the owner of the website can see it.

Online security is an important phenomenon for e-commerce companies; Lack of security has many serious consequences, mainly loss of business, loss of trust and reputation, and legal sanctions. The first step to avoid this is to obtain an SSL certificate for the website. Although this is an additional expense, e-commerce companies cannot protect their assets without security measures. Companies that did not use SSL did not succeed because they were increasingly concerned about the security of their customers visiting their websites.

SSL products vary. SSL certificates are issued after the domain name and organization are approved by the competent authority. SSL Certificate {9a2ff9c3fa3aab406b508a8b72b5114f6ac41b2a16a311054592a095e1387fd2} Compatible with 100 mobile devices We recommend starting with GeoTrust Quick SSL Premium.

Details about SSL certificates

SSL certificates are issued by legally authorized persons or entities. These certificates typically have the following details: if the page is secure, has a valid certificate, is secure, and uses secure resources. In addition, the validity period, due date, the purpose for which the certificate was received, who will be given, by whom information is given. Other details in SSL certificate; domain name, company name, address, city, state, country, type of certificate, protocol used (for example, TLS 1.2). password change and password used in the certificate. The signature algorithm, signature authentication algorithm, public key value, and certificate status are also included in the certificate.

SSL certificate approval

When a browser requests an HTTPS connection to a website, it will search for the site's certificate and check if it is still valid. It also checks whether the certificate is linked to a site that is not the site allowed by the author.
