An SSL certificate , where the acronym stands for "Secure Sockets Layer", is a cryptographic protocol that authenticates the identity of a website and protects , through SSL technology, the transfer of data between browsers and servers , thus avoiding intrusions by third parties .When an Internet user sends confidential data to a web server, his browser accesses the server's certificate and establishes a secure connection ; protection from fraud and theft is therefore activated, a fundamental aspect in particular for those sites that provide online services and which involve the exchange of sensitive information and e-commerce sites.Having the certification therefore not only guarantees the reliability


of the site but also allows you to encrypt the data making it Special Data indecipherable , in this way the communication flow is protected and the information transmitted remains confidential .Adding the SSL certificate to the domain also means moving towards the adoption of the HTTPS (HyperText Transfer Protocol over Secure Socket Layer) protocol for your website , a highly advisable step given the new Google regulations .Although the well-known search engine had already announced for some time that it wanted to make users' experience on the web more secure, it recently issued a new communication indicating that from July 2018 sites still in HTTP will be clearly flagged as unsafe.What an SSL certificate looks likeThe SSL certification is made up of two keys , one private (private key) and one public (public key) and specific





identification data such as the name of the domain, the subdomain, the expiration date and the exhibitor. The certificate also has a certain validity period which corresponds to the period of time in which it can be used.Any SSL certificate contains precise information :The name of the person who holds the certificateThe serial number and expiration date of the certificateA copy of the certificate holder's public keyThe digital signature of the certificate issuing authorityAfter adding the SSL certificate to your site, the domain will be introduced in the navigation bar by an “https” and a green padlock to demonstrate that you are making a secure connection.
