What is SSL?

SSL (Secure Sockets Layer or secure connection layer) is a global security standard that allows the transfer of encrypted data between a browser and a web server. It is used by millions of companies and individuals online to reduce the risk of theft and manipulation of confidential information (such as credit card numbers, usernames, passwords, emails, etc.) by hackers and thieves. identities Basically, the SSL layer allows two parties to have a private “conversation.”

To establish this secure connection, an SSL certificate (also called “digital certificate”) is installed on a web server, which has two functions:

Authenticate the identity of the website, guaranteeing visitors who are not in a fake site.

Encrypt the transmitted information.There are several websites that have been using SSL to protect the areas of their sites, such as user account pages and online payment systems. Normally, when a user is asked to connect to a website, the resulting page will be protected by SSL, which will encrypt the data that will be transmitted so that a third party cannot listen during the transmission process. This prevents others from seeing the data that is being transmitted. Only the user’s device and a secure server can recognize and decrypt the data. SSL helps keep the name, address and credit card information between the user and the merchant that the user is giving or providing. If there is no such encryption, online shopping sites could not provide the security necessary to carry out monetary transactions through the web. If a user visits a web address or website that contains “Https”, the letter “s” after the letters “HTTP” indicates that the website is secure and protected by an SSL protocol. Most of the time, several websites use SSL certificates to verify authenticity.
The following are the main objectives of SSL:

Data Protection

User privacy is guaranteed by a series of protocols that include the SSL registration protocol, the SSL Handshake protocol, the SSL Change Cipher Spec protocol and the SSL Alert protocol.

Client Server Authentication

The SSL protocol uses a standard cryptographic technique that will authenticate the client and the server.

Data integrity

All data is protected and secured so that it cannot be manipulated. This ensures that no changes are made to packages or information.
