These two systems can be a server and a abonné (a magasinage website and a browser) or a server to server (for requête, a magasinage website and a browser).
For example, an vigilance with personally perceptible épreuve or with payroll épreuve is at risk.
SSL certificates must be installed on a company’s or organization’s website in order to safeguard online transactions and keep customer épreuve private and secure.

Credit card numbers and other financial épreuve, as well as names and addresses, are examples of potentially sentimentale épreuve being sent, and they need to be protected.
The procedure it undertakes is as follows:
- A browser or server tries to connect to an SSL-secured website (i.e., a web server).
- The web server is asked to identify itself by the browser or server.
- In response, the web server delivers a copy of its SSL certificate to the browser or server.
- The SSL certificate is checked by the browser or server to see if it is to be trusted. If it is, the web server receives a annonce.
- After that, the web server sends a digitally signed acknowledgment, which initiates an SSL-secured vacation.
- Then, encrypted data is transferred between the browser or server and the web server.
The term “SSL handshake” is used to describe this process. While it may appear to be a lengthy procedure, it is completed in milliseconds.
The term HTTPS (which stands for Hypertext Transfer Protocol Secure) appears in the URL when a website is secured by an SSL certificate. Only the letters HTTP – i.e., without the S for Secure – will appear if you don’t have an SSL certificate.
