HTTPS (Hypertext Transfer Protocol Secure) is a protocol thanks to which it is possible to display websites. It is an encrypted variant of HTTP. Because this is a secure protocol, it is usually not possible to catch the communication between the browser and server (and exploit data obtained). It is used especially for sensitive data such as personal information, passwords or credit card numbers.
From a technical point of view, HTTPS is an encrypted protocol application for transfer of objects of any type (e.g. pages, images, …) between the web server and browser. HTTPS uses the HTTP protocol and the data transmitted is encrypted using SSL or TLS.
Other protocols used on the Internet:
- HTTP (Hypertext Transfer Protocol)
- FTP (File Transfer Protocol)
- SMTP
- POP3
- IMAP
Use of HTTPS in practice: HTTPS on the web should be used when receiving orders from customers online, work with sensitive data (personal data, numbers of licenses, credit cards), if your system has a high importance (financial institutions, government and public administration), or just want to carry the communication on your site safely.
