HTTPS stands for Hypertext Transfer Protocol Secure. It is a secure version of the HTTP protocol, which is a standard protocol used for transmitting data over the internet. HTTPS provides a secure communication layer by encrypting the data exchanged between a web browser and a website.
The main purpose of using HTTPS is to ensure confidentiality and integrity of data during transmission. It uses encryption algorithms to convert the plain text data into an unreadable format, making it difficult for unauthorized users to access or intercept the information. This protects sensitive data such as login credentials, personal information, and financial details from being compromised.
HTTPS employs the use of digital certificates, also known as SSL/TLS certificates, to authenticate the identity of the website and establish a secure connection. These certificates are issued by trusted third-party organizations known as Certificate Authorities (CAs). When a user visits a website with HTTPS, their browser checks the authenticity of the website's digital certificate to verify its identity. If the certificate is valid, the browser establishes a secure connection.
The use of HTTPS can be identified by the presence of a padlock icon in the browser's address bar, along with the prefix "https://" instead of the standard "http://". This indicates that the website is using a secure connection, ensuring that the data transmitted between the browser and the website is encrypted and protected.
Overall, HTTPS plays a crucial role in ensuring secure communication over the internet, safeguarding sensitive information from potential threats and unauthorized access.
