HTTPS stands for Hypertext Transfer Protocol Secure.
It is a secure version of the standard Hypertext Transfer Protocol (HTTP) used for communication between a web browser and a web server. HTTPS ensures that data transmitted between the browser and server is encrypted and protected from unauthorized access.
Here are some key points about HTTPS:
1. Encryption: The primary purpose of HTTPS is to provide a secure and encrypted connection between the browser and the server. It uses SSL (Secure Sockets Layer) or its successor, TLS (Transport Layer Security), protocols to encrypt data and protect it from being intercepted or tampered with during transmission.
2. Data Security: HTTPS safeguards sensitive information transmitted over the internet, such as passwords, credit card details, and personal data. By encrypting the data, it prevents unauthorized individuals from accessing or manipulating the information.
3. SSL/TLS Certificates: Websites that use HTTPS require an SSL/TLS certificate, which is a digital certificate that verifies the authenticity of the website and enables encryption. These certificates are issued by trusted third-party Certificate Authorities (CAs) and contain information about the website and the encryption key.
4. Trust and Authentication: HTTPS provides authentication and verification of the server’s identity to the browser. When a user visits an HTTPS website, their browser checks the SSL/TLS certificate to ensure it is valid and issued by a trusted CA. This verification process helps establish trust and prevents users from accessing malicious or fake websites.

5. Padlock Symbol and Green Address Bar: HTTPS-enabled websites are indicated by a padlock symbol in the browser’s address bar, along with the “https://” protocol prefix. Extended Validation (EV) certificates display a green address bar, providing enhanced visual assurance of the website’s security.
6. SEO and Ranking Benefits: Search engines like Google consider HTTPS as a ranking factor. Websites using HTTPS may receive a small boost in search engine rankings compared to those using plain HTTP. Implementing HTTPS can contribute to better visibility and credibility in search results.
7. HTTP/2 Support: HTTPS is fully compatible with HTTP/2, the latest version of the HTTP protocol. HTTP/2 offers performance improvements, multiplexing, and server push capabilities, enhancing the speed and efficiency of website loading.
8. Evolving Security Standards: HTTPS and the SSL/TLS protocols are continually evolving to address emerging security vulnerabilities. It is essential to keep up with the latest security updates and best practices to maintain the integrity of the HTTPS implementation.
HTTPS is a secure version of HTTP that encrypts data transmission between web browsers and servers. It ensures confidentiality, integrity, and authenticity of the data, protecting users’ sensitive information and establishing trust in online communication.
