HTTPS (Hypertext Transfer Protocol Secure) is a secure version of the HTTP protocol used to transmit data over the web. It is the primary protocol used to access secure websites and is widely used in e-commerce, banking, and other secure transactions.
HTTPS is an extension of the HTTP protocol, used to securely transmit data over the web. It works by encrypting the data sent between the web server and the browser, making it difficult for hackers to intercept and read the data. HTTPS also provides authentication, ensuring that the user is connecting to the correct website.
When a web browser requests a page from an HTTPS-enabled website, the web server first sends a certificate to the browser. This certificate contains information about the website, such as the domain name, and is used to prove that the website is authentic. The browser then encrypts the data sent to the server using the website's public key. The server then decrypts the data using its private key.
In addition to encrypting data, HTTPS also provides other security features such as data integrity and non-repudiation. Data integrity ensures that the data sent between the server and the browser has not been tampered with, while non-repudiation ensures that the sender of the data cannot deny having sent it.
HTTPS was first introduced in 1994 as part of the Netscape Navigator web browser. It was designed to provide a secure connection between the web browser and the web server, allowing for secure transactions such as online banking and e-commerce.
In 1999, the Internet Engineering Task Force (IETF) released the first official version of the HTTPS protocol, known as TLS (Transport Layer Security). This version of the protocol is still in use today and has been updated several times since its initial release.
The main features of HTTPS include:
When a user visits a website using HTTPS, the web server sends a certificate to the browser. The browser then encrypts the data sent to the server using the website's public key. The server then decrypts the data using its private key. This ensures that the data is secure and cannot be read by anyone other than the intended recipient.
The main advantages of HTTPS include:
The main disadvantages of HTTPS include:
SSL (Secure Sockets Layer) is a related technology that is used to provide secure communication between two computers. SSL works by encrypting the data sent between the two computers, making it difficult for hackers to intercept and read the data.
