11) Difference between http and https?

Question

Accepted Answer

HTTP is a protocol for transmitting data over the internet, while HTTPS is a secure version of HTTP that encrypts the data.

HTTP stands for Hypertext Transfer Protocol, while HTTPS stands for Hypertext Transfer Protocol Secure.
HTTP operates on port 80, while HTTPS operates on port 443.
HTTP is not secure and data is transmitted in plain text, while HTTPS uses SSL/TLS encryption to secure the data transmission.
HTTPS is commonly used for secure transactions, such as online banking, e-commerce, and sensitive data transfers.
Websites using HTTPS have a padlock icon in the browser's address bar, indicating a secure connection.

Accepted Answer

HTTP (Hypertext Transfer Protocol) and HTTPS (Hypertext Transfer Protocol Secure) are both protocols for transferring data over the internet, but they differ in their approach to security.

HTTP is an unencrypted protocol, which means that any data that is transferred over an HTTP connection is sent in plain text, making it vulnerable to interception and eavesdropping. This means that anyone who intercepts an HTTP request can read the request data, including any sensitive information such as login credentials or credit card numbers.

HTTPS, on the other hand, is a secure version of HTTP that uses encryption to protect data in transit. HTTPS uses SSL/TLS (Secure Sockets Layer/Transport Layer Security) to encrypt the data that is transferred between the client (such as a web browser) and the server (such as a website). This encryption makes it much more difficult for anyone to intercept and read the data being transmitted, providing a higher level of security for sensitive information.

In addition to encryption, HTTPS also provides authentication and integrity verification, which helps to ensure that the data being transmitted is not modified or tampered with during transmission. This is achieved through the use of digital certificates, which are issued by trusted certificate authorities and used to verify the identity of the server.

Overall, the main difference between HTTP and HTTPS is that HTTPS provides a higher level of security through encryption, authentication, and integrity verification, making it the preferred protocol for transmitting sensitive information over the internet.
