What's the difference between HTTP and HTTPS?

HTTP (Hypertext Transfer Protocol) is a protocol used for transferring data over the internet. It does not encrypt communication, which means that anyone can intercept and read the data. On the other hand, HTTPS (Secure Hypertext Transfer Protocol) is an extension of HTTP that uses encryption to secure communication between clients and servers.

Conclusion

In conclusion, sending an HTTP request over a secure connection (HTTPS) is a crucial step in protecting sensitive information. By understanding the implications of this practice, individuals and organizations can take necessary precautions to prevent data breaches and protect their online security.
