The Plain Http Request Was Sent To Https Port

HTTP (Hypertext Transfer Protocol) is a plain, unencrypted protocol used for transferring data over the internet. While it may seem like an old-fashioned method, HTTP remains a popular choice for online applications due to its simplicity and ease of use.

HTTPS (Hypertext Transfer Protocol Secure), on the other hand, is a secure variant of HTTP that uses encryption to protect data in transit. In 2014, Google announced plans to transition all its websites to HTTPS, citing security concerns over data interception by third-party actors.

Differences Between Http AndHttps Protocols

The key differences between HTTP and HTTPS protocols are the use of encryption and secure connections. HTTP does not provide any encryption, making it an insecure protocol for sensitive information. In contrast, HTTPS uses Transport Layer Security (TLS) or Secure Sockets Layer (SSL) to encrypt data in transit.

How Does TLS/SSL Work?

TLSTL/SSL is a cryptographic protocol that establishes a secure connection between the client and server. It works by authenticating the server's identity and establishing a shared secret key. This allows for encryption of data in transit, making it impossible for third-party actors to intercept or read sensitive information.

A Sample Code Example

const https = require('https');
const fs = require('fs');

function writeData(data) {
  const options = {
    hostname: 'example.com',
    port: 443,
    protocol: https,
    rejectUnauthorized: true
  };

  https.get(options, (res) => {
    res.on('data', (chunk) => {
      fs.write('file.txt', chunk);
    });
  }).on('error', (err) => {
    console.error(err);
  });
}

writeData('Hello World!');

Conclusion

In conclusion, HTTP and HTTPS are two distinct protocols that differ in their encryption methods. While HTTP remains a popular choice for online applications due to its simplicity and ease of use, HTTPS is the recommended protocol for secure online connections. By understanding the differences between these two protocols, developers can make informed decisions about which one to use in their applications.
