The difference between http proxy and https proxy

  https is an encrypted version of http. The biggest difference between the two is this. http is transmitted in plain text. During the transmission, the visitor’s information may be leaked and tampered with, so an SSL layer is added to the TCP/IP protocol layer. , The main thing is to encrypt the transmitted information.

The difference between http proxy and https proxy

  HTTP

  It is a transfer protocol used to transfer hypertext on the Internet. It is an HTTP application protocol running on top of the TCP/IP protocol suite, which can make the browser more efficient and reduce network transmission. In addition to HTML files, any server also has an HTTP resident program for responding to user requests. Your browser is an HTTP client and sends a request to the server. When a start file is entered in the browser or a hyperlink is clicked, the browser sends an HTTP request to the server, which is sent to the IP address specified URL. The resident program receives the request, and returns the requested file after performing the necessary operations.

  HTTPS

  It was developed by Netscape and built into its browser, used to compress and decompress data, and return the results sent back on the network. HTTPS actually uses Netscape’s Full Socket Layer (SSL) as a sub-layer of the HTTP application layer. (HTTPS uses port 443 instead of port 80 like HTTP to communicate with TCP/IP.) SSL uses 40-bit keywords as the RC4 stream encryption algorithm, which is suitable for the encryption of commercial information. HTTPS and SSL support the use of X.509 digital authentication, and the user can confirm who the sender is if necessary.
