https is called a secure hypertext transfer protocol. It uses TCP port 443, and its data will be encrypted with the public key in PKI, so that the data packets captured by the packet capture tool cannot see the content of the packet, and the security is greatly improved. The private key in the PKI is used to decrypt the data.Therefore, some websites with relatively high security, such as online banking and e-commerce websites, need to be accessed with https!
