HTTPS
When talking about VPN, we must first introduce HTTPS, which is also an encrypted application, but before that, HTTP must be introduced first. Http is called Hyper Text Transfer Protocol (H yper Text Transfer Protocol ) and is used to transmit data on the Internet. The steps for transmitting data are: The client sends a request to the server. After namibia whatsapp phone number the server receives it, it also sends an identity confirmation. The request goes back, and finally the client sends the information back to the server. This step is the so-called TCP transport protocol . During this transmission process, all information is in clear text, which means that it is easily snooped and stolen by malicious eavesdroppers. In order to prevent this from happening, the HTTPS Hypertext Transfer Security Protocol ( Hyper T ext T ransfer Protocol Secure ), Https allows data to be transmitted in ciphertext by encrypting the original Http. This encryption, called SSL/TLS, ensures the security when we transmit data . Now that we already have HTTPS, do we still need a VPN? At this time, we will introduce what a VPN is.
