Many users know port 80 and port 443, but they don't know I don't know. What's the difference between port 80 and port 443? Feifei will share it with you today ~
Hypertext transfer protocol
Service: http Hypertext Transfer Protocol
Description: used for web browsing, the server listens to the port requested by the web client. You can add quot:80gt；; To the HTTP address. Because the default port of the web browsing service is 80, you only need to enter the URL instead of quot:80gt；; For example,
Port 43
Service: Https
Description: Web browsing port, another HTTP that can provide encryption and transmission through a secure port. Some websites with high security requirements, such as banks, securities, shopping, etc. They all use HTTPS service, so that the information exchange of these websites can prevent others from seeing it, and others can grab the package to obtain encrypted data, thus ensuring the security of the transaction. The URL starts with
The difference between port 80 and port 443
1. Different protocols
Port 80 is an HTTP port, that is, hypertext transfer protocol is open. This is the most commonly used protocol for surfing the Internet, which is mainly used for WWW, that is, the protocol for transmitting information on the World Wide Web.
The 43-port service HTTPS can be said to be HTTP based on SSL secure connection. SSL/TLS runs at a level higher than TCP/IP, but lower than the application layer where HTTP is located. Therefore, HTTP can establish a connection on the basis of SSL connection, thus realizing the security and confidentiality of HTTP connection. Therefore, HTTPS is actually a combination of two protocols, namely SSL at the transport layer and HTTP at the application layer.
2. Different port vulnerabilities.
Port 80: Some Trojans can use port 80 to attack computers, such as Executor and RingZero.
Port 43: HTTPS services are generally protected by SSL, but SSL vulnerabilities may be attacked by hackers, such as invading the online banking system and stealing credit card accounts.
3. Different operations
Port 80 is created by adding quot:80gt；; To the HTTP address. Because the default port number of the web browsing service is 80, you only need to enter the URL instead of quot:80gt；;
43 port URL starts with
