服务器443端口与80端口的区别

今天壹基比知曰为大家讲解一下这两个端口最大的区别就在于服务不同：

端口：80

服务：HTTP

说明：用于网页浏览。木ma Executor开放此端口

端口：443

服务：Https

说明：网页浏览端口，能提供加密和通过安全端口传输的另一种HTTP。

443端口即网页浏览端口，主要是用于HTTPS服务，是提供加密和通过安全端口传输的另一种HTTP。在一些对安全性要求较高的网站，比如银行、证券、购物等，都采用HTTPS服务，这样在这些网站上的交换信息，其他人抓包获取到的是加密数据，保证了交易的安全性。网页的地址以https://开始，而不是常见的http://。

80端口是为HTTP（HyperText Transport Protocol)即超文本传输协议开放的，此为上网冲浪使用次数最多的协议，主要用于WWW（World Wide Web）即万维网传输信息的协议。可以通过HTTP地址（即常说的“网址”）加“: 80”来访问网站，因为浏览网页服务默认的端口号都是80，因此只需输入网址即可，不用输入“: 80”了。

HTTPS（Secure Hypertext Transfer Protocol）安全超文本传输协议 它是一个安全通信通道，它基于HTTP开发，用于在客户计算机和服务器之间交换信息。它使用安全套接字层(SSL)进行信息交换，简单来说它是HTTP的安全版。

HTTPS和HTTP的区别：

https协议需要到ca申请证书，一般免费证书很少，需要交费。

http是超文本传输协议，信息是明文传输，https 则是具有安全性的ssl加密传输协议

http和https使用的是完全不同的连接方式用的端口也不一样,前者是80,后者是443。

http的连接很简单,是无状态的 HTTPS协议是由SSL+HTTP协议构建的可进行加密传输、身份认证的网络协议 要比http协议安全

Today, I would like to explain to you that the biggest difference between these two ports is the service difference:

Port: 80

Service: http

Description: used for web browsing. Ma executor opens this port

Port: 443

Service: HTTPS

Description: Web browsing port, can provide encryption and through the security port transmission of another http.

Port 443 is a web browsing port, which is mainly used for HTTPS service. It is another HTTP that provides encryption and transmission through a secure port. In some websites with high security requirements, such as banks, securities, shopping, etc., HTTPS services are used. In this way, information exchange on these websites, others capture encrypted data to ensure the security of transactions. The address of a web page starts with HTTPS: / /, not the usual http: / /.

Port 80 is open for HTTP (Hypertext Transport Protocol), which is the most frequently used protocol for surfing the Internet. It is mainly used for the world wide web (WWW) to transmit information. You can visit the website by adding ": 80" to the HTTP address (i.e. "website address"). Because the default port number of web browsing service is 80, you only need to enter the website address instead of ": 80".

HTTPS (Secure Hypertext Transfer Protocol) is a secure communication channel, which is developed based on HTTP and used to exchange information between client computer and server. It uses secure socket layer (SSL) for information exchange, which is simply a secure version of HTTP.

The difference between HTTPS and http:

HTTPS protocol needs to apply for certificate from ca. generally, there are few free certificates, which need to be paid.

HTTP is hypertext transmission protocol, information is plaintext transmission, and HTTPS is SSL encrypted transmission protocol with security

HTTP and HTTPS use different ports for different connection modes. The former is 80, and the latter is 443.

The connection of HTTP is very simple. The stateless HTTPS protocol is a network protocol constructed by SSL + HTTP protocol that can carry out encrypted transmission and identity authentication, which is more secure than HTTP protocol
