The Hypertext Transfer Protocol HTTP protocol is used to pass information between a Web browser and a Web server, the HTTP protocol sends content in plaintext, does not provide data encryption in any way, and if an attacker intercepts a transmission message between a Web browser and a Web server, it can read the information directly, so HTTP protocol is not suitable for transmitting some sensitive information, such as credit card number, password and other payment information.In order to solve t

The Transfer-Encoding field indicates how the Web server encodes the response message body, such as Transfer-Encoding: chunked indicating that the Web server has made a chunked transfer of the response message body.

　　What does HTTPS mean? HTTPS is called hypertext Transfer Protocol over Secure socket Layer, the Chinese meaning of "Hypertext Transfer Protocol in the security of encrypted word layer", in simple terms is encrypted data transmission, popular saying is a secure connection. 　　HTTPS Secure Hypertext Transfer Protocol, which is a secure communication channel, bas

Nginx To configure SSL is very simple, whether it is to go to the certification Center to buy SSL security certificate or self-signed certificate, but recently a company OA needs, to have a chance to actually toss it. At first, full station encryption, all access to HTTP:80 request cast (rewrite) to HTTPS, and then automated test results said that the response speed is too slow, HTTPS is 30 times times slow

algorithms are exposed, the data remains secure as long as the second algorithm is not exposed.3) Improved completed message validation: Both TLS and SSLv3.0 provide completed messages to two endpoints, and the message that authenticated the interchange has not been changed. However, TLS bases this completed message on the PRF and HMAC values, which is also more secure than SSLv3.0.4) Consistent certificate processing: Unlike SSLv3.0, TLS attempts to specify the type of certificate that must be

There are many scenarios for using SSL on Python, and my main concern is to use Python to access HTTPS resources and to use Python to provide HTTPS services. (HTTPS is one of the SSL applications on the Web)I. Using python to access HTTPS websitesThis should be the simplest and most common scenario. We use Python as a

Basic knowledge Preparation: Before you understand the fundamentals of HTTPS, you need to understand the basics below.First, what is Https,tls,sslHTTPS, also known as HTTP over TLS. The predecessor of TLS is SSL,TLS 1.0, which is typically marked as SSL 3.1,TLS 1.1 for SSL 3.2,tls 1.2 for SSL 3.3. Describes the relationship between TLS (each sub-protocol) and HTTP in the TCP/IP protocol stack.Ii. difference
