HTTPS protocols: TLS, SSL, SNI, ALPN, PNP, snialpn
HTTPS is now widely used. It brings security while introducing more complicated concepts to the Web. This includes a series of network protocols that have never been seen before. Now, based on the principle of HTTPS, Harttle tries to interpret these protocols in the most popular way.
HTTPS Overview
HTTPS is an HTTP built on secure communication and uses transport layer encryption (TLS or SSL. The obj
SSL link, so that the server returns a suitable certificate based on the domain name. Currently, most operating systems and browsers are well-supported for SNI extensions, and the OpenSSL 0.9.8 has built this functionality, and the new Nginx is said to support SNI.to use SNI, you need both the client and server side to meet the conditions, but fortunately for modern browsers, most of them support SSLV3/TLS

The boss said that he would like to build a demo version of the time table tool for him to see and find a few solutions. He still prefers timesheet. I have never touched on Django before, and it is full of pitfalls in the process. The final steps are as follows:
1. Install Pip

Default: When the SSL protocol is used for handshake negotiation, the default is not to send the host name, that is, in the form of IP for HTTPS connection handshake negotiation, which leads to a problem, when there are multiple virtual hosts on a server using the same IP,Nginx will be an error in the Counter-generation!SNI (server Name Indication): is to solve a server, the same IP, the use of multiple domain name certificates, that is, using SSL to

Hackers can obtain false HTTPS authentication, Let's Encrypt, and take urgent measures
Web Application Security automatic scan service detecloud security researcher recently Frans rosé n found that TLS-SNI-01 and TLS-SNI-02 allow hackers to gain HTTPS authentication for others' Websites under specific circumstances.

I started working on Mitmproxy because I was bored with the interception tools I used. I have a long list of mild complaints-they don't have enough flexibility, they don't have enough programmability, most of them are written in Java (a language I don't like), and so on. The most serious problem, however, is opacity. The best tools are all closed-source and commercial.

First, we create three

Add another user? posts
To add other users ' posts to a user's timesheet (timeline), simply reuse some of the code that was written earlier. For example, you now know how to get a list of users that the current user is following. Also know how to get all the posts sent by a user. So you just have to modify the latter function a little so that it can accept a list of users instead of a single user.
Now just move the first function up a bit in the ind
