First of all, the content of this chapter is about WEB security, due to my knowledge limited this article may be wrong, if you have any questions can contact Uncle Wen (darrel.hsu@gmail.com ). Thank you very much for @ Sogl and @ Jianxin ~ The prevalence of WEB makes the network society richer, followed by security issues. If he is safe to accept user input and correctly display it, it is the pursuit of a vast number of WEB programs. One of them is to prevent XSS. (If you do not know XSS, you ca

CCF-CSP 201709-4 communication network, ccf-csp201709-4 Problem descriptionThe army of a country is composed of N departments. To improve security, M channels are established between departments. Each channel can only transmit information in one way, that is, a channel from department a to department B can only transmit information from a to B. Information can be transmitted in transit mode, that is, if a can pass the information to B and B can pass t

CSP Tetris (201604-2), csp201604-2Problem descriptionTetris is a casual game invented by Russian alexschey pakitov.The game is carried out on a 15-row, 10-column grid. Each grid on the grid may have been placed in a square or not. In each round, there will be a new section composed of four small blocks falling from the top of the square chart. Players can operate the plate and move it to the right position, when the bottom edge of a square in a plate

This is a creation in Article, where the information may have evolved or changed. The concurrency mechanism of the go language and the CSP concurrency model it uses CSP Concurrency modelThe CSP model was proposed in the 70 's to describe the concurrency model of two independent concurrent entities communicating via a shared communication channel (pipeline).

What is the difference between the actor model of Akka/erlang and the goroutine of the Go language and the CSP (communicating sequential Processes) model represented by channel channels?First of all, both are solutions to the concurrency model, and let's look at how it's defined and implemented:The actor model describes a set of axioms to avoid common problems with concurrent programming :1. All actor states are actor-local and cannot be accessed exte

First, IntroductionCSP is the abbreviation for Web Security Policy (Content security Policies). is a developer-defined security Policy statement that specifies a trusted source of content through the responsibilities that are constrained by the CSP (content can refer to remote resources such as scripts, pictures, style, and so on). By using the CSP protocol, you can prevent XSS attacks and allow the web t

ApplicationProgramThe general steps for encrypted communication using the crypto API are as follows: 1, include wincrypt. h 2. Call cryptacquirecontext () to obtain a handle of the key container in a CSP module; 3. The sender uses cryptimportkey () to import the certificate of the receiver to the CSP to obtain the public key of the receiver; 4. The sending method uses cryptgenkey () to randomly gene

+ private key. The certificate + public key can be made public. The private key is in USB key and cannot be obtained by anyone. After the USB key is inserted into the computer, the middleware program provided by the USB key manufacturer registers the certificate information to the Windows system, and finds the user certificate through the windows system during authentication in the application system, the certificate finds the corresponding private key in the USB key through the middleware of t

Because CSP can be tested only after being signed by Microsoft, and each change requires a new signature, which will not change the CSP debugging. Therefore, according to the instructions in cspdk, if you replace advapi32.dll in a 2 k operating system without a signature, follow the instructions The installation and replacement of Win2k operating systems from the Internet all fail. The first problem is that

After filling in the CA name, prompt when generating the key: The CSP is not configured correctly or the installation is incomplete.Cause: The possible cause for CS service (Crysptographic services) is not started.PS: The service relies on the RPC service, but the RPC service will have two, one is RPC, the other is RPC (Locator), and my second one is not started. After startup, the installation continues.2. Prompt when generating key: You do not ha

In the previous article, "CSP: Using CryptoAPI to decode X509 certificate content," describes how to use CryptoAPI to decode the certificate file to get the pccert_context method of the certificate context handle. Let's go on to get the desired certificate entry through the certificate context handle. This article first describes how to get the base entry for a certificate, and later an article explains how to obtain an extension of the certificate.Th

Swift adopts safe programming patterns and adds modern features to make programming easier, more flex

Why is swift so popular ?, Swift fire? First of all, swift is very popular. It ranks 16 in the month when it comes out. Why is it so hot? Is it because of the Apple brand? Or other reasons? As a code farmer (working for more than 15 years), I will talk about my personal opinions. There are many excellent PC-side development languages: JavaScript, Python, and Ruby
