, but the string can only be decrypted by the application using the Microsoft.Owin.Security.OAuth component (excluding the implementation of the referenced source code). and also to ensure that the encryption key is the same decryption. But OAuth is often used in distributed scenarios, and even uses different languages to write different applications and services. In this way, the above token can not meet the needs of the implementation.It is therefore necessary to use JWT Bearer

foreach statement, a redundant castclass instruction is also required to guarantee the correctness of the type conversion of the enumerated values. The following are references: Using System.Collections; public class Tokens:ienumerable { ... Tokens F = new tokens (...); foreach (string item in F) { Console.WriteLine (item); } ... } The simple code above is automatically converted to The followi

connection between the front-end identity management software and the back-end application server does not pass through Secure Sockets Layer (SSL), which means that the user certificate is passed as non-encrypted plain text. Even if the connection is secure, the backend server will use the certificate from the front-end access Manager to authenticate the authenticated user again unless it can verify that the request came from a trusted source, the authenticated user. This situation req

Label: AR for SP Div BS as Har technical programming A string is divided into multiple sub-characters according to a specific character. In general programming languages, a built-in method is provided to implement this function. In batch processing, you can use the for command. The command format is as follows: for /f "tokens=x,y,m-n delims=chars" %%a in ("str") do cmd Here, tokens gets the number of col

in the corresponding location of token_t * tokens. 1 // parameter 1: string of the command 2 // parameter 2: After parsing the command, store the struct array of each field of the command 3 // parameter 3: maximum number of command fields 4/* 5 * tokens [0] => After parsing the text command, return to the process_command function. We can see the familiar command. Yes, next, in the multi-branch judgment of

Select function The function of the Tokensize function has been introduced, and a tokens array has been generated, and we have introduced the composition of it, and the following is how to deal with this tokens array. The connection relationship between DOM elements is about > + ~ Several, including spaces, while the tokens array is a type that has tags, attr, a

change the data, the CSRF attack cannot resolve the results returned by the server, without protection.Several strategies of current defensive CSRFThere are three main strategies for defending against CSRF attacks in the industry: Validating HTTP Referer fields, adding tokens to the request address and validating it, customizing properties in the HTTP header, and validating. These three strategies are described in detail below.Validating HTTP Referer

understanding of the role of/F, execute the following two commands for comparison: For/F % I in (a.txt) Do echo % I // This will display the content in a.txt, because/F will read a.txt. For % I in (a.txt) Do echo % I // This only displays the.txt name and does not read the content. Through the above learning, we found that for/F will use each row as an element by default, but what if we want to break down each row into smaller content? Don't worry, the for command also provides us with more d

These features require the application to know that the requests it receives come from the same user. The

ARP spoofing is achieved by forging IP addresses and MAC addresses, which can generate a large amount of ARP traffic in the network to block the network, attackers can change the IP-MAC entries in the ARP cache of the target host as long as they continuously generate forged ARP response packets, resulting in network interruptions or man-in-the-middle attacks. This article introduces four methods to defend against ARP attacks by using self-made batch processing files. 1. Compile the following sta

line. The server can write the session ID itself into the browser's cookie.Token-based authenticationToken-based authentication mainly refers to the JSON Web token authentication, or JWT authentication.It mainly consists of the following steps : The user enters a user name and password to send to the server. The server authenticates the user name and password, and succeeds returns a token (which can be considered a long string) to the browser. Each subsequent request, the brows

. we can call it the back-end of the compiler. A language is called a compilation language. it is generally because there is a translation process before the execution of the program. The key point is that there is a completely different form of equivalent program generation. PHP is called an interpreted language because no such program is generated. it generates intermediate code Opcode, which is only an internal data structure of PHP.II. PHP code execution process For example, we can write a s
