php aes encryption and decryption
加密的时候先aes加密,在进行base64加密
<?php /** * 利用mcrypt做AES加密解密 */ class Aes { /** * 算法,另外还有192和256两种长度 */ const CIPHER = MCRYPT_RIJNDAEL_128; /** * 模式 */ const MODE = MCRYPT_MODE_ECB; /** * 加密 * @param string $key 密钥 * @param string $str 需加密的字符串 * @return type */ public function encode( $key, $str ){ $iv = mcrypt_create_iv(mcrypt_get_iv_size(self::CIPHER,self::MODE),MCRYPT_RAND); return mcrypt_encrypt(self::CIPHER, $key, $str, self::MODE, $iv); } /** * 解密 * @param type $key * @param type $str * @return type */ public function decode( $key, $str ){ $iv = mcrypt_create_iv(mcrypt_get_iv_size(self::CIPHER,self::MODE),MCRYPT_RAND); return mcrypt_decrypt(self::CIPHER, $key, $str, self::MODE, $iv); } } ?>
The above introduces php aes encryption and decryption, including aspects of the content. I hope it will be helpful to friends who are interested in PHP tutorials.

The usage of return in C language is: 1. For functions whose return value type is void, you can use the return statement to end the execution of the function early; 2. For functions whose return value type is not void, the function of the return statement is to end the execution of the function. The result is returned to the caller; 3. End the execution of the function early. Inside the function, we can use the return statement to end the execution of the function early, even if the function does not return a value.

The reason for the error is NameResolutionError(self.host,self,e)frome, which is an exception type in the urllib3 library. The reason for this error is that DNS resolution failed, that is, the host name or IP address attempted to be resolved cannot be found. This may be caused by the entered URL address being incorrect or the DNS server being temporarily unavailable. How to solve this error There may be several ways to solve this error: Check whether the entered URL address is correct and make sure it is accessible Make sure the DNS server is available, you can try using the "ping" command on the command line to test whether the DNS server is available Try accessing the website using the IP address instead of the hostname if behind a proxy

Source code: publicclassReturnFinallyDemo{publicstaticvoidmain(String[]args){System.out.println(case1());}publicstaticintcase1(){intx;try{x=1;returnx;}finally{x=3;}}}#Output The output of the above code can simply conclude: return is executed before finally. Let's take a look at what happens at the bytecode level. The following intercepts part of the bytecode of the case1 method, and compares the source code to annotate the meaning of each instruction in

How to replace mcrypt with php: 1. Open the corresponding php file; 2. Find the original encryption and decryption code; 3. Use the "openssl_encrypt" and "openssl_decrypt" methods to replace it.

Before introducing the usage of self in Python, let’s first introduce the classes and instances in Python. We know that the most important concepts of object-oriented are classes and instances. Classes are abstract templates, such as abstract things like students. , can be represented by a Student class. Instances are specific "objects" created based on classes. Each object inherits the same methods from the class, but its data may be different. 1. Take the Student class as an example. In Python, the class is defined as follows: classStudent(object):pass(Object) indicates which class the class inherits from. The Object class is all

JavaScript functions provide two interfaces to interact with the outside world. The parameters serve as the entrance to receive external information; the return value serves as the outlet to feed back the operation results to the outside world. The following article will take you to understand the JavaScript function return value and briefly analyze the usage of the return statement. I hope it will be helpful to you!

Vue3.2 setup syntax sugar is a compile-time syntax sugar that uses the combined API in a single file component (SFC) to solve the cumbersome setup in Vue3.0. The declared variables, functions, and content introduced by import are exposed through return, so that they can be used in Vue3.0. Problems in use 1. There is no need to return declared variables, functions and content introduced by import during use. You can use syntactic sugar //import the content introduced import{getToday}from'./utils'//variable constmsg='Hello !'//function func

Python return value return usage is that when the function executes the return statement, execution will stop immediately and the specified value will be returned to the place where the function was called. Detailed usage: 1. Return a single value; 2. Return multiple values; 3. Return a null value; 4. End the execution of the function early.
