Yii provides convenient helper functions that allow you to encrypt and decrypt data using a security key. Data is transmitted through an encryption function so that only someone with the security key can decrypt it. For example, we need to store some information in our database, but we need to ensure that only people with the security key can see it (even if the application's database is leaked)
$data is the content you want to encrypt ,
$secretKey is the password you set yourself,
$encryptedData = Yii::$app->getSecurity()->encryptByPassword($data, $secretKey);
Later, when the user needs to read the data:
$encryptedData 是你要解密的內(nèi)容 $secretKey 是你自己設置加密時的密碼 $data = Yii::$app->getSecurity()->decryptByPassword($encryptedData, $secretKey);
But Encrypt the string, and the encrypted string is a string of garbled characters (it does look like garbled characters, and the specifics need to be verified), which is not conducive to our next operation.
We can use base64 to process the encrypted string. The processed string is composed of letters and numbers
Application example:
//Invitation registration
$id = Yii::$app->user->getId();//獲取登錄用戶id //加密(此處加密密碼設為空) $uid = base64_encode(yii::$app->security->encryptByPassword($id,'')); //解密 $iss=yii::$app->security->decryptByPassword(base64_decode($uid),'');

Title: Data Encryption and Decryption Using ReactQuery and Database Introduction: This article will introduce how to use ReactQuery and database for data encryption and decryption. We will use ReactQuery as the data management library and combine it with the database to perform data encryption and decryption operations. By combining these two technologies, we can securely store and transmit sensitive data, and perform encryption and decryption operations when needed to ensure data security. Text: 1. ReactQue

Encrypting and decrypting sensitive data using Yii framework middleware Introduction: In modern Internet applications, privacy and data security are very important issues. To ensure that users' sensitive data is not accessible to unauthorized visitors, we need to encrypt this data. The Yii framework provides us with a simple and effective way to implement the functions of encrypting and decrypting sensitive data. In this article, we’ll cover how to achieve this using the Yii framework’s middleware. Introduction to Yii framework Yii framework is a high-performance PHP framework.

As WeChat mini programs become more popular in the mobile application market, their development has also received more and more attention. In small programs, PHP, as a commonly used back-end language, is often used to handle the encryption and decryption of sensitive data. This article will introduce how to use PHP to implement encryption and decryption in WeChat applet. 1. What are encryption and decryption? Encryption is the conversion of sensitive data into an unreadable form to ensure that the data is not stolen or tampered with during transmission. Decryption is the restoration of encrypted data to original data. In small programs, encryption and decryption usually include
