Article Introduction：Sharing of PHP encryption and decryption functions, one is Discuz!'s authcode encryption function (with detailed breakdown), and the other is the encrypt() function. PHP needs to be used to encrypt specific information, that is, an encrypted string is generated through the encryption algorithm. This encrypted string can be decrypted through the decryption algorithm to facilitate the program to process the decrypted information.

Article Introduction：Encryption in cryptocurrency refers to the use of encryption technology to protect the security of transactions and information. Plain text is converted into cipher text through encryption algorithms, which can only be read by the owner of the key. Cryptocurrencies make extensive use of cryptographic technologies, including hash functions, digital signatures, asymmetric encryption, and blockchain, to ensure transaction security, privacy, immutability, and transparency.

Article Introduction：As the PHP version is upgraded, some functions have been abandoned, such as encryption and decryption functions. Before PHP7.1, decryption and encryption were implemented through mcrypt_decrypt() and mcrypt_encrypt(), and after PHP7.1 through openssl_decrypt() and openssl_encrypt(). Decryption and encryption. Here, through the encapsulation class, two implementation methods are used to implement two methods of encryption and decryption steps: the original data is returned during decryption (array-->encryption-->encrypted string--&g...

Article Introduction：There are a variety of front-end encryption algorithms that can be used for data encryption and decryption. This is a simple database-level data encryption and decryption solution. Taking the MySQL database as an example, it has built-in corresponding encryption function (AES_ENCRYPT()) and decryption function (AES_DECRYPT()).
