PHP如何使用AES加密和解密

标签:color 偏移量 mcrypt his ons openssl扩展 span fun 如何使用 AES加密在php5的版本中使用的mcrypt_decrypt 函数,该函数已经在php7.1后弃用了,取而代之的是openssl的openssl_encrypt和openssl_decrypt,并且代码也非常精简,下面是示例代码: 注意:要使用openssl相关函数必须要开启openssl扩展,否则程序报错 链接:https://www.php.cn/php-weizijiaocheng-437570.html(文章没有提示要开启openssl,不知道的人会踩坑报错) PHP如何使用AES加密和解密 标签:color 偏移量 mcrypt his ons openssl扩展 span fun 如何使用 原文地址:https://www.cnblogs.com/clubs/p/12009414.html 1 php
