key 是之前定义的常量
mcrypt::encrypt();
mcrypt::decrypt();
defined('root') or exit('access denied'); class mcrypt{ public static function encrypt($code){ return base64_encode(mcrypt_encrypt(mcrypt_rijndael_256, md5(key), $code, mcrypt_mode_ecb, mcrypt_create_iv(mcrypt_get_iv_size(mcrypt_rijndael_256, mcrypt_mode_ecb), mcrypt_rand))); } public static function decrypt($code){ return mcrypt_decrypt(mcrypt_rijndael_256, md5(key), base64_decode($code), mcrypt_mode_ecb, mcrypt_create_iv(mcrypt_get_iv_size(mcrypt_rijndael_256, mcrypt_mode_ecb), mcrypt_rand)); } }
