PHP対称暗号化アルゴリズム|Mcrypt.class.php
keyは定義の定数
メッソッド:
Mcrypt::encrypt();
Mcrypt::decrypt();
サンプルコード:
defined('ROOT') or exit('Access Denied'); class Mcrypt{ //暗号化 public static function encrypt($code){ return base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, md5(KEY), $code, MCRYPT_MODE_ECB, mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB), MCRYPT_RAND))); } //解読 public static function decrypt($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)); } }
