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));
	}

}
