问题描述
谁能帮助我将Sagepay v3.00 AES / CBC / PKCS＃5算法（加密）合并到以下文件中。我真的很难理解如何包括在内，以便将客户数据加密为新标准，然后在返回时解密。将Sagepay Form与非常老版本的cs-cart一起使用，尽管已成功地将其从2.22版本升级到2.23，但Sagepay将从7月撤回所有支持。
Can anyone help me incorporate the Sagepay v3.00 AES/CBC/PKCS#5 algorithm (encryption) into the following file. I'm really struggling to understand how to include so that customer data is encrypted to the new standard and then decrypted on the way back. Using Sagepay Form with a very old version of cs-cart, though have successfully managed to upgrade from version 2.22 to 2.23, but Sagepay are pulling all support from July.
否确保此脚本有多少与加密有关：
Not sure how much of this script is relevant to the encryption:
<?php

// Get the password

$processor_data = fn_get_payment_method_data($payment_id);
$result = "&".simpleXor(base64Decode($_REQUEST['crypt']), $processor_data["params"]["password"])."&";
preg_match("/Status=(.+)&/U", $result, $a);

推荐答案
/*First build your data. */
$data = 'variableA='.$this->variableA;
$data .= '&variableB='.$this->variableB;
...
$data .= '&variableZ='.$this->variableZ;
/** Encript data */
$dataEncrip = $this->encData($data);
/** function to Encrypt *//
public function encData($data){
$data = $this->pkcs5_pad( $data, 16);
$dataEnc = "@".bin2hex( mcrypt_encrypt( MCRYPT_RIJNDAEL_128,
$this->passwordToEncript,
$data,
MCRYPT_MODE_CBC,
$this->getPasswordToEncrypt()));
return $dataEnc;
}
/** Pkcs5_pad */
public function pkcs5_pad( $data, $blocksize ){
$pad = $blocksize - (strlen( $data ) % $blocksize);
return $data . str_repeat( chr( $pad ), $pad );
}
