php mcrypt等效于Windows服务器上的sagepay [英] php mcrypt equivalent for sagepay on a windows server

问题描述

直到最近，我们公司才开始使用vbscript，当我们开始变为PHP时。在尝试将SagePay表单套件整合到我们的一个项目中时，我遇到了这个障碍。

我们在Windows 2008服务器上，无法更改。服务器不包含mcrypt库，由于它是共享平台，我们的服务器主机将不会安装它。

有问题的行来自SagePay表单套件，您可以使用SagePay支付费用。希望你们中的一些人会熟悉这些。

有问题的是：

 code> // **使用PHP的MCRYPT模块执行加密
 $ strCrypt = mcrypt_encrypt（MCRYPT_RIJNDAEL_128，$ strEncryptionPassword，$ strIn，MCRYPT_MODE_CBC，$ strIV）; 
  

这是更大的加密函数的一部分，如下所示：

  // ** Wrapper函数根据strEncryptionType设置加密编码** 
函数encryptAndEncode（$ strIn）{
 
全局$ strEncryptionType 
，$ strEncryptionPassword; 
 
 if（$ strEncryptionType ==XOR）
 {
 // **使用Base64编码的XOR加密** 
返回base64Encode（simpleXor（$ strIn， $ strEncryptionPassword））; 
} 
 else 
 {
 // ** AES加密，CBC封锁PKCS5填充然后HEX编码 -  DEFAULT ** 
 
 // **使用初始化向量（IV）从$ strEncryptionPassword 
 $ strIV = $ strEncryptionPassword; 
 
 // **添加PKCS5填充到待被文本的
 $ strIn = addPKCS5Padding（$ strIn）; 
 
 // **使用PHP的MCRYPT模块执行加密
 $ strCrypt = mcrypt_encrypt（MCRYPT_RIJNDAEL_128，$ strEncryptionPassword，$ strIn，MCRYPT_MODE_CBC，$ strIV）; 
 
 // **执行十六进制编码并返回
返回@。 BIN2HEX（$ strCrypt）; 
} 
} 
  

有谁知道我可能能够绕过这个问题，还是我可以在其中实现的等效的库？任何指针，提示或点在正确的方向将是非常感谢。

编辑好的，所以经过研究更多，据了解，我只需要一个128位AES加密功能，而不使用mcrypt。

解决方案

有很多替代方案，缺乏您的提供者的支持/意愿将是粘性点。

如果您是自己的VPS /能够下一条新路线。我建议OpenSSL; http://www.openssl.org/ - 由于您在Windows上可能会查看 http://slproweb.com/products/Win32OpenSSL.html

您是否通过 phpinfo（）查看可用的内容？

还有PCrypt ;

Our company primarily used vbscript until fairly recently, when we started changing to PHP. Upon trying to integrate a SagePay form kit into one of our projects I came across this obstacle.

We are on a windows 2008 server, and this cannot be changed. The server does not contain the mcrypt library and our server host will not install it due to it being a shared platform.

The problematic line comes from a SagePay form kit that you use to pay for things with SagePay. Hopefully some of you will be familiar with these.

The line in question is:

//** perform encryption with PHP's MCRYPT module
$strCrypt = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $strEncryptionPassword, $strIn, MCRYPT_MODE_CBC, $strIV);

This is part of a larger encrytion function as follows:

//** Wrapper function do encrypt an encode based on strEncryptionType setting **
function encryptAndEncode($strIn) {

    global $strEncryptionType
          ,$strEncryptionPassword;

    if ($strEncryptionType=="XOR") 
    {
        //** XOR encryption with Base64 encoding **
        return base64Encode(simpleXor($strIn,$strEncryptionPassword));
    } 
    else 
    {
        //** AES encryption, CBC blocking with PKCS5 padding then HEX encoding - DEFAULT **

        //** use initialization vector (IV) set from $strEncryptionPassword
        $strIV = $strEncryptionPassword;

        //** add PKCS5 padding to the text to be encypted
        $strIn = addPKCS5Padding($strIn);

        //** perform encryption with PHP's MCRYPT module
        $strCrypt = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $strEncryptionPassword, $strIn, MCRYPT_MODE_CBC, $strIV);

        //** perform hex encoding and return
        return "@" . bin2hex($strCrypt);
    }
}

Does anyone know how I may possibly be able to bypass this problem, or an equivalent library that I may be able to implement in its place? Any pointers, tips or points in the correct direction would be most appreciated.

EDIT Ok so after researching it more, as I understand it, I just need a 128 bit AES Encryption function, without the use of mcrypt.

解决方案

There are plenty of alternatives, the lack of support/willingness from your hosing provider would be the sticky point.

If you were on your own VPS/In a position to go down a new route. I'd recommend OpenSSL; http://www.openssl.org/ - Since you're on windows maybe check out http://slproweb.com/products/Win32OpenSSL.html

Have you checked through phpinfo()to see what is available to you?

There is also PCrypt; http://www.phpclasses.org/package/1610-PHP-Symetric-encryption-of-data-using-only-PHP-code.html
