php - 尝试在 PHP 中使用 x.509 证书对 SOAP 调用进行数字签名

Question

我正在与客户合作，尝试使用 PHP 发送和接收 soap 调用。他们设置了 ws-security，并使用 x.509 证书进行身份验证。我已经能够使用 SoapUI 使其正常工作，但我无法在 PHP 中使用它。

我遇到的问题是，他们不使用标准的二进制安全 token 或用户名/密码组合。他们改为在安全 token 引用中签署 XML 文件。

我一直在尝试使用 Rob Richards 的库来生成散列，它似乎包含了代码来完成我正在尝试做的事情，但我一直没有成功实现它。 (https://github.com/robrichards/wse-php)

这是我们应该得到的:

以及使这一切正常工作的 PHP 类:

<?php
class MySoap extends SoapClient {
    public function __doRequest($request, $location, $saction, $version) {
        $doc = new DOMDocument('1.0');
        $doc->loadXML($request);

        $objWSSE = new WSSESoap($doc);

        /* add Timestamp with no expiration timestamp */
        $objWSSE->addTimestamp();

        /* create new XMLSec Key using AES256_CBC and type is private key */
        $objKey = new XMLSecurityKey(XMLSecurityKey::RSA_SHA1, array('type' => 'public'));

        /* load the private key from file - last arg is bool if key in file (true) or is string (false) */
        $objKey->loadKey("c:\\xampp\htdocs\\XMLSoapApp\\cert1.pem", $isFile=true, true);

        /* Sign the message - also signs appropiate WS-Security items */
        $options = array("insertBefore" => true);

        $objWSSE->signSoapDoc($objKey, $options);

        /* Add certificate (BinarySecurityToken) to the message */ 
        $token = $objWSSE->addBinaryToken(file_get_contents(combine_key));

        /* Attach pointer to Signature */
        $objWSSE->attachTokentoSig($token);
        return $doc->saveXML();
    }
}

必须有一种方法可以轻松做到这一点，但我似乎错过了它。以前有人这样做过吗？

Answer 1

据我所知，您使用了错误的 key 类型:它应该是 XMLSecurityKey::DSA_SHA1，但您使用的是 XMLSecurityKey::RSA_SHA1。顺便说一句，lib 不支持第一个。但是还是可以解决的。您可以在下面找到我用来测试它的代码。

1. 生成 key (great hint):

openssl dsa -in dsakey.private
openssl req -x509 -new -days 3650 -key dsakey.private -out dsakey.cert
openssl dsa -in dsakey.private -pubout -out dsakey.pub

1. 修补库:

在 vendor/robrichards/xmlseclibs/src/XMLSecurityKey.php 第 216 行添加以下 case block :

case (self::DSA_SHA1):
  $this->cryptParams['library'] = 'openssl';
  $this->cryptParams['method']  = 'http://www.w3.org/2000/09/xmldsig#dsa-sha1';
  $this->cryptParams['padding'] = OPENSSL_PKCS1_PADDING;
  $this->cryptParams['digest']  = OPENSSL_ALGO_SHA1;
  if (is_array($params) && ! empty($params['type'])) {
    if ($params['type'] == 'public' || $params['type'] == 'private') {
      $this->cryptParams['type'] = $params['type'];
      break;
    }
  }
  throw new Exception('Certificate "type" (private/public) must be passed via parameters');
break;

1. 运行签名功能:

use RobRichards\WsePhp\WSSESoap;
use RobRichards\XMLSecLibs\XMLSecurityKey;

$doc = new DOMDocument('1.0');
$doc->loadXML(file_get_contents('/request.xml'));

$objWSSE = new WSSESoap($doc);
$objWSSE->addTimestamp();

$objKey = new XMLSecurityKey(XMLSecurityKey::DSA_SHA1, ['type' => 'private']);

$objKey->loadKey('/dsakey.private', true);
$options = ['insertBefore' => true];
$objWSSE->signSoapDoc($objKey, $options);

$token = $objWSSE->addBinaryToken(file_get_contents('/dsakey.cret'));
$objWSSE->attachTokentoSig($token);

echo $doc->saveXML();

1. 下面是我通过上面的代码片段获得的 XML 代码:
