The steps for validating the signature are also similar to creating the signature, though the tree is not modified. Again, the algorithm specified by the SignatureMethod element is applied to the canonical form of the SignedInfo element. The canonical form is generated using the method specified by the CanonicalizationMethod element. The same rules apply for verifying the value as those from verifying a reference. In the following example, the binary values, rather than the Base64-encoded values, are compared to determine the authenticity of the message and signer: /* Retrieve Value for SignatureValue element */ $query = 'string(//*[local-name()="SignatureValue" '. 'and namespace-uri()="http://www.w3.org/2000/09/xmldsig#"])'; $signature = base64_decode($xPath->evaluate($query)); /* Generate canonical form of SignedInfo element*/ $signedInfo = $xPath->query("//*[local-name() = 'SignedInfo']")->item(0); $dom = new DOMDocument(); $copyInfo = $dom->importNode($signedInfo, TRUE); $dom->appendChild($copyInfo); /* Following works only with PHP 5.1 and above LIBXML_NOEMPTYTAG used to create start and end tags for empty elements document element $copyInfo passed dump the node which does not generate an XML declaration output */ $canonical = $dom->saveXML($copyInfo, LIBXML_NOEMPTYTAG); $key = "secret"; $hmac = hmac($key,$canonical); $calc_signature = pack("H*", $hmac); if ($signature != $calc_signature) { print "Signature Authentication Failed"; } else { print "Signature Authentication Success!"; }

I mentioned support for DHCP as a requirement in the previous chapter, but what do we really want from it Let s take a look at how DHCP is used in a typical organization. I will assume the ISC DHCP service, which is widely available with most Linux distributions. When assigning addresses on a subnet, we have the following options: Assign the IP addresses statically, in which case we configure each device with its own IP address. Assign the IP addresses dynamically, depending on a set of rules using the DHCP service.

chapter are only a small subset of what can be performed using XML signatures. The steps are meant as an introduction to get you started using digital signatures. Signatures can become quite complex working with multiple sets of data, data residing in different locations, different types of data, and different algorithms. The material presented here is intended only as a starting point, and you should refer to the specifications to work with more advanced and complex XML signatures.

Ti p Before proceeding with this chapter, you may want to install the ISC DHCP server package. You can do that by using the package manager available with your Linux distribution (on Red Hat Linux it can be done with the command yum install dhcp). Alternatively, you can download it from the official ISC DHCP website at http://www.isc.org/software/dhcp.

In many instances, an XML document can contain sensitive data. For example, an e-commerce system can collect customer and payment information and send that to a secure server for processing rather than storing the information on a public server. This type of scenario pertains more toward smaller businesses because they typically lack the resources to implement a large, secure environment and tend to host their e-commerce systems with a hosting provider. In this day and age, it is extremely unlikely for sensitive data to be left on these public servers. In some cases, online credit card processors are used, leaving the small business with the freedom of not having to deal with storing and managing this information. Some companies, however, still process credit card information internally. It is possible they also have a brick and mortar store and handle sales processing together. It is important to these companies to transmit the sensitive information from their public site to their more secure internal network. SSL is one possible method of handling this. The data is encrypted during transit. Though once received, the data is back to clear text. This may not be a desirable situation. This is a case where XML encryption may come in handy.

Your PayPal account has a status associated with it, and depending on the status of your account, you are or aren t able to perform certain actions. The various PayPal account statuses are described in the sections that follow.

XML signatures only get you so far. They provide the mechanisms to verify the integrity and authenticity of the data, but the data is still, in most cases, in plain text. The W3C has defined some specifications in order for systems to implement a common format to perform XML encryption. The XML Encryption Syntax and Processing specification (http://www.w3.org/ TR/xmlenc-core/) specifies a process for encrypting data and representing the result in XML. The XML Encryption Requirements specification (http://www.w3.org/TR/xml-encryption-req/) specifies the requirements for implementing XML encryption.

You can use XML encryption to sign virtually any type of data. This includes both XML and non-XML-based data. Just like XML signatures, the data can even be located outside the XML encryption document. This section will explain the granularity available using XML encryption. This means examining the different pieces and types of data that could be encrypted and their relation to the XML encryption document. Consider the example of an order from an e-commerce site explained earlier. If using XML format to describe the order, it may appear in the following form, which is a stripped-down version of some payment information:

Let s quickly recap what the DHCP can do and how it is configured. The ISC DHCP allows us to define very complicated sets of rules. The simplest set would contain no rule at all, in which case any
