All email messages sent to Sandbox accounts can be accessed only in the Email section of Developer Central. Sandbox account emails are never sent to an actual email address. Even if you use a real email address to create a Sandbox account, you will never receive an actual email from the Sandbox. This is meant to reduce confusion, so that you never mistake your real PayPal account emails with your Sandbox account emails. All Sandbox email is accessed by clicking the Email tab in Developer Central. A sample Developer Central account with Sandbox email messages is shown in Figure 2-3.

Generic HMAC Function function hmac ($key, $data) { $b = 64; // byte length if (strlen($key) > $b) { $key = pack("H*",sha1($key)); } $key = str_pad($key, $b, chr(0x00)); $ipad = str_pad('', $b, chr(0x36)); $opad = str_pad('', $b, chr(0x5c)); $k_ipad = $key ^ $ipad ; $k_opad = $key ^ $opad; return sha1($k_opad } The process for generating the signature is similar to generating the digest A different node set is used, and HMAC SHA1 is being performed; however, in this example, the element SignedInfo is being converted into its canonical form, and the signing algorithm is applied The resulting value is then set as the content for the SignatureValue element and appended as a child to the Signature element For example: $dom = new DOMDocument(); $copyInfo = $dom->importNode($signedInfo, TRUE); $dom->appendChild($copyInfo); /* Following works only with PHP 51 and above LIBXML_NOEMPTYTAG used to create start and end tags for empty elements.

Document element $copyInfo passed to dump the node, which does not generate an XML declaration output pack("H*",sha1($k_ipad $data)));.

In this chapter, you have learned how to design your application and go from the requirement gathering and specification through design to the actual implementation. You learned how to use the Django framework for rapid web application development. Always start with the requirements specification. This will act as a reference point and simplify testing. It also helps managing user expectations. Design the data model first and make sure the design is in line with requirements. Decouple the application from the project (or web site), so it can be reused multiple times.

*/ $canonical = $dom->saveXML($copyInfo, LIBXML_NOEMPTYTAG); /* Calculate HMAC SHA1 */ $hmac = hmac($key,$canonical); print $hmac."\n"; $bhmac = base64_encode(pack("H*", $hmac)); /* Handle whitespaces for presentation layout */ $addPrev = NULL; $addPost = NULL; if ($Object->previousSibling->nodeType == XML_TEXT_NODE) { $addPrev = clone $Object->previousSibling; } if ($Object->nextSibling->nodeType == XML_TEXT_NODE) { $addPost = clone $Object->nextSibling; } /* END Handle whitespaces for presentation layout */ /* Create and append the SignatureValue element as child of Signature element insertBefore used with whitespacing to generate output in Listing 12-2. */ $sigValue = $doc->createElementNS("http://www.w3.org/2000/09/xmldsig#", "SignatureValue", $bhmac); if ($addPrev) { $Object->parentNode->insertBefore($sigValue, $Object->previousSibling); } else { $Object->parentNode->insertBefore($sigValue, $Object); } /* Following is done in example only to add proper whitespacing */ if ($addPost) { $Object->parentNode->insertBefore($addPrev, $sigValue); } print $doc->saveXML(); The resulting document should look exactly like the document in Listing 12-2, down to the same whitespaces used.
