问题
I need to sign a XML file with a private RSA key to be verified with my C# application. When I sign the xml with my C# application, this is the final output:
<Signature xmlns="http://www.w3.org/2000/09/xmldsig#">
<SignedInfo>
<CanonicalizationMethod Algorithm="http://www.w3.org/TR/2001/REC-xml-c14n-20010315" />
<SignatureMethod Algorithm="http://www.w3.org/2000/09/xmldsig#rsa-sha1" />
<Reference URI="">
<Transforms>
<Transform Algorithm="http://www.w3.org/2000/09/xmldsig#enveloped-signature" />
</Transforms>
<DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1" />
<DigestValue>VIRRzqwb20aCSXrRTX1Y5vW//IA=</DigestValue>
</Reference>
</SignedInfo>
<SignatureValue>mS3JQ/KmyXCayLly4hHRXKM51jPy230B3h4ngjzOhq0xR/7BRDQP2wfp7ugVcL5kMWaV+pBHbJgdvvu8OrzyxCUQ+R7RYqWpEBYJHUARov0Pws7oFybFpmzRnwhg2gPaPEzcVpK4VL4G1iM07XgmoSKM8Id0fRQ1lD+4BEcAxNY=</SignatureValue>
</Signature>
Signing in C#:
public static void SignXmlDocument(RSA key, XmlDocument doc)
{
var sxml = new SignedXml(doc);
sxml.SigningKey = key;
sxml.SignedInfo.CanonicalizationMethod = SignedXml.XmlDsigCanonicalizationUrl;
var r = new Reference("");
r.AddTransform(new XmlDsigEnvelopedSignatureTransform(false));
sxml.AddReference(r);
sxml.ComputeSignature();
var sig = sxml.GetXml();
doc.DocumentElement.AppendChild(sig);
}
How can I make the same in PHP?
回答1:
You can use XMLDsig
Install the library and register the paths in your autoloader. If you use composer both steps are automatic.
require_once __DIR__ . '/vendor/autoload.php';
$xmlDocument = new DOMDocument();
$xmlDocument..... // define the contents to sign
$xmlTool = new FR3D\XmlDSig\Adapter\XmlseclibsAdapter();
$xmlTool->setPrivateKey(file_get_contents('<path to your private key>/private.pem');
$xmlTool->addTransform(FR3D\XmlDSig\Adapter\XmlseclibsAdapter::ENVELOPED);
$xmlTool->sign($xmlDocument);
Now $xmlDocument
has the <signature>
element at the end.
