XmlDSig .Net specific information

.Net Specific information to performs XML signing and XML signature verification using GeneXus XmlSignature Module

• System.Security.Cryptography.Xml does not qualify XML. This means Signatures created with .Net and Net Core generators will have the below format:

<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" />
                <Transform Algorithm="http://www.w3.org/TR/2001/REC-xml-c14n-20010315" />
            </Transforms>
            <DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1" />
            <DigestValue>Oy8OX..Ug8ho=</DigestValue>
        </Reference>
    </SignedInfo>
   <SignatureValue>DTl51DmjF..v8z1bl5S+9wyWE3PuB7kk=</SignatureValue>
</Signature>

• Also, elements without contents (example; Transform element) will close the XML tag on the same tag (<Transform Algorithm="http://www.w3.org/2000/09/xmldsig#enveloped-signature" />). This is the equivalent on XML to <Transform Algorithm="http://www.w3.org/2000/09/xmldsig#enveloped-signature" ></Transform>, which means it is compatible with Java xmlsec implementation.
• The use of an xPath is disallowed by default for .Net Framework applications. For more information, read link1, link2.
• The use of an xPath is disallowed by default for .Net Core System.Security.Cryptography.Xml library for checksignature.
