将对象标签添加到 C# 中的 X509Certificate2

编程问答 2022-05-22

问题描述

我在将对象标签添加到我的签名时遇到问题，因为我们的参与者需要它在签名的 XML 的签名中。 我需要在我的签名中添加下面的 Object 标签：

<ds:Object>
    <xades:QualifyingProperties xmlns:xades="http://uri.etsi.org/01903/v1.3.2#">
        <xades:SignedProperties Id="_aba0ee84-5f37-499e-a8e8-caa7f398341c-signedprops">
            <xades:SignedSignatureProperties>
                <xades:SigningTime>2019-02-15T21:09:10+13:00</xades:SigningTime>
            </xades:SignedSignatureProperties>
        </xades:SignedProperties>
    </xades:QualifyingProperties>
</ds:Object>

我目前的签名看起来像：

    <MyElement xmlns="samples">Example text to be signed.
    <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/2001/04/xmldsig-more#rsa-sha256"/>
            <Reference URI="">
                <Transforms>
                    <Transform Algorithm="http://www.w3.org/2000/09/xmldsig#enveloped-signature"/>
                </Transforms>
                <DigestMethod Algorithm="http://www.w3.org/2001/04/xmlenc#sha256"/>
                <DigestValue>Kglqb8fjGmMi2n4W8qXldBIY7VBi0xbNn+dZml7H3xw=</DigestValue>
            </Reference>
        </SignedInfo>
        <SignatureValue>Iz5LOjZGefMHvIYs/cr1Vmrg/9gXPDGpJetBEx+k/yzHVAdJf18P2/udFkeOoVMCpVUnNn+H4eVihD2idqg7SMosZeFA4LCQC2/Wn7GCE6k+y0mivCtFZTaXu0yUbwDGWDBvvqMUT87uaRx4o61cm7V3DH8wOUJ05mKtoVFpG20=</SignatureValue>
    </Signature>
</MyElement>

我需要的最终签名应该如下所示：

 <ds:Signature xmlns:ds="http://www.w3.org/2000/09/xmldsig#">
    <ds:SignedInfo>
        <ds:CanonicalizationMethod Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#"/>
