XML-DSIG中的URI和摘要计算

时间：2015-01-19 09:49:28

标签： xml digest xml-dsig

我正在分析XML-DSIG文件，以便了解如何编写生成XML-DSIGnatures的软件代码。我有这个麻烦，迫切需要帮助...... 我试图从signatures0.xml（在此位之后引用）中理解这一点：

<Reference Type="http://uri.etsi.org/01903#SignedProperties" URI="#SignedPropertiesElem_0" xmlns="http://www.w3.org/2000/09/xmldsig#">

据我所知，第一个引用位指的是同一文件中的 SignedPropertiesElem_0 元素。我正在尝试确切地确定它所引用的内容 - 应该选择哪些代码并稍后用于规范化然后计算摘要值。是这样的：

<SignedProperties Id="SignedPropertiesElem_0">

或其他一些部分？

我尝试了第一个，然后让它通过StylusStudio规范化或http://www.soapclient.com/xmlcanon.html（两者似乎都返回相同的结果），结果如下：

                    </SigningCertificate>
                    <SignaturePolicyIdentifier>
                        <SignaturePolicyImplied></SignaturePolicyImplied>
                    </SignaturePolicyIdentifier>
                </SignedSignatureProperties>
            </SignedProperties>

然后使用这些工具计算摘要值：     http://www.webutils.pl/index.php?idx=sha1     hash.online-convert.com/sha256-generator     www.freeformatter.com/message-digest.html#ad-output

它们都返回相同的结果，但结果与xml文件中的结果不同： kOlNXyBs6oSP9hbh + 4niZMNQ9OsOCzYhkSYYG4YdHQU =

我做错了什么？我应该将xml文档的哪一部分复制并粘贴到规范化器中，然后复制到摘要计算器中？我花了几天时间尝试不同的事情，寻找答案而没有得到任何东西......我确信我错过了一些东西，因此我在寻求你的帮助。

我发现结果应该是：

<SignedProperties Id="SignedPropertiesElem_0">
                <SignedSignatureProperties>
                    <SigningTime>2014-08-21T06:09:55Z</SigningTime>
                    <SigningCertificate>
                        <Cert>
                            <CertDigest>
                                <DigestMethod Algorithm="http://www.w3.org/2001/04/xmlenc#sha256" xmlns="http://www.w3.org/2000/09/xmldsig#"/>
                                <DigestValue xmlns="http://www.w3.org/2000/09/xmldsig#">JQ0kZvd0mtXQPA/RTuYV9iuc346tznvN9MoAd/0jNyM=</DigestValue>
                            </CertDigest>
                            <IssuerSerial>
                                <X509IssuerName xmlns="http://www.w3.org/2000/09/xmldsig#">CN=Nacionalinis sertifikavimo centras (IssuingCA-B),OU=Nacionalinis sertifikavimo centras (NSC),O=Gyventoju registro tarnyba prie LR VRM - i.k. 188756767,C=LT</X509IssuerName>
                                <X509SerialNumber xmlns="http://www.w3.org/2000/09/xmldsig#">1315010063538360283821765366094690</X509SerialNumber>
                            </IssuerSerial>
                        </Cert>
                    </SigningCertificate>
                    <SignaturePolicyIdentifier>
                        <SignaturePolicyImplied/>
                    </SignaturePolicyIdentifier>
                </SignedSignatureProperties>
            </SignedProperties>

在规范化之后我无法获得正确的摘要值的原因是因为软件没有包含所有适用的命名空间声明，并且它也应该声明xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"。

Web哈希计算器的问题是在Windows中复制和粘贴文本时，LF换行符被CR + LF取代。
