Question

我正在生成XML Xades签名。我需要在TAG签名中添加名称空间http://uri.etsi.org/01903/v1.3.2#。

如果我在签署文档后添加此TAG，则会收到无效的签名错误。

我之前不知道如何添加它，因为签名后我只有TAG签名。

这是添加命名空间的代码

void addNamespace(doc)
{

    NodeList nl = doc.getElementsByTagNameNS(XMLSignature.XMLNS, "Signature");

    Node a = nl.item(0);

    Element sig = (Element)a;

sig.setAttributeNS("http://www.w3.org/2000/xmlns/","xmlns:etsi","http://uri.etsi.org/01903/v1.3.2#");

}

签名代码：

signContext = new DOMSignContext(pk, parentElement);
signContext.putNamespacePrefix("http://uri.etsi.org/01903/v1.3.2#","etsi");
XMLSignature signature;
signature.sign(signContext);
addNamespace(doc);

XML：

我需要该命名空间将在TAG签名中而不是TAG对象

Answer 1

命名空间用于计算哈希值。规范化应将它们添加到文档中（另外按字母顺序）。将名称空间添加到签名文档显然会改变其哈希值

添加名称空间时无效的XML签名
