我正在尝试使用 python2 版本 o XAdes 和 XMLSIG 签署文档。我不想用 Xades-BES 标准签署所述文件。
我正在做的是以下
def get_signature(self, root, cert_file, xml_file):
roots = etree.parse(xml_file).getroot()
signature = xmlsig.template.create(c14n_method=xmlsig.constants.TransformInclC14N, sign_method=xmlsig.constants.TransformRsaSha256, name="EmitterPartySignatureId")
signature_id = self.iud
xmlsig.template.add_reference(signature, xmlsig.constants.TransformSha256, uri="#"+ signature_id,name="DataReferenceId")
ref = xmlsig.template.add_reference(signature, xmlsig.constants.TransformSha256, uri="#SignedPropertiesId", uri_type="http://uri.etsi.org/01903#SignedProperties")
xmlsig.template.add_transform(ref, xmlsig.constants.TransformInclC14N)
ki = xmlsig.template.ensure_key_info(signature)
data = xmlsig.template.add_x509_data(ki)
xmlsig.template.x509_data_add_certificate(data)
qualifying = template.create_qualifying_properties(signature, etsi="xades")
props = template.create_signed_properties(qualifying,name="SignedPropertiesId")
template.add_production_place(props, city="Praia", state="Santiago", postal_code="7952", country="Cabo Verde")
sdop = template.ensure_signed_data_object_properties(props)
template.add_data_object_format(sdop, reference="#DataReferenceId", mime_type="text/xml")
roots.append(signature)
pw = "R6d1WSpo"
with open(cert_file, "rb") as key_file:
certificate = load_pkcs12(key_file.read(),passphrase=pw.encode('utf-8'))
policy = ImpliedPolicy(hash_method=xmlsig.constants.TransformSha256)
ctx=XAdESContext(policy)
ctx.load_pkcs12(certificate)
ctx.sign(signature)
print(roots.nsmap)
roots.append(signature)
print(roots.nsmap)
et = etree.ElementTree(roots)
return et
生成的 XML 如下：

我不完全确定出了什么问题，因为该文件似乎与我作为示例给出的文件相似，但策略部分除外，因为在 Python2 中，XAdes 库使用 SHA1 作为摘要证书和示例文件使用 SHA256。
这是示例文件：
