我正在尝试使用 pyxmlsec/xmlsec/libxml2 对 XML 文件进行签名,但它失败了(sigCtx->signValueNode == NULL:error=100:assertion
)。
当我从命令行运行时,它运行顺利:
xmlsec1 sign --output signed.xml --pkcs12 c.pfx --pwd mypwd tobesigned.xml
我的 Python 代码:
libxml2.initParser()
libxml2.substituteEntitiesDefault(1)
xmlsec.init()
xmlsec.cryptoAppInit(None)
xmlsec.cryptoInit()
doc_xml = libxml2.parseMemory(xml, len(xml))
signature_node = xmlsec.findNode(
doc_xml.getRootElement(),
xmlsec.NodeSignature,
xmlsec.DSigNs,
)
signer = xmlsec.DSigCtx()
key = xmlsec.cryptoAppKeyLoad(
filename=str(self.issuer.certificate.path),
format=xmlsec.KeyDataFormatPkcs12,
pwd=str(self.issuer.certificate_password),
pwdCallback=None,
pwdCallbackCtx=None,
)
signer.signKey = key
signer.sign(signature_node) # error!
...
完整的错误跟踪:
func=xmlSecDSigCtxProcessSignatureNode:file=xmldsig.c:line=463:obj=unknown:subj=dsigCtx->signValueNode == NULL:error=100:assertion:
func=xmlSecDSigCtxSign:file=xmldsig.c:line=303:obj=unknown:subj=xmlSecDSigCtxSigantureProcessNode:error=1:xmlsec library function failed:
有小费吗?
谢谢!
