API Group: xmlsec_core_templates
Functions for creating XMLDSig and XMLEnc XML template documents.
XML signature and encryption template functions.
xmlNodePtr xmlSecTmplSignatureCreate(xmlDocPtr doc, xmlSecTransformId c14nMethodId, xmlSecTransformId signMethodId, const xmlChar *id);Source: include/xmlsec/templates.h
Creates a new dsig:Signature/ node with required children.
Creates new dsig:Signature/ node with the mandatory dsig:SignedInfo/, dsig:CanonicalizationMethod/, dsig:SignatureMethod/ and dsig:SignatureValue/ children and sub-children. The application is responsible for inserting the returned node in the XML document.
Parameters:
-
doc— the pointer to signature document or NULL; in the second case, application must later call xmlSetTreeDoc to ensure that all the children nodes have correct pointer to XML document. -
c14nMethodId— the signature canonicalization method. -
signMethodId— the signature method. -
id— the node id (may be NULL).
Returns: the pointer to newly created dsig:Signature/ node or NULL if an error occurs.
xmlNodePtr xmlSecTmplSignatureCreateNsPref(xmlDocPtr doc, xmlSecTransformId c14nMethodId, xmlSecTransformId signMethodId, const xmlChar *id, const xmlChar *nsPrefix);Source: include/xmlsec/templates.h
Creates a new dsig:Signature/ node with a custom namespace prefix.
Creates new dsig:Signature/ node with the mandatory dsig:SignedInfo/, dsig:CanonicalizationMethod/, dsig:SignatureMethod/ and dsig:SignatureValue/ children and sub-children. This method differs from xmlSecTmplSignatureCreate in that it will define the http://www.w3.org/2000/09/xmldsig# namespace with the given prefix that will be used for all of the appropriate child nodes. The application is responsible for inserting the returned node in the XML document.
Parameters:
-
doc— the pointer to signature document or NULL; in the second case, application must later call xmlSetTreeDoc to ensure that all the children nodes have correct pointer to XML document. -
c14nMethodId— the signature canonicalization method. -
