xmlSecNssNodeGetBigNumValue ()

SECItem *
xmlSecNssNodeGetBigNumValue (PRArenaPool *arena,
                             const xmlNodePtr cur,
                             SECItem *a);

Converts the node content from CryptoBinary format (http://www.w3.org/TR/xmldsig-core/sec-CryptoBinary) to a SECItem. If no SECItem object provided then a new one is created (caller is responsible for freeing it).

Parameters

arena	the arena from which to allocate memory
cur	the pointer to an XML node.
a	a SECItem object to hold the BigNum value

Returns

a pointer to SECItem produced from CryptoBinary string or NULL if an error occurs.

xmlSecNssNodeSetBigNumValue ()

int
xmlSecNssNodeSetBigNumValue (xmlNodePtr cur,
                             const SECItem *a,
                             int addLineBreaks);

Converts SECItem to CryptoBinary string (http://www.w3.org/TR/xmldsig-core/sec-CryptoBinary) and sets it as the content of the given node. If the addLineBreaks is set then line breaks are added before and after the CryptoBinary string.

Parameters

cur	the pointer to an XML node.
