## Description ## Details ### xmlSecOpenSSLNodeGetBNValue ()
    BIGNUM*     xmlSecOpenSSLNodeGetBNValue     (const xmlNodePtr cur,
                                                 BIGNUM **a);
Converts the node content from CryptoBinary format (http://www.w3.org/TR/xmldsig-core/sec-CryptoBinary) to a BIGNUM. If no BIGNUM buffer provided then a new BIGNUM is created (caller is responsible for freeing it).
cur : | the poitner to an XML node.
a : | the BIGNUM buffer.
Returns : | a pointer to BIGNUM produced from CryptoBinary string or NULL if an error occurs.
### xmlSecOpenSSLNodeSetBNValue ()
    int         xmlSecOpenSSLNodeSetBNValue     (xmlNodePtr cur,
                                                 const BIGNUM *a,
                                                 int addLineBreaks);
Converts BIGNUM 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.
cur : | the pointer to an XML node.
a : | the BIGNUM.
addLineBreaks : | if the flag is equal to 1 then linebreaks will be added before and after new buffer content.
Returns : | 0 on success or -1 otherwise.
