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. |  |
