## bignum bignum — Big numbers support functions implementation for NSS. |
## Stability Level Stable, unless otherwise indicated ## Functions
SECItem * | xmlSecNssNodeGetBigNumValue ()
int | xmlSecNssNodeSetBigNumValue ()
## Description ## Functions ### 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. |
a | a SECItem containing the BigNum value. |
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. ## Types and Values
