Hi,
You will have to go through Openssl source code.
Have a look at following files:
1. x509_v3.c (around line 74), You will find the following method:
int X509v3_get_ext_by_NID(const STACK_OF(X509_EXTENSION) *x, int nid,
int lastpos)
{
ASN1_OBJECT *obj;
obj=OBJ_nid2obj(nid);
if (obj == NULL) return(-2);
return(X509v3_get_ext_by_OBJ(x,obj,lastpos));
}
Hope this helps.
