The ASN1 object utility functions process ASN1_OBJECT structures which are
a representation of the ASN1 OBJECT IDENTIFIER (OID) type.
-For convenience, OID's are usually represented in source code as numeric
-identifiers, or B<NID>'s. OpenSSL has an internal table of OID's that
-are generated when the library is built, and their corresponding NID's
-are available as define'd constants. For the functions below, application
-code should treat all returned values -- OID's, NID's, or names -- as
-constants.
OBJ_nid2obj(), OBJ_nid2ln() and OBJ_nid2sn() convert the NID B<n> to
an ASN1_OBJECT structure, its long name and its short name respectively,
int new_nid;
ASN1_OBJECT *obj;

new_nid = OBJ_create("1.2.3.4", "NewOID", "New Object Identifier");
obj = OBJ_nid2obj(new_nid);
be set to a positive value. A buffer length of 80 should be more
than enough to handle any OID encountered in practice.
-Many of the functions here should probably be changed to return B<const>
-pointers. But the lack of consistency makes that too awkward to do.
