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
