| OID information is generated via a series of perl scripts. In order, the full |
| list of commands to run are: |
| |
| perl objects.pl objects.txt obj_mac.num ../../include/openssl/nid.h |
| perl obj_dat.pl ../../include/openssl/nid.h obj_dat.h |
| |
| objects.txt contains the list of all built-in OIDs. It is processed by |
| objects.pl to output obj_mac.num and nid.h. obj_mac.num is the list of NID |
| values for each OID. This is an input/output parameter so NID values are stable |
| across regenerations. nid.h is the header which defines macros for all the |
| built-in OIDs in C. |
| |
| nid.h is read by obj_dat.pl to generate obj_dat.h. obj_dat.h contains the |
| ASN1_OBJECTs corresponding to built-in OIDs themselves along with lookup tables |
| for search by short name, OID, etc. |
