Inclusion of OID
How to include the following OID's 1. Serial No 2. Postal Address 3. Postal Code just like other OID's for Example . CN,OU,St etc... kindly suggest me how to incorporate them.
In what part specifically?
If you mean in the parser for certificates, you should add the OIDs to
oid_x520_attr_type in oid.c.
That would cover it all as far as I can foresee now.
