Well UCS-2 and UCS-4 certificates are quite rare to come by so in most of the
cases you have a readable string.

I don't have an example but in brief you call _get_dn_oid() using a counter
for index. For value 0 of the counter you get the first OID, which will be
something like 18.104.22.168.5 (null terminated string).
You use this OID to get_dn_by_oid() function with indx==0 to get the actual
In some certificates there could be a duplicate entry of an OID. In that case
you should increase the index number to get_dn_by_oid() to get the second
