; This example demonstrates getting the SERIALNUMBER part of the subject,
; if one such part exists in the cert's subject.
; Not too many certicates include the serial number in the Subject.
; (Chilean issued certificates for SII is one such case where the SERIALNUMBER part exists within the Subject.)

; We could also get the part by the OID.
; See https://oidref.com/2.5.4.5 for a list of OID's in the 2.5.4.* range..
; The OID for SERIALNUMBER is "2.5.4.5"
