Humpf. I looked at that a few times and did not see the obvious. Sigh.
So some progress. using -i and got:
573:d=5 hl=2 l= 3 prim: OBJECT :X509v3 Subject
578:d=5 hl=2 l= 29 prim: OCTET STRING [HEX
Added -strparse 578 and got:
0:d=0 hl=2 l= 27 cons: SEQUENCE
2:d=1 hl=2 l= 25 cons: cont [ 0 ]
4:d=2 hl=2 l= 8 prim: OBJECT :188.8.131.52.184.108.40.206.4
14:d=2 hl=2 l= 13 cons: cont [ 0 ]
16:d=3 hl=2 l= 11 cons: SEQUENCE
18:d=4 hl=2 l= 3 prim: OBJECT :220.127.116.11
23:d=4 hl=2 l= 4 prim: OCTET STRING [HEX DUMP]:01020304
Since I don't know that SubjectAltName content will always start at 578,
I have to do the asn1parse in two steps.
It is a start...
