Hi Adriano, My apologies! It was in the past discussed about limiting timestamping to 72 or 75 months alltogether, then not requiring the SubCAs to be offline. The compromise here still allows up to 135 month timestamp certificates, if the SubCAs are offline.
Mind you there’s no current limit to SubCA validity periods yet, but I would
like to limit this to in a future ballot as well
Regards,
Martijn

(v2): Timestamping Private Key Protection
Hi,
wouldn't it have been a little kinder to wait for an answer to the question I
asked on Friday 5?
It may be that the answer was obvious, but it remains unclear to me where that
72 months comes from.....
