Bad Idea? Comments? Joe - What's the implications of a single issued certificate being cracked, and again for one of the root/policy/issuing set? There's quite a bit of speedy hardware out there today (particularly if you count things like repurposed video processors) and 5 years is a *very* long time in our industry. You can actually hunt down the CPS for most public CA's, and I think you'll find that they put up with the "loads of fun every 11 months or so..." However, for them the implications of a compromised issued cert is potential customer liability, and for an the issuing certificate or above is basically loss of their confidence in their entire business of being a CA. You have to assess the implications based on the expected certificate use for your CA. Hope this helps, /John
