      @sleevi_ @jmhodges On a technical level, similar - but different. *Knowing* it's a wildcard lets insiders and outsiders respond accordingly.

      @konklone @jmhodges I don't think I agree. Sell me on an actual way people or apps use that data today - not a hypothetical feel-good way :)

      @sleevi_ @jmhodges Extremely few organizations use CT today, and those that do seem to have their act together.

      @sleevi_ @jmhodges Take an average org that doesn't, where many subdomains are managed by different teams, and there's no central cert logs.

      @sleevi_ @jmhodges Even if one of those teams attends to CT, they won't be able to notice their own misissuance when the names are redacted.

      @sleevi_ @jmhodges And obviously the outside world can't use redacted cert info very well either, weakening the logs' oversight potential.

      @konklone @jmhodges That is a vague statement without any merit. Describe what the outside party does that they can't with redaction.

      @sleevi_ @jmhodges It has plenty of merit. Proof of misissuance is one of many uses for CT. Investigation is an actual thing.

      @konklone @jmhodges I think you're entirely off the mark, but 140 characters is no good to hash it out. You're still talking in abstract.

      @sleevi_ @jmhodges ...? This isn't abstract, and I provided one concrete example already in this thread from my own life.

      @konklone @sleevi_ @jmhodges IMO, we should replace redaction with the use of a name-constrained intermediates that have a "redaction" ext.

          @sleevi_ @konklone @jmhodges The processing would become sane. W/ current redactoin you have to recalculate a hash of modified cert. Crazy.

          @BRIAN_____ @konklone @jmhodges Oh, on that I totally agree with you. But complexity is necessary because of all the broken legacy.

          @BRIAN_____ @konklone @jmhodges CAs will still be shy of NCs for another decade, and if I view the ecosystem as a whole, I don't blame them

          @BRIAN_____ @konklone @jmhodges So we shift the complexity to new. Incremental moves, even complex, don't need to be anathema.

          @BRIAN_____ @konklone @sleevi_ @jmhodges NC CAs don't easily scale for many orgs with changing name portfolio. Works for some, though.
