Thanks Trevor. Ok so if we set the Max Age to 1 day or 10 days or 30 or 90 so what are the realistic impacts? Increased Infrastructure how much? I have not seen the tradeoffs cost(risks or added infrastructure) vs. benefits. I have been reading the argument pro's and con's and the issue does n

Why can't the Max-Max-AGE equal a formula Max age= (average usage)*2+1day This should accommodate both and not the best for either. Chuck From: Yoav Nir [mailto:y...@checkpoint.com] Sent: Tuesday, June 04, 2013 7:08 AM To: Tobias Gondrom Cc: Subject: Re: [websec] Consensus call: Issue #57 (ma

Well. I am not strongly voting for it. The point is, to have a hard limit of 30 days under the assumption of the existence of such infrastructure would be worse, because then we would need to rely on such infrastructure in all normal operation cases. While with my approach we would need the infras

But doesn't this introduce a lot of infrastructure? If we want to find out a hash of the public key for an HTTPS server using heavy infrastructure, we might as well use DANE, no? Yoav On Jun 4, 2013, at 1:04 PM, Tobias Gondrom mailto:tobias.gond...@gondrom.org>> wrote: Hi Trevor, hi all, (ag

Hi Trevor, hi all, (again no hats) actually regarding browser lookups of pin lists: I rather have the pins work unlimited and all the time even without pin lists. But your idea might in fact be a solution to enable the unlimited pin times. Instead of constantly distributing the list of pins, we
