Several the results of these discussions, and barrier to change, are evident in the BRs themselves (issuance from a root, the internal server name deprecation date, etc). By eliminating long lived certs, the Forum eliminates one of the major obstacles in improving the industry, permitting the Forum to become the primary proponent for improvements instead of the browsers (ie, instead of Microsoft announcing that SHA2 is required for all certs three years from now, the Forum could have passed a BR requirement to the same effect).<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Plus, the code signing working group focuses heavily on private key protection. During the discussions, the group estimated that 50% of the problem certificates resulted from stolen or compromised private keys. I imagine the problem is just as bad for SSL. Add on top of that the fact that five-year old information is extremely stale and has likely changed. <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Jeremy <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext'> public-bounces@cabforum.org [mailto:public-bounces@cabforum.org] <b>On Behalf Of </b>kirk_hall@trendmicro.com<br><b>Sent:</b> Thursday, November 28, 2013 7:07 PM<br><b>To:</b> Eddy Nigg (StartCom Ltd.); CABFPub<br><b>Subject:</b> Re: [cabfpub] Ballot 111 - Accelerate Max Certificate Lifetime Reduction Timetable<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='color:windowtext'>Well, so far the existence of 60 month certs has not stopped the browsers from imposing new requirements on CAs and certificates that have an immediate effect on all certs (60 month and 39 month certs alike) – some browsers have even taken the position that new rules in the BRs adopted in July 2012 and made effective in February 2013 would apply *<b>retroactively</b>* to certs issued *<b>before</b>* those dates. <o:p></o:p></span></p><p class=MsoNormal><span style='color:windowtext'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:windowtext'>So I don’t really think it’s true that the existence of 60 month certs issued by some CAs has ever limited changes made by the Forum, or their effective dates.

We all understand that CAs want to nail a customer for as long as possible and make a difference by issuing certificates for long periods of time (irresponsible) because others won't do that - but since this requirement would be applied across the board I believe there will be no competitive disadvantage to any of them.<br><br>However the entire industry will improve once changes can be pushed through within ~ 3 years than currently 5 and previously 10. Being able to act faster and get rid of possible problematic certificates within the time-frame of 3 years without the need of revocation (which would result in a another outcry anyway) is probably a worthy goal. With the current upcoming changes it appears to be a golden opportunity to achieve that.<o:p></o:p></span></p><div><table class=MsoNormalTable border=0 cellspacing=0 cellpadding=0><tr><td colspan=2 style='padding:0in 0in 0in 0in'><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'>Regards <o:p></o:p></span></p></td></tr><tr><td colspan=2 style='padding:0in 0in 0in 0in'><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'> <o:p></o:p></span></p></td></tr><tr><td style='padding:0in 0in 0in 0in'><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'>Signer: <o:p></o:p></span></p></td><td style='padding:0in 0in 0in 0in'><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'>Eddy Nigg, COO/CTO<o:p></o:p></span></p></td></tr><tr><td style='padding:0in 0in 0in 0in'><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'> <o:p></o:p></span></p></td><td style='padding:0in 0in 0in 0in'><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><a href="http://www.startcom.org">StartCom Ltd.</a><o:p></o:p></span></p></td></tr><tr><td style='padding:0in 0in 0in 0in'><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'>XMPP: <o:p></o:p></span></p></td><td style='padding:0in 0in 0in 0in'><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><a href="xmpp:startcom@startcom.org">startcom@startcom.org</a><o:p></o:p></span></p></td></tr><tr><td style='padding:0in 0in 0in 0in'><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'>Blog: <o:p></o:p></span></p></td><td style='padding:0in 0in 0in 0in'><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><a href="http://blog.startcom.org">Join the Revolution!</a><o:p></o:p></span></p></td></tr><tr><td style='padding:0in 0in 0in 0in'><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'>Twitter: <o:p></o:p></span></p></td><td style='padding:0in 0in 0in 0in'><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><a href="http://twitter.com/eddy_nigg">Follow Me</a><o:p></o:p></span></p></td></tr><tr><td colspan=2 style='padding:0in 0in 0in 0in'><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'> <o:p></o:p></span></p></td></tr></table></div><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><o:p> </o:p></span></p><table class=MsoNormalTable border=0 cellpadding=0><tr><td style='background:white;padding:.75pt .75pt .75pt .75pt'><table class=MsoNormalTable border=0 cellpadding=0><tr><td style='padding:.75pt .75pt .75pt .75pt'><pre><o:p> </o:p></pre><pre>TREND MICRO EMAIL NOTICE<o:p></o:p></pre><pre>The information contained in this email and any attachments is confidential <o:p></o:p></pre><pre>and may be subject to copyright or other intellectual property protection. <o:p></o:p></pre><pre>If you are not the intended recipient, you are not authorized to use or <o:p></o:p></pre><pre>disclose this information, and we request that you notify us by reply mail or<o:p></o:p></pre><pre>telephone and delete the original message from your mail system.<o:p></o:p></pre></td></tr></table></td></tr></table><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif";color:windowtext'><o:p> </o:p></span></p></div></body></html>
