I like the concept of shorter validity periods, but I’d suggest a 13 month validity period rather than 12. That way subscribers can renew annually with a one month buffer period.
Jeremy From: Public [mailto:[email protected]] On Behalf Of Ryan Sleevi via Public Sent: Tuesday, January 31, 2017 8:50 PM To: CABFPub <[email protected]> Cc: Ryan Sleevi <[email protected]> Subject: [cabfpub] Draft Ballot 185 - Limiting the Lifetime of Certificates I'm looking for two endorsers to publicly endorse this ballot. Background: The validity period of certificates represents the single greatest impediment towards improving the security of the Web PKI. This is because it sets the upper-bound on when legacy behaviours may be safely deprecated, while setting a practical lower-bound for how long hacks and workarounds need to be carried around by clients. Further, in the event of misissuance related to internal control failures, rather than external security failures - for example, misissuance due to failing to properly vet subject information - the validity period represents the risk and exposure to customers and relying parties in the absence of revocation information (for example, constrained environments). To keep this vote simple, it avoids any discussion of the reuse of validation information, described in Section 4.2.1 of the Baseline Requirements and Section 11.14.3 of the EV Guidelines. The following motion has been proposed by Ryan Sleevi of Google, Inc and endorsed by ___ of ___ and ___ of ___ to introduce new Final Maintenance Guidelines for the "Baseline Requirements Certificate Policy for the Issuance and Management of Publicly-Trusted Certificates" and the "Guidelines for the Issuance and Management of Extended Validation Certificates" -- MOTION BEGINS -- Modify Section 6.3.2 of the "Baseline Requirements Certificate Policy for the Issuance and Management of Publicly-Trusted Certificates" as follows: Replace Section 6.3.2 with: """ 6.3.2. Certificate Operational Periods and Key Pair Usage Periods Subscriber Certificates issued on or after 1 May 2017 MUST NOT have a Validity Period greater than twelve (12) months. Subscriber Certificates issued prior to 1 May 2017 MUST NOT have a Validity Period greater than thirty-nine (39) months. """ Modify Section 9.4 of the "Guidelines for the Issuance and Management of Extended Validation Certificates" as follows: Replace Section 9.4 with: """" 9.4 Maximum Validity Period for EV Certificate EV Certificates issued on or after 1 May 2017 MUST NOT have a Validity Period greater than twelve (12) months. EV Certificates issued prior to 1 May 2017 MUST NOT have a Validity Period greater than twenty seven (27) months. """ -- MOTION ENDS --
