6. Discussion of approach and deliverables
It was agreed to begin a discussion of certificate profiles starting at the S/MIME end entity, working up the chain, in comparison to major requirements and standards. The worksheet currently includes aspects of standards from Mozilla, Gmail and the US Federal PKI (thanks for Wendy Brown's assistance):
Certificate Issuers were asked to review their profiles for variance from these settings for discussion, with feedback preferred on the public list.
Certificate Consumers were requested if there are technical requirements (must have/can't have) imposed by their products or services on certificates.
Ben Wilson was requested to check the profile against the Mozilla program requirements.
Pertaining to Serial Number, it was discussed whether the requirement for 64 unpredictable bits was a legacy of the SHA1 deprecation or a necessary ongoing security feature. It is a requirement of the Mozilla Root Store Policy 5.2.
Pertaining to Signature Algorithm, assistance was requested in either obtaining an English translation of BSI TR-03166 or in translating the text from German (with particular interest in the use of RSASSA-PSS). It was noted that ECDSA SHA-512 is not supported under Mozilla, with the question if the same applies to Thunderbird.
Pertaining to Validity Period, there was discussion relating to the tradeoffs between shorter validity for crypto agility as championed in TLS, the use of tokens found in many S/MIME implementations, and in use cases such as email gateways. It was proposed that domain certificates would benefit from a separate profile. Discussion to be continued.
6. Any Other Business
Again, WG members are encouraged to submit relevant standards and requirements to the public list.
7. Next call
The next call will take place on September 2, 2020 at 11:00am Eastern Time.
