Arguments were weak on both sides, but the "keep banning P-521" side was chosen at the end. As noted by others, the ban was checked into draft policy on 2017-Feb-20 and took effect upon publication on 2017-Feb-28 . There was no explicit transition rule for existing certificates, thus certificates issued before 2017-Feb-28 are presumably exempt until their normal expiry. > Below is a list of unexpired, unrevoked certificates which contain P-521 > public keys (grouped by CA Owner and ordered by notBefore): > > Sectigo > crt.sh URL, notBefore, notAfter, issuer CN > -- > https://crt.sh/?id=6371802, 2015-01-23, 2020-01-22, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=13764502, 2015-10-17, 2019-01-16, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=308269873, 2016-10-22, 2019-10-09, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=307896586, 2017-01-23, 2019-01-23, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=308306899, 2017-01-27, 2020-01-27, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=308113189, 2017-03-22, 2020-03-06, InCommon ECC Server CA > https://crt.sh/?id=307650153, 2017-03-26, 2020-03-25, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=307656068, 2017-04-20, 2020-07-18, COMODO ECC Organization > Validation Secure Server CA > https://crt.sh/?id=307534525, 2017-05-18, 2020-05-18, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=308201491, 2017-06-27, 2020-06-26, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=292253731, 2017-12-31, 2019-12-31, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=325088752, 2018-02-07, 2019-02-07, Gandi Standard SSL CA 2 > https://crt.sh/?id=495848274, 2018-02-25, 2019-02-25, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=363803336, 2018-03-23, 2020-05-23, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=369709685, 2018-03-29, 2019-04-28, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=369824505, 2018-03-29, 2020-03-25, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=377999330, 2018-04-05, 2020-04-04, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=395687551, 2018-04-14, 2019-04-29, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=441476932, 2018-04-14, 2019-04-29, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=419677583, 2018-04-25, 2020-04-24, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=419685986, 2018-04-25, 2020-04-24, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=441178023, 2018-05-05, 2019-05-05, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=441178000, 2018-05-05, 2019-05-05, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=447475737, 2018-05-07, 2020-05-06, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=447484644, 2018-05-07, 2020-05-06, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=453793669, 2018-05-10, 2019-05-10, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=453793685, 2018-05-10, 2019-05-10, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=455176361, 2018-05-11, 2019-05-11, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=455176321, 2018-05-11, 2019-05-11, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?id=463185238, 2018-05-15, 2019-05-15, USERTrust ECC Domain > Validation Secure Server CA > https://crt.sh/?id=463092619, 2018-05-15, 2019-05-12, USERTrust ECC Domain > Validation Secure Server CA > https://crt.sh/?id=463092603, 2018-05-15, 2019-05-12, USERTrust ECC Domain > Validation Secure Server CA > https://crt.sh/?id=463185322, 2018-05-15, 2019-05-15, USERTrust ECC Domain > Validation Secure Server CA > https://crt.sh/?id=499794005, 2018-06-01, 2020-02-29, COMODO ECC Domain > Validation Secure Server CA > https://crt.sh/?i
Re: P-521 Certificates
Thanks Corey, Ryan, and Jonathan. In one of the bugs that Ryan created, the CA stated that it's not clear if or when Mozilla requires revocation of these P-521 certificates. I believe the answer is that we do not require revocation. Our policy (section 6) explicitly requires CAs to abide by the BR revocation rules (section 4.9.1.1), but these certificates do not meet any of those requirements. - Wayne On Tue, Jan 8, 2019 at 11:30 AM Jonathan Rudenberg via dev-security-policy < dev-security-policy@lists.mozilla.org> wrote: > On Mon, Jan 7, 2019, at 21:26, Corey Bonnell via dev-security-policy wrote: > > (Posting in a personal capacity as I am no longer employed by Trustwave) > > > > Mozilla Root Store Policy section 5.1 > > ( > https://www.mozilla.org/en-US/about/governance/policies/security-group/certs/policy/) > > > prohibits the use of P-521 keys in root certificates included in the > > Mozilla trust store, as well as in any certificates chaining to these > > roots.

Re: P-521 Certificates
Thanks Corey for reporting these. As you note, this policy came in to force with Policy 2.4, which as noted in https://wiki.mozilla.org/CA/Root_Store_Policy_Archive , had a compliance date of February 28, 2017.
