There have been some questions about expected ASN.1 grammar for BR & EV certificates. I’ve created a module that attempts to collect it all.
I found a couple of errors in the tor appendix. I think I got the intent right, but can someone please confirm?
Li-Chun: does this resolve your concerns about lack of documentation?
==> I appreciate your effort to document ASN.1 definition of jurisdictionLocalityName, jurisdictionStateOrProvinceName and jurisdictionCountryName. Currently, EVGL 9.2.5 says these three attributes are defined in RFC 5280, but it is not true. Last summer, I had pointed out this issue and discussed in Redmond F2F meeting day 2.
However, I don’t think it is necessary to duplicate those attributes that already defined in X.520 or RFC 5280, such as countryName, organizationName, givenName, streetAddress, localityName , stateOrProvinceName, postalCode, etc. Even if you add some upper bounds of the directory string length, it is simply a “profiling” of the original attributes. Their semantic will not have different meaning from the original ones. Also, their DER encoding will be still the same as the original ones.
Thanks,
Peter
