[Servercert-wg] [EXTERNAL] Clarification about EVG 9.2.4

Dimitris – When registration is done at the local level, it could be ambiguous if we allow CAs to only list subject:jurisdictionLocalityName and the subject:jurisdictionCountryName, but omit the subject:jurisdictionStateOrProvinceName.

I have listed below all the towns in the US named either “Salem” or “Springfield”  (thanks, Wikipedia) – there are a lot of them.  If place of registration in an EV certificate is just listed as “Salem, US” or “Springfield, US” there would be a potential disambiguation problem.

I think Bruce Morton’s interpretation is correct – if the place of official registration is at the locality level, CAs should also include the State or Province (if any) and the Country.

Hi Cynthia,

I think your comment is not so much related to the issue at hand. The language for JoI-Locality is the one that needs to be clarified. We are very clear about the other cases.

My original interpretation was that no matter what, if an organization is registered at the locality level, the subjectDN MUST always include subject:jurisdictionLocalityName AND subject:jurisdictionStateOrProvinceName AND the subject:jurisdictionCountryName. After reading it more carefully I came to the conclusion that there is a different interpretation which was confirmed by Jeremy.

Now, all we need to do is confirm that this was the original intent and if so, we may be able to improve this part of the EVG to make it more clear that it is allowed to include subject:jurisdictionLocalityName without a subject:jurisdictionStateOrProvinceName entry, for the case where the Country doesn't offer registration at the State or Province level.

Is there anyone that objects to this interpretation?

Thank you,

My interpretation would be that for example if we take Apple as an example, it would be jC=US, jST=California but no locality.
I understand that this will get very complicated, as for example, in Sweden, limited companies are at a national level while for example sole proprietorships are at a county level.

I disagree as that's not what the language says. It says to include the state field if the state regulates registration of the locality. I can't speak to Toronto and how it incorporates entities (if it does), but I think the answer depends heavily on the locality, the type of entity, and how registration occurs.

Subject: Re: [Servercert-wg] [EXTERNAL] Clarification about EVG 9.2.4

I guess I am saying that you must include the jurisdiction level where the organization was registered. If the organization was registered at the locality level, then the certificate must include jL and jC. If the country has no states or provinces, then jST must not be used. If the country has states or provinces, then jST must be used, where jST is the state/province for jL.

Let’s say that we have a company based in Toronto, Ontario, Canada; if it was registered in:

  1.  Canada, then the certificate must only have jC=CA
  2.  Ontario, then the certificate must only have jST=Ontario and jC=CA. It cannot have jL=Toronto as the company was not registered by a registrar at the locality level.
  3.  Toronto, then the certificate must have all 3, jL=Toronto, jST=Ontario and jC=CA. jST must be included to help identity where the locality is.

Hi Dimitris,

My interpretation is the following:

  1.  If the organization is registered at the country level, then the certificate must include the subject:jurisdictionCountryName.
  2.  If the organization is registered as the state/province level, then the certificate must include the subject:jurisdictionStateOrProvinceName and the subject:jurisdictionCountryName.
  3.  If the organization is registered at the locality level, then the certificate must include the subject:jurisdictionLocalityName and the subject:jurisdictionCountryName; and must include the subject:jurisdictionStateOrProvinceName, only if the locality is in a state/province.

Hi Bruce, thanks for your reply.

The first two are quite clear.

The following:
"and must include the subject:jurisdictionStateOrProvinceName, only if the locality is in a state/province"

is not so clear to me. Perhaps you could elaborate with a couple of theoretical examples? I seems that the StateOrProvince is mixed with Locality in your description but I might have misunderstood.

Dear members,

I would like to ask for a clarification/interpretation about section 9.2.4 of the EV Guidelines and please forgive me if this has been discussed in the past.

9.2.4. Subject Jurisdiction of Incorporation or Registration Field

"Contents: These fields MUST NOT contain information that is not relevant to the level of the Incorporating Agency or Registration Agency. For example, the Jurisdiction of Incorporation for an Incorporating Agency or Jurisdiction of Registration for a Registration Agency that operates at the country level MUST include the country information but MUST NOT include the state or province or locality information. Similarly, the jurisdiction for the applicable Incorporating Agency or Registration Agency at the state or province level MUST include both country and state or province information, but MUST NOT include locality information. And, the jurisdiction for the applicable Incorporating Agency or Registration Agency at the locality level MUST include the country and state or province information, where the state or province regulates the registration of the entities at the locality level, as well as the locality information. Country information MUST be specified using the applicable ISO country code. State or province or locality information (where applicable) for the Subject's Jurisdiction of Incorporation or Registration MUST be specified using the full name of the applicable jurisdiction."

Is it allowed to include a subject:jurisdictionLocalityName without providing a subject:jurisdictionStateOrProvinceName?

The requirement says "And, the jurisdiction for the applicable Incorporating Agency or Registration Agency at the locality level MUST include the country and state or province information, where the state or province regulates the registration of the entities at the locality level, as well as the locality information."

In one interpretation, if there is no "state or province" that regulates the registration of entities but this registration is done at the locality level, then the subject:jurisdictionStateOrProvinceName can be omitted and only the subject:jurisdictionLocalityName is included along with the subject:jurisdictionCountryName. Is this an accurate and valid interpretation?

Thank you,
