Hi Claes, Sorry for the delay answering to your e-mail. Please find my comments below. > Section 3.3.1 Widget Attributes: > * Why is only "common name" used for distributor, distributor root, author and author root certificates? Don't we the whole "subject" to get a more flexible identification of a widget resource? I see your point and agree that considering the whole subject for the root certificates may make more sense, since the subject for the root certificates it very likely to stay the same. However, for other certificates I don't believe using the whole subject to identify a widget is the best option, since: i) the probability that the fields in the subject change is very high; ii) according to the standards the fields in the subject are order independent, which means that when comparing the content of the subject with the policy, a different order could mean that the subject-match is not met even if the subject fields have the same values; iii) there is no limit on the size of the subject, which could potentially be a problem. > Section 3.3.2 Website Attributes: > In order to securely identify a web site and achieve the granularity of a specific web application, don't we need attributes for the site's server certificate? I also suggest that server certificate attributes are added: > * Suggest that the whole "subject" is used instead of only "common name" for the root certificate. Agree in the case of the root certificate. > * Suggest to add: key-server-subject: The subject field of the server certificate chained to by the site certificate. Empty bag if none. Sorry I don't understand this comment... What is the difference between the site certificate and the server certificate? > * Suggest to add: key-server-fingerprint: The fingerprint of the root certificate chained to by the site certificate. Empty bag if none. Do you mean "server certificate"? Let me know what you think. Thanks, Laura
