I'm not aware that they're doing anything that is not allowed by RFC 3280. Both RFC 3280 and RFC 5280 define a minimum set of things that a "conformant" product must do, and also a bunch of optional things that are allowed but not required. As you might expect, this means that there are numerous products out there that do not implement all the optional bells and whistles. NSS implements quite a few of the optional features, but not all. As a CA, if you want your certs to be usable by the widest set of products possible, you will restrict yourself to using only the features that the RFC (either one) requires all conformant implementations to support. If you're a CA making certs only for use with certain products, all of which are known to support some optional feature, then using that optional feature is more reasonable. This CA is using optional features that are not ubiquitous, yet expects its certs to be widely accepted throughout the web. That doesn't violate any RFC, but it may keep their certs from being universally accepted. Lots of CAs learn this lesson the hard way, but they do learn. IINM, the South Korean's no longer make their certificate policy extensions critical. The Hungarians no longer make their qcStatement extensions critical, IINM. It won't be that easy in this case, but I expect the CA will find a solution. -- dev-tech-crypto mailing list dev-tech-crypto@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-tech-crypto
