What Hacker News says?
For folks discovering this: Unfortunately, this isn’t a good idea, and can seriously harm your system. I’ll be the first to tell you that I believe Google and Mozilla have done a lot for supervising TLS, but realize that the trust stores contain many other non-TLS purposes, and with the CAs constrained from TLS issuance (e.g. only trust for S/MIME). CryptoAPI, for its warts, is actually beautifully engineered, in th…

HN discussionnot currently, their move off of OpenSSL to their own libraries makes this more complicated for them to do but I am hopeful they will soon. Here is a summary of where clients were a year ago, opera has support now so its slightly out of date - http://unmitigatedrisk.com/?p=24

HN discussionI totally understand the concern and I think the CA industry as a whole does as well. Moving forward Name Constraints will be adopted (finally) which is a good thing. Today it is supported by the majority of devices on the internet and given how fast browsers update now it wont be too long until the extension can be marked critical. On a semi-related note check out how many governments have their own roots : http://…

HN discussionI think you are misunderstanding. First off so there is no ambiguity let me say clearly that GlobalSign's policies do not allow the use of certificates that chain to our roots to be used for MiTM purposes (or other malicious use cases for that matter). That said there are lots of reasons why a company might want or need to operate their own in house PKI and have that PKI trusted; one easy to understand case is googl…
