Re: Unknown Intermediates

I definitely consider increased visibility into the vast iceberg that is the public PKI to be a good thing! What set of intermediates are you using? If it's reasonably complete, I doubt we'll do any better than you, though maybe someone here has a particularly clever technique for processing

Re: Unknown Intermediates

I think you're right, it was probably me submitting my corpus - I hope that's a good thing! :-) I only submitted the ones I could verify, would you be interested in the others? Many are clearly not interesting, but others seem like they may be interesting if I had an intermediate I haven't seen.

Re: Unknown Intermediates

One of my hobbies is keeping track of publicly trusted (by any of the major root programs) CAs, for which there are no logged certificates. There's over 1000 of these. In the last day, presumably as a result of these efforts, 50-100 CAs were removed from the list. Cheers, Alex On Thu, Jun 22,

Re: Unknown Intermediates

I noticed there's an apparently valid facebook.com certificate in there (61b1526f9d75775c3d533382f36527c9.pem). This is surprising to me, that seems like it would be in CT already - so maybe I don't know what I'm doing. Let me know if I've misunderstood something. Tavis. On Mon, Jun 19, 2017 at

Thanks Alex, I took a look, it looks like the check pings crt.sh - is doing that for a large number of certificates acceptable Rob? I made a smaller set, the certificates that have 'SSL server: Yes' or 'Any Purpose : Yes', there were only a few thousand that verified, so I just checked those and

Re: Unknown Intermediates

If you're interested in playing around with submitting them yourself, or checking if they're already submitted, I've got some random tools for working with CT: https://github.com/alex/ct-tools Specifically ct-tools check will get what you want. It's all serial, so for
