Why not require CAs to list all DTPs relied on as an appendix to their audits, with links to the related audits of the DTPs? I think Geoff suggested something like that (and he was in the same meeting I was, and presumably heard all the same discussion I did - no malice there).<br></blockquote><div><br></div><div>I did address this already on the list, in <a href="https://cabforum.org/pipermail/public/2017-April/010767.html">https://cabforum.org/pipermail/public/2017-April/010767.html</a></div><div><br></div><div>I do hope you find that reply useful to understand the discussions that already took place or have been taking place some time.</div><div><br></div><div>As mentioned on my most recent e-mail, it would be most useful for you to share details about Entrust. I appreciate your concern for the hypotheticals, but as no one, besides you raising them in the abstract, has raised them, it does seem rather disrespectful to the many attempts at productive discussion.</div></div></div></div>
