This is not defined anywhere. Given that a Subscriber could be getting a certificate with CA:True in the basic constraints (e.g. the Subscriber is a subordinate CA), we wanted to change “Subscriber Certificate” to “End-entity Certificate” in most locations and create a definition for “End-entity Certificate”.</div><br class=""><blockquote type="cite" class=""><div class=""><div dir="ltr" class=""><div class="gmail_extra"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;border-left-color:rgb(204,204,204);padding-left:1ex"><div lang="EN-US" link="#0563C1" vlink="#954F72" class=""><div class=""><p class=""> <u class=""></u><u class=""></u></p><p class=""><u class=""></u><span class="">2.<span style="font-style:normal;font-variant:normal;font-weight:normal;font-stretch:normal;font-size:7pt;line-height:normal;font-family:'Times New Roman'" class=""> </span></span><u class=""></u>Where the intent of the guidelines is to discuss the entity that operates a certification authority, replace the word CA with the phrase “certification service provider”, CSP, or similar.
