</div>I do like the use of a configuration option to turn on hostname<br>
verification. And as you say there have been requests for this<br>
feature in the past, but there have also been posts of patches<br>
implementing it in the past (e.g.<br>
<a href="http://stunnel.mirt.net/pipermail/stunnel-users/2010-March/002613.html" target="_blank">http://stunnel.mirt.net/pipermail/stunnel-users/2010-March/002613.html</a><br>
by me, but sans the option bit :-).</blockquote><div><br></div><div>For some reason your patch didn't turn up when I was searching for this feature before.</div><div><br></div><div>My thinking is that having an option for it makes a big difference.</div>
<div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">I do have some questions though:<br>
<br>
1. If I read this patch correctly it only checks CN, is that correct?<br></blockquote><div><br></div><div>Correct.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
2. Is there any particular reason for not including SAN in the<br>
verification as well?<br></blockquote><div><br></div><div>I confess that I have never heard of anything called SAN in the context of SSL/TLS, and I can't find anything about it online. Do you have a link?</div><div> </div>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
3. Are the patches released under GPL?<br></blockquote><div><br></div><div>No, I released them into the public domain since Michel requires that for any patches that are to be incorporated into mainline stunnel.</div><div>
