Subject: Re: CVE request: xchat/hexchat don't properly verify
SSL certificates
A lot of the time IRC networks will not pay for a verified SSL cert due to
the fact that the kind of SSL cert they would need (a wildcard one) is
financially prohibitive. I don't think this is a security bug with hexchat
more a symptom of the fact that SSL combines encryption and identity
verification where sometimes people only want the former.
