Software :: Import CAcert SSL Root Certificate To Use With Xchat IRC Client?

I'm trying to use Xchat, to communicate with a server which uses CAcert root certificate(s) for its SSL connection. I have Xchat all configured, and it works fine when I connect without SSL, but I'm getting pretty miffed about how to get it to find/use whatever local certificates I'm supposed to have, assuming I actually *have* these certs installed somewhere. This seems like it should be less difficult than I'm making it out to be. I've been to CAcert's website and their Wiki, and while they have the root certificates available for download (which I did, as well as inadvertently installing them into my browser, where they probably already were anyway) the only instructions I saw in their "Linux" docs department, on how/where to use/put them, were for a couple RH based distros, and some other distro I'm not using.

I checked the Xchat website and had a somewhat semi-thorough look around their user forum, but didn't find what I need there either. The openssl man page (yes, it's installed) doesn't tell me what I want, and xchat doesn't even *have* a man page. An LQ search turns up a few off-topic threads, mainly several years old and with very little in the way of replies. This ought to be easy :/ and I bet it is easy, with the right documentation in front of me. This is Slackware 13-64/-current. I've got /etc/ssl/certs folder, with nothing in it; and I have an /etc/ssl/openssl.cnf file which *appears* to be intended for using SSL on my own server (don't want that).

In case it helps, here's what the server tells me when I have enabled SSL and try to connect:

Code:

[15:47] * Version: TLSv1/SSLv3, cipher AES256-SHA (256 bits)
[15:47] * Connection failed. Error: unable to get local issuer certificate.? (20)

Can someone point me to a decent link/tutorial about how to connect by IRC, (using Xchat if that matters), and have it find my SSL certs and/or where/how I get the CA root certificates in the right location for this to work?
