How do I install this self-signed SSL certificate?

I haven't been able to connect to the jabber server I've been using (phcn.de) for quite some time now, so I filed a bug report with mcabber. The friendly people there told me to install phcn.de's self-signed certificate, but I can't figure out for the life of me how to do that.

I know I can download something resembling a certificate using

$ gnutls-cli --print-cert -p 5223 phcn.de

Which does give me something to work with:

Resolving 'phcn.de'...

Unfortunately, the above command spits out more than a certificate. Do I need the additional information? If so, what do I need it for? Where do I need to put the certificate file?
