SSL for dcc chat sessions would be nice.... a lot of irc bots for example use a dcc chat interface for administration (EM,Eggdrop,regular mirc bots,and many other flavors). It is fairly common for a dcc chat interface to be used for a bot rather than a private message because of the ability to add authentication (if not built in already) with a lot more ease.
As far as SSL goes in general, im still somewhat irritated by the fact that there is no way to overrider the prompts to acceptance on server connection... it can become very annoying having to check the box (to auto accept in future) and click accept EVERY TIME regardless of how many times it has been done in the past. I spent a conciderable amount of time trying to find an inconcistancy with the server side certificates or a concistancy with those that never seem to save with no luck, seems to me that perhaps it is mirc that is not correctly saving them or recognising the saved ones. This is further evident by the fact that if i clear them all, different ones will be saved properly the next time while others that may have been fine before no longer auto accept once they have been told to.
Sorry to go OT, seemed appropriate to mention again and didnt want to make a new thread as its been mentioned in the past.
