On WB 3.0/3.1, I've been using AmiTCP 3 (something version 0b2?? Not at my Amiga).
It's text files to setup (the GUI install works to a point), but once setup, it's OK...
It's (version 3) the last free version, 4 has registration/nag screens, but works (30 minutes or something like that?).
AmiTCP 2.x is easier to find and works, but there are a few things that want version 3 or higher...
I haven't tried any of the SSL stuff with it, I just use it for basic browsing (aminet mostly) and FTP and it works great for that...
I seem to remember that easynet is also AmiTCP3, but I don't use easynet..
(I like text files ;-)
