NCHAPMAN UI issues don't seem so crucial to me - and where there is UI feedback it should be constructive, rather than negative or hostile.
What is really needed is some discussion of functionality.
Most importantly, with crypto stuff, is some sort of evaluation of the security. Is the code solid, does it leak info, has this been vetted/reviewed, etc.? I haven't been able to find anywhere a discussion of how secure this program is, and that is what we really need.
