In the wake of gmail blanket blocking any archives that have their contents protected with encrypted filenames - is it possible to 'obfuscate' filenames at all? I'll admit I am yet to look into the archive file format/structure to see if this is something achieveable. Some people have a need to keep the filename contents of their archives secure from prying eyes. It would be a lower tier of safety of course, but it would at least help. Thoughts?
