Their blog suggests otherwise:
https://boxcryptor.desk.com/customer/portal/articles/573769-is-boxcryptor-available-for-linux-
but I suppose that just means they are referring to what is now known as Boxcryptor Classic (1.x).
Not realizing that, I installed encfs on my OpenSuSE system and mounted my Dropbox folder using it. Unfortunately, all I see is an empty directory. I guess I'm stuck, right? There is no way to view Boxcryptor (2.x)-encrypted files on Linux?
