i guess the title said it all... ? need some files to be hidden and not to be seen by the tracker but can easily be accessed by me by simply tping a password.
I haven't tried this so I might be steering you into a dead end but gpg is installed by default so you should be able to generate a key or import one you already have and encrypt your files in the terminal. If you're not familiar with the syntax, just Google gpg for some tutorials.
