I'm having a hard time to get 'protect' to work. First, if mydata.tgz.bfe is large, then Tiny Core just boots without extract its content. Second, which may be related to the first, is that "filetool.sh -sb" does not encrypt mydata.tgz. I vaguely remember that when using 'protect', there will be a file that contains the password phrase. Perhaps I shall look into that first. I have tried to find more info about this, but I did not succeed. Does someone know where this passphrase file is located?
