I have. There are lots of things in my life that are none of their business. What a boring life you must lead.
Dude, one of the chimps had a hidden camera. I have been to Youtube. Trust me, you don't have any secrets.

One cool trick. encrypt four or five files. The first file has stuff you don't care about. Use a burner key for that one. Encrypt a few random files, with a key you throw away, so you can't decrypt them, even if you want. Next encrypt the files you want to protect, with your main key. Zip them all up, then encrypt one more time.
Even if they torture you, your files are safe. You can't give away the random files, so you know, they will keep the torture up, even if you give them everything you know. This works even better, if you post on a public forum (like Mac Rumors), that you do it.
