Hidden TrueCrypt volume
It may happen that you are forced by somebody to reveal the
password to an encrypted volume. There are many situations
where you cannot reflise to reveal the password (for example,
due to extortion). Using a so-called hidden volume allows you to
solve such situations without revealing the password to your
volume.

th a t can be used f o r the
purpose o f secure erasure
(m any o f them are free).

It is very important that you choose a good password. You should
avoid choosing one that contains only a single word that can be found
in a dictionary (or a combination o f 2, 3, or 4 such words). It should
not contain any names or dates of birth. It should not be easy to
guess. A good password is a random combination of upper and lower
case letters, numbers, and special characters, such as @ A = $ * +
etc. We recommend choosing a password consisting o f more than 20
characters (the longer, the better). The maximum possible length is 64
characters.
