Java in a Nutshell, 5th Edition [Electronic resources] نسخه متنی

This class is a
transparent representation of a password used in password-based
encryption (PBE). The password is stored as a char
array rather than as a String, so that the
characters of the password can be overwritten when they are no longer
needed (for increased security).
