mkpwd

mkpwd is a password generating program. It is designed to satisfy
a scalable range of security demands. It's standard behavior is
to generate one password consisting of any of all printable ASCII
characters (32-128) with a length between 6 and 10.
You can modify the way passwords are generated via command-line
switches. You can specify a length range, the characters used and
even let mkpwd generate passwords which are kind of readable and
therefore easier to remember
