This script generates passwords using xkcd's algorithm (stringing together several random dictionary words). This gives passwords that are strong and easy to remember.
Usage: gen-password <options>
Options:
--help Prints this screen.
--dictionary=(file) Specifies dictionary; default is "/usr/share/dict/words".
--numwords=N Specifies number of words; default is 4.
--debug-dict Prints dictionary debugging information.
NOTE - This uses rand() for random number generation. While that's
not cryptographically strong, it should be more than good enough for this
application.
The weakness in rand() means that if you know the first die roll you know
that certain subsequent die rolls are a bit more likely than others. In this
case, if an attacker had the dictionary list and knew what version of
rand() was being used, they would only need to make a few trillion guesses
instead of a few quadrillion. That's still better than most passwords.
