xkcdpass - XKCD Style Password Generator

Generate passwords made up by four (or any other number of) random words from a word list (7776 common English words).

With the default of 4 words, there are 7776^4 = 3656158440062976 possible word combinations, which corresponds to about 51 bits of entropy. When using 6 words, the entropy is increased to about 77 bit.
