A Diceware Passphrase Implementation
Description
The Diceware method can be used to generate strong passphrases.
In short, you roll a 6-faced dice 5 times in a row, the number obtained is
matched against a dictionary of easily remembered word. By combining together 7
words thus generated, you obtain a password that is relatively easy to remember,
but would take several millions years (on average) for a powerful computer to guess.
