rassphrase is an implementation of the Diceware passphrase method for Ruby. It's used to generate secure passphrase used for passwords.

Diceware™ is a method for picking passphrases that uses dice to select words at random from a special list called the Diceware Word List. Each word in the list is preceded by a five digit number. All the digits are between one and six, allowing you to use the outcomes of five dice rolls to select one unique word from the list.
