Constructor Details

#initialize(len = (8..12)) ⇒ Password

Creates a new password generator. The length len might be an Integer or a Range.

def initialize len = (8..12)
  if len.is_a? Integer
    @length = Range.new(len-1, len+1)
  elsif len.is_a? Range
    @length = len

    raise ArgumentException, "Length is neither an Integer nor a Range."

end

Class Method Details

.pronounceable(len = (8..12)) ⇒ Object

Similar to #pronounceable, this generates a pronounceable password.

def pronounceable len = (8..12)
  self.new(len).pronounceable
end

.random(len = (8..12)) ⇒ Object

Similar to #random, this generates a random password.

def pronounceable
  size = @length.to_a[rand(@length.count)] - 2
  f, pw = true, ''
  size.times do
    pw << (f ? CONSONANTS[rand * CONSONANTS.size] : VOWELS[rand * VOWELS.size])
    f = !f
  end
  pw
end

#random ⇒ Object

Unlike #pronounceable, this does not ensure the pronounceability and will include some special characters, but will exclude “unfriendly” characters (like 0, O).
