NAME

Data::Password::zxcvbn::Match::Date - match class for digit sequences that look like dates

VERSION

DESCRIPTION

This class represents the guess that a certain substring of a password, consisting of digits and maybe separators, can be guessed by scanning dates in the recent past (like birthdays, or recent events).

ATTRIBUTES

year

Integer, the year extracted from the token.

separator

String, possibly empty: the separator used between digits in the token.

METHODS

estimate_guesses

The number of guesses is the number of days between the extracted "year" and a reference year (currently 2017), multiplied by the possible separators.
