NAME

Data::Password::zxcvbn::Match::Sequence - match class for sequences of uniformly-spaced codepoints

VERSION

version 1.0.3

DESCRIPTION

This class represents the guess that a certain substring of a password, consisting of uniformly-spaced codepoints, is easy to guess.

ATTRIBUTES

ascending

Boolean, true if the sequence starts at a lower codepoint and ends at a higher one (e.g. acegi is ascending, 86420 is not).

METHODS

estimate_guesses

The number of guesses is linear with the length of the sequence. Descending sequences get a higher estimate, sequences that start at obvious points (e.g. A or 1) get lower estimates.

feedback_warning

feedback_suggestions

This class suggests not using sequences.

make

my @matches = @{ Data::Password::zxcvbn::Match::Sequence->make(
  $password,
) };

Scans the $password for sequences of characters whose codepoints increase or decrease by a constant.

fields_for_json

The JSON serialisation for matches of this class will contain token i j guesses guesses_log10 ascending.
