NAME

6       Data::Password::zxcvbn::Match::Regex - match class for recognisable
7       patterns in passwords
8

VERSION

10       version 1.1.2
11

DESCRIPTION

13       This class represents the guess that a certain substring of a password
14       can be guessed by enumerating small languages described by regular
15       expressions. By default, the only regex used is one that matches recent
16       years (yes, this is very similar to what "Date" does).
17

ATTRIBUTES

19   "regexes"
20       Hashref, the regular expressions that were tried to get this match. The
21       values are arrayrefs with 2 elements: the regex itself, and the
22       estimated number of guesses per character; for example:
23
24         digits => [ qr[(\p{Nd}+)], 10 ],
25
26   "regex_name"
27       The name of the regex that matched the token.
28

METHODS

30   "make"
31         my @matches = @{ Data::Password::zxcvbn::Match::Regex->make(
32           $password,
33           { # this is the default
34             regexes => \%Data::Password::zxcvbn::Match::Regex::regexes_limited,
35           },
36         ) };
37
38       Scans the $password for substrings that match regexes in "regexes".
39
40       By default, the only regex that's used is one that matches recent years
41       expressed as 4 digits. More patterns are available as
42       "\%Data::Password::zxcvbn::Match::Regex::regexes" (which you can also
43       get if you say "regexes => 'all'"), or you can pass in your own
44       hashref.
45
46   "estimate_guesses"
47       For the "recent_year" regex, the number of guesses is the number of
48       years between the value represented by the token and a reference year
49       (currently 2017).
50
51       For all other regexes, the number of guesses is exponential on the
52       length of the token, using as base the second element of the matching
53       pattern (i.e. "$self->regexes->{$self->regex_name}[1]").
54
55   "feedback_warning"
56   "feedback_suggestions"
57       This class suggests not using recent years. At the moment, there's no
58       feedback for other regexes.
59
60   "fields_for_json"
61       The JSON serialisation for matches of this class will contain "token i
62       j guesses guesses_log10 regex_name".
