NAME

       Data::Password::zxcvbn::Match::UserInput - match class for words that match other
       user-supplied information

VERSION

       version 1.1.2

DESCRIPTION

       This class represents the guess that a certain substring of a password can be guessed by
       using other pieces of information related to the user: their account name, real name,
       location, &c.

       This is a subclass of "Data::Password::zxcvbn::Match::Dictionary".

METHODS

   "make"
         my @matches = @{ Data::Password::zxcvbn::Match::UserInput->make(
           $password,
           {
             user_input => \%user_input,
             # this is the default
             l33t_table => \%Data::Password::zxcvbn::Match::Dictionary::l33t_table,
           },
         ) };

       The %user_input hash should be a simple hash mapping field names to strings. It will be
       converted into a set of dictionaries, one per key, containing words extracted from the
       strings. For example

        { name => 'Some One', address => '123 Place Street' }

       will become:

        { name => { Some => 1, One => 1 },
          address => { 123 => 1, Place => 1, Street => 1 } }

       All words get rank 1 because they're obvious guesses from a cracker's point of view.

       The rest of the logic is the same as for "Dictionary".

   "feedback_warning"
       The warnings for this class are very similar to those for "Dictionary", but they
       explicitly mention the field name. Warnings look like:

        ['The value of the [_1] field is easy to guess','address']

       so your localisation library can translate the warning and the field name separately.
