Data::Password::zxcvbn::Match::UserInput(3pm)

"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.
