Data::Password::zxcvbn::Match::UserInput \- match class for words that match other user\-supplied information
.SH "VERSION"
.IX Header "VERSION"
version 1.0.4
.SH "DESCRIPTION"
.IX Header "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.
.PP
This is a subclass of \f(CW\*(C`Data::Password::zxcvbn::Match::Dictionary\*(C'\fR.

\&  my @matches = @{ Data::Password::zxcvbn::Match::UserInput\->make(
\&    $password,
\&    {
\&      user_input => \e%user_input,
\&      # this is the default
\&      l33t_table => \e%Data::Password::zxcvbn::Match::Dictionary::l33t_table,
\&    },
\&  ) };
.Ve
.PP
The \f(CW%user_input\fR 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
.PP
.Vb 1
\& { name => \*(AqSome One\*(Aq, address => \*(Aq123 Place Street\*(Aq }
.Ve
.PP
will become:
.PP
.Vb 2
\& { name => { Some => 1, One => 1 },
\&   address => { 123 => 1, Place => 1, Street => 1 } }
.Ve
.PP
All words get rank 1 because they're obvious guesses from a cracker's
point of view.
.PP
The rest of the logic is the same as for \f(CW\*(C`Dictionary\*(C'\fR.
.ie n .SS """feedback_warning"""
.el .SS "\f(CWfeedback_warning\fP"
.IX Subsection "feedback_warning"
The warnings for this class are very similar to those for
\&\f(CW\*(C`Dictionary\*(C'\fR, but they explicitly mention the field name. Warnings
look like:
.PP
.Vb 1
\& [\*(AqThe value of the [_1] field is easy to guess\*(Aq,\*(Aqaddress\*(Aq]
.Ve
.PP
so your localisation library can translate the warning and the field
name separately.
