SYNOPSIS


            

              
              
my $pwdm = Data::Password::Meter->new(28);
# Check a password

}

DESCRIPTION

Check the strength of a password. The scoring is based on Passwordmeter by Steve Moitozo.

ATTRIBUTES

err


            

              
              
print $pwdm->err;

The error code of the last check. Returns a false value, if the last check was successful.

errstr


            

              
              
print $pwdm->errstr;
print $pwdm->errstr(4);

The error string of the last check, or, in case an error code is passed, the corresponding message. Returns an empty string, if the last check was successful.

score


            

              
              
print $pwdm->score;

The score of the last check.

threshold


            

              
              
print $pwdm->threshold;
$pwdm->threshold(28);

The scoring threshold, the determining factor when a password is too weak. Every password that is below this threshold is considered weak. Defaults to a score of 25.

METHODS

new


            

              
              
my $pwd = Data::Password::Meter->new(28);

Constructs a new password check object. Accepts an optional value for the threshold.

strong


            

              
              
if ($pwdm->strong('mypassword')) {
  print 'This password is strong!';
}
else {
  print 'This password is weak!';
};

Checks a password for strength. Returns a false value in case the password is considered to be weak.
