Authen::Passphrase::RejectAll - reject all passphrases
=head1 SYNOPSIS
use Authen::Passphrase::RejectAll;
$ppr = Authen::Passphrase::RejectAll->new;
$ppr = Authen::Passphrase::RejectAll
->from_crypt("*");
$ppr = Authen::Passphrase::RejectAll
->from_rfc2307("{CRYPT}*");
if($ppr->match($passphrase)) { ...
$passwd = $ppr->as_crypt;
$userPassword = $ppr->as_rfc2307;
=head1 DESCRIPTION
An object of this class is a passphrase recogniser that accepts any
passphrase whatsoever. This is a subclass of L<Authen::Passphrase>, and
this document assumes that the reader is familiar with the documentation
for that class.
This type of passphrase recogniser is obviously of no use at all in
controlling access to any resource. Its use is to permit a resource
to be completely inaccessible in a system that expects some type of
passphrase access control.

=head1 CONSTRUCTORS
=over
=item Authen::Passphrase::RejectAll->new
Returns a reject-all passphrase recogniser object. The same object is
returned from each call.
=cut
{
my $singleton = bless({});
sub new { $singleton }
}
=item Authen::Passphrase::RejectAll->from_crypt(PASSWD)
Returns a reject-all passphrase recogniser object. The same object is
returned from each call. The argument, a crypt string, must be between
one and twelve (inclusive) characters long and must not start with "B<$>".
=cut
sub from_crypt {
my($class, $passwd) = @_;
if($passwd =~ /\A[^\$].{0,11}\z/s) {
$passwd =~ /\A[!-#\%-9;-~][!-9;-~]{0,11}\z/
or croak "malformed reject-all crypt data";
return $class->new;
}
return $class->SUPER::from_crypt($passwd);
}
=item Authen::Passphrase::RejectAll->from_rfc2307(USERPASSWORD)
Generates a new reject-all passphrase recogniser object from an RFC
2307 string. The string must consist of "B<{CRYPT}>" (case insensitive)
followed by an acceptable crypt string.

=head1 METHODS
=over
=item $ppr->match(PASSPHRASE)
=item $ppr->as_crypt
=item $ppr->as_rfc2307
These methods are part of the standard L<Authen::Passphrase> interface.
The L</match> method always returns false.
