=head1 NAME
CGI::Application::Plugin::Authentication::Driver::Filter::crypt - crypt Filter
=head1 METHODS
=head2 filter ( undef, $string [, salt ] )
This will generate a crypted string. The first parameter is always ignored,
since there is only one way to use the crypt function. You can pass in an
extra parameter to act as the salt.
my $filtered = $class->filter(undef, 'foobar'); # mQvbWI43eDCAk
-or-
my $filtered = $class->filter(undef, 'foobar', 'AA'); # AAZk9Aj5/Ue0E
=head2 check ( undef, $string, $crypted )
This will crypt the string, and compare it against the provided crypted string.
The first parameter is always ignored, since there is only one way to use the
crypt function.
if ($class->check(undef, 'foobar', 'mQvbWI43eDCAk')) {
# they match
}
