in reply to Efficient way to verify scalar contents

Your "Do it yourself" approach can be simplified by testing the content before the length.
use strict; use warnings; sub is_pw_valid { local $_ = $_[0]; return !(/[a-z]/ && /[A-Z]/) ? length >= 20 : !/\d/ ? length >= 16 : !/[\x21-\x2F\x3A-\x40\x5B-\x60\x7B-\x7E]/ ? length >= 12 : length >= 8 ; }

UPDATE: Corrected error in regex for special characters and added (below) a less terse version of the same logic

sub is_pw_valid { my $password = $_[0]; my $MixedCase = qr/(:? [a-z].*[A-Z]) | (:? [A-Z].*[a-z] )/x; my $Digit = qr/\d/; my $special = qr/[\x21-\x2F\x3A-\x40\x5B-\x60\x7B-\x7E]/; my $min_length; if ($password !~ $MixedCase) {$min_length = 20} elsif ($password !~ $Digit) {$min_length = 16} elsif ($password !~ $special) {$min_length = 12} else {$min_length = 8} + my $is_OK = ( length($password) >= $min_length ); return $is_OK; }
