This document provides a guide on testing Perl code with taint mode enabled to ensure data safety.

Example of Testing Code in Taint Mode


            #!/usr/bin/perl -T
            use strict;
            use warnings;

            # Simulating tainted input
            my $user_input = ;

            # Taint check: untainted data
            chomp($user_input);
            if ($user_input =~ /^[a-zA-Z0-9]+$/) {
                my $safe_input = $user_input; # Safe to use
                print "You entered a safe input: $safe_input\n";
            } else {
                die "Unsafe input detected!";
            }
