That's a very unsafe way of doing things! You should be calling encrypt once, not once per line. 

encrypt(join("\n", @$input), $key)

I do get garbage at character 32 (or thereabouts, I didn't look closely) when I use your version. I didn't spend any time finding out why because it goes away if you encode once as I urged you to do above. 

...

my ($action, $file, $key) = @ARGV;

my $input;
{
   open(my $fh, '<', $file)
      or die("Can't open $file: $!\n");
   binmode($fh);
   local $/;
   $input = <$fh>;
}

if ($action eq '-e') {
   print encrypt($input, $key);
} else {
   print decrypt($input, $key);
}
