I don't know what you mean by "secure", but for counting characters length is what you need. Don't use split, it works but it does a lot more than is really needed to count chars in a string, for larger texts it can be a big overkill. But if you're serious about making sure that your users are choosing hard to guess passwords, use Crypt::Cracklib, Perl interface to Alec Muffett's Cracklib: http://search.cpan.org/search?dist=Crypt-Cracklib Cracklib tests potential passwords and rejects those which could be easy to guess using the most common password cracking techniques. If you only check string length then someone can use something like abcdefgh or a word from dictionary which can be long but very easy to guess.
