Weakling

Weakling is a simple prototype-based javascript plugin to measure the strength of a password.

I significantly modified Frane’s plugin called password_strength_meter
I didn’t want a percentage bar so I stripped that out, I refactored the helper to be more readable. It passes a hash instead of array for strength text Its supports locales.
