Strong Passwords Need Entropy
Password entropy and strength checker
Description
Whether a password is long or varied enough is hard to judge by feel. Strong Passwords Need Entropy (SPNE) computes its entropy and estimates how long it would take to crack at different attack speeds, so strength is obvious at a glance.
It also generates passwords by rule and can compute SHA-256, SHA-384 and SHA-512 hashes. It is a tiny tool under 1 MB that needs no installation.
Entropy calculation:shows entropy and strength grade live.
Crack time estimate:estimates minutes to years at different guessing speeds.
Password generation:generate random passwords by rule, with pronounceable and poetry aids to remember them.
Hashes and conversion:outputs SHA hashes and converts to hex or Base64.
