7. jQuery-Encoder

8. ChronoStrength
It is a password strength checking plugin. However, rather than just saying “Too Weak” or “Strong”, which don’t really mean much, ChronoStrength displays how long it would take a regular desktop PC to crack the password using a brute-force attack. Seeing that their password would only take 30 seconds to crack might convince people to choose a more secure one!
