zxcvbn - Low-Budget Password Strength Estimation

  •    CoffeeScript

zxcvbn is a password strength estimator inspired by password crackers. Through pattern matching and conservative estimation, it recognizes and weighs 30k common passwords, common names and surnames according to US census data, popular English words from Wikipedia and US television and movies, and other common patterns like dates, repeats (aaa), sequences (abcd), keyboard patterns (qwertyuiop), and l33t speak.Consider using zxcvbn as an algorithmic alternative to password composition policy — it is more secure, flexible, and usable when sites require a minimal complexity score in place of annoying rules like "passwords must contain three of {lower, upper, numbers, symbols}".

password-strength - Calculates the entropy of a password

  •    Javascript

Password Strength is a library that calculates the relative strength of a password. This is accomplished by using several techniques. Primarily this relies on letter trigraphs, which check each set of 3 characters in a given password. More information on the trigraph calculations is available. This also calculates the entropy bits based on Claude Shannon's technique on determining the number of bits required to represent a set of characters and multiplying it by the length of the password. There is also a check to see if a password is contained in a list of common passwords. There is a wonderful demo page where you can test out the technology yourself.
