Password entropy calculation based on the Russian language dictionary. Implementations?

Question

JavaScript

Are there ready-made implementations for evaluating entered passwords on a non-English dictionary base. Moreover, taking into account that 50/50 is the use of Russian keys in the Glian layout? Of the implementations, js is convenient, but the main thing is the essence of the algorithm.

Answer 1

What is the problem with writing such an algorithm? You get a string, then
1) If the password is > 8 characters - continue (put 1 stick of complexity out of 4), no - discard
2) If the password contains numbers - add a stick
3) There is at least one capital - more + 1
4) If the characters , like [email protected]#$%^... - more + 1
Next, we check the resulting number and, depending on its value, issue or not issue an error.
Everything goes through a banal search for a character in a string

Answer 2

Interleaving groups of character sets.
Then, we multiply the prime numbers going in order in the number of alternations of these groups.
