The "Small" Password Game

Puzzles

The password game is a web game where you will write a password as it says, but it has a twist, you have to follow some insanely stupid rules to complete the perfect password.

So in this kata you will have a bunch of rules and need to make a method that validates if a String satisfies them all.

Input
  • A String or empty String
  • The given String will not have blank spaces or line breaks
Output
  • A boolean which state if the password is strong enough to pass the game
Rules
  • The maximum lenght of the password is 50 characters
  • The minimum lenght of the password is 20 characters
  • The length of the password must be a prime number
  • Must have at least 1 lower case, 3 upper case letter and 1 special character
  • The addition of each of the digits in the password has to be at least 25
  • Must have the diminituve of a month
  • Must have today's date
  • 2 special characters can't be together
  • The length of the password must be inside the password
Clarifications
  • The months of the year for this kata are [jan, feb, mar, apr, may, jun, jul, aug, sep, oct, nov, dec]
  • The months may be in upper case, lower case or combined
  • The date inside the password will have the following format YYYYMMDD
  • The date numbers count as normal digits
  • The special characters for this kata are ['-', '.' , '_', '@', '#', '$', '&']
