But how does the palindrome rule work with “password must start with ‘cat’” and “password must end with ‘dog’”? It seems impossible to satisfy these three. Having the conditions contradict each other serves as a proof that it’s impossible to create a password; I thought this information shouldn’t be revealed to the user. Looks like there is already an issue about it: https://github.com/troyhunt/password-purgatory-api/issues/45

You can check in their GitHub repo [1] the list of reasons to reject your password (classified by level of "InfuriationLevel"). Some examples: 'Password must contain at least 1 primary Simpsons family character' 'Password must contain at least 1 Nordic character' 'Password must contain at least 1 Greek character' 'Password must contain at least 1 primary Griffin family character' 'Password must contain at least one emoticon' 'Password when stripped of non-numeric characters must be a number divisible by 3' [1] https://github.com/troyhunt/password-purgatory-api/blob/mast...

You can find the in-progress list of checks in this source file: https://github.com/troyhunt/password-purgatory-api/blob/mast... It includes such gems as requiring the sum of all digits in the password to be divisible by 3, requiring passwords to contain Simpsons/Family Guy character names, emoticons, ending with “dog”, and all sorts of other craziness. Can’t wait to see his results.
