Instructions
Your task is to create a password checker. A password checker validates a user's proposed password to ensure that it meets a set of requirements defined by the organization that controls access to the given resource.
For this exercise, the password requirements are:
- Must have 12 or more characters
- Must have at least one uppercase letter
- Must have at least one lowercase letter
- Must have at least one digit
- Must have at least one symbol in the set !@#$%^&*
Your solution must use a Result to encapsulate the success or failure status.
For the success case, the Result must convey the validated password as a string.
For the failure case, the Result must convey the rule that was violated in the failure case.
Note
For this exercise, the password checker will be simplistic -- it will indicate only when a single rule has been violated. A subsequent exercise will explore a more realistic password checker that can indicate when multiple rules have been violated at the same time.
1. Implement the checkPassword function
The checkPassword function checks the given password against the aforementioned rules. On failure, it indicates the rule that was violated by encapsulating one of the PasswordRule values within the result value.
checkPassword "abcdefghij5#"
// => Error MissingUppercaseLetter2. Implement the ``getStatusMessage` function
The getStatusMessage function returns a string containing a human-readable message indicating the meaning of the result returned from checkPassword.
getStatusMessage (Error MissingDigit)
// => "Error: does not have at least one digit"Password Checker
