Password Validator

Background

NIST recently updated their Digital Identity Guidelines in June 2017. The new guidelines specify general rules for handling the security of user supplied passwords. Previously passwords were suggested to have certain composition rules (special characters, numbers, etc.), hints and expiration times. Those have gone out the window and the new suggestions are as follows: Passwords MUST

1. Have an 8 character minimum
2. AT LEAST 64 character maximum
3. Only allow printable ASCII characters and spaces
4. Not be a common password

Project

A program to detect if a password meets these requirements.

1. Have at least 8 Character

2. Can have 64 character maximum

3. Allowed only ASCII characters

4. Check not a common password

Program takes a file of newline delimited common passwords to check if a password is in that file and print invalid passwords to the command line and print * for any unprintable character
