CS50 Final Project: Password Generator

Description

A simple terminal-based password generator that gives you a fair bit of customisation. You can also make a passphrase with this one.

Getting Started

To get started, run project.py

Contains

Interface

Where you can call the password generators, to provide a password/passphrase for your use.

main() function

• Contains a welcome and farewell message. A while loop that gets and provides your password, with another prompt to end the program after generation, or to end it prematurely.

Constants

• Contains all the CONSTANTS that I've factored out to use across multiple files.

Exceptions

• QuitCommand, meant to signal that the user wants to quit the program.
• InvalidInputError, meant to signal that an input has an invalid value.
  • InvalidLengthError, meant to signal that an input has an invalid length.
  • InvalidTypeError, meant to signal that an input has an invalid type.

Password Generator

Functions grouped according to their categories.

Helper functions

• my_input() replaces the use of input() to handle quitting on command. Used to raise QuitCommand Exception.
• validate_length(): Provide simple input validation for password/passphrase length for get_valid_length().
• get_valid_length(): Gets the valid length from the user according to access_key_range.
• get_character_pool(): Asks the user for characters to include in their password and include them into the character pool.
• get_separator(): Gets a simple separator up to 3 characters in length. Defaults to "_".
• get_random_uppercase_flag(): Gets flags from the user for the Random Capitalisation feature for passphrases.
• randomly_capitalise(): Randomly capitalises each word according to get_random_uppercase_flag().

Main functions

• generate_password(): Prompts the user for features to include in their password and provides them with one.
• generate_passphrase(): Prompts the user for features to include in their passphrase and provides them with one.
• get_access_key(): Prompts the user to choose between generating a password and a passphrase.

Entry Point

• Contains main() that runs only if we are running the library itself. Right now it is the same as main() in password_generator.py.

Tests

• Contains some tests, not fully comprehensive as I do not know how to test password generation.
• Therefore it only contains length validation checks
• Uses pytest with parametrisation
