Description

Welcome to Py_Pass_Gen, a simple program that makes passwords and saves them to a file.

I enjoy writing password programs when learning new languages.

Here is the repo for the project.

Goals

1. Automatically create a file to store the passwords.
2. Continue creating passwords until the user chooses to exit.
3. Provide a unique combination of upper chars, lower case chars, and special chars.
4. User entered password name and length.
5. Save completed passwords to the file.

Dependencies

If you want to run tests.py pip install -r dev-requirements.txt

Password Module:

This section uses the random module to generate four different lists.

Valid characters

Each list is made of random choices from four different categories:

• UPPER CASE (A - Z)
• LOWER CASE (a - z)
• INTEGER (0 - 9)
• SYMBOLS (#, $, %, &)

Lists of ASCII Integers

The lists are populated by a range of ASCII Integers based on their category.

• UPPER CASE (67 - 90)
• LOWER CASE (97 - 122)
• INTEGER (48 - 57)
• SYMBOLS (35, 36, 37, 38)

charListUpper = list(range(67, 91))

charListLower = list(range(97, 123))

intList = list(range(48, 58))

symList = list(range(35, 39))

Probability

The UPPER CASE and LOWER CASE lists are longer than the INTEGER and SYMBOLS lists, so we need a way to keep the selections even between the four lists.

Character pool

To even the probability of a pick from each list, a second list of random items from the four parent lists is created to form a password pool that the password will be drawn from.

passwordList += [upperPick, lowerPick, intPick, symPick]

Password creation

A third passwordList is returned of random characters from each of the previous lists.

password += chr(random.choice(passwordList))
