PasswordChecker
Purpose
PasswordChecker is a Python program that analyzes how strong a user's password is by performing several checks. These checks include:
- Checking if the user's password has been exposed in HaveIBeenPwned's data breaches
- Verifying that the password meets a certain length requirement
- Calculating the percentage of characters in the password that belong to different character types (such as lowercase/uppercase letters, numbers, and symbols)
- Highlighting any characters that occur too frequently in the password
- Calculating the password's entropy, which is a measure of how difficult the password would be for an attacker to guess
- Generating a new, strong password for the user to use if desired.
