Password Generator
Crafting a Password Strength Checker with Python
In today’s digital landscape, where cybersecurity threats abound, protecting our online accounts with strong passwords is paramount. Let’s explore how Python can empower us to build a robust password strength checker, enabling us to bolster our digital defenses. This project was created in about 3 hours so it shows that anyone can make one of these password checkers with their own criteria to help evaluate their passwords.
Password Strength Criteria
- Length: Longer passwords are generally more secure.
- Complexity: Including a mix of uppercase letters, lowercase letters, digits, and special characters adds complexity.
- Avoidance of Common Patterns: Avoiding predictable patterns or dictionary words enhances security.
- Absence of Repeating Characters: Limiting repeating characters mitigates vulnerabilities.
Building the Password Strength Checker
We’ll break down our Python code into multiple snippets, each focusing on a specific aspect of the password strength checker.
Evaluating Length

def length_score(password):
return min(len(password)) // 4, 3)
Here we evaluate the length of the password and make sure that it doesnt return a value that is less then 8 characters.
Evaluating Complexity

def complexity_score(password):
categories = {'lower': False, 'upper': False, 'digit': False, 'special': False}
for char in password:
if char.islower():
categories['lower'] = True
elif char.isupper():
categories['upper'] = True
elif char.isdigit():
categories['digit'] = True
elif char in string.punctuation:
categories['special'] = True
return sum(categories.values())
These where some of the ways that I evaluated different aspects that are ment to go into the password to make sure that it conatins all of the requirements that most website passwords require such as a special character and capitlizeation.
Final Score and Interpretation

def password_strength(password):
length = length_score(password)
complexity = complexity_score(password)
final_score = length + complexity
if final_score <= 1:
return "Weak"
elif final_score <= 3:
return "Moderate"
elif final_score <= 5:
return "Strong"
else:
return "Very Strong"
This was the bounds that I used to help interperate the number of points that was assigned to the password that was generated.
Conclusion
By breaking down the password strength checker into manageable code snippets, we gain clarity and maintainability in our implementation. With Python’s flexibility and expressiveness, we empower ourselves to fortify our online security effectively. Remember, a strong password is a cornerstone of digital safety, so let’s wield the power of Python to safeguard our digital identities. There are many ways to improve this project such as adding a way to input your current password and make changes to it.
