Python Password Protection

Question

I am a beginner so if this question sounds stupid, please bear with me.

I am wondering that when we write code for username/password check in python, if it is not c

Answer 1

To protect data stored on the client machine, you have to encrypt it. Period.

If you trust an authorized user, you can use a password-based encryption key (many other answers on Stack Exchange address this), and hope that he is smart enough to protect his computer from malware.

If you don't trust the authorized user (a.k.a. DRM) you are just plain out of luck -- find another project.;-)

Answer 2

I have spend the last couple of days refining this and running it through password crackers and it seems to be holding up pretty strong.

Here is my code for you to look at:

import time
import os
import random
import string

passwordScore = 0

def optionOne():
    global passwordScore
    #Code for checking a password
    os.system('cls')
    print('Option One has been selected')
    password = input('Please type in your password here: ')

    #Password check begins
    if (len(password) > 7) and (password.isspace() == False):
        #Check for capitalisation
        for p in password:
            if p.isupper() == True:
                passwordScore += 1
            else:
                pass

        passwordScore += 2
        for s in string.punctuation:
            #Beginning test for special letters
            for p in password:
                if s == p:
                    passwordScore += 1
                else:
                    pass
    else:
        pass

    # Returning results to the user
    if passwordScore >= 5:
        print('Your password is safe enough to use')
        time.sleep(2)
    elif passwordScore == 3:
        print('We believe your password could be safer')
        time.sleep(2)
    else:
        print('Your password is not safe enough to use')
        print('using this password may place your data at risk')
        time.sleep(2)


def optionTwo():
    #Code for creating a password at random
    print('Option Two has been selected')
    chars = string.ascii_uppercase + string.ascii_lowercase + string.digits + string.punctuation
    size = random.randint(8, 12)
    newPassword = ''.join(random.choice(chars) for x in range(size))
    print(newPassword)

def start():
    print('Option 1: Check my passsword')
    print('Option 2: Create a password')
    option = input('Please chose your option here [ENTER]: ')

    if option == '1':
        #Option 1 has been selected
        return optionOne()
    elif option == '2':
        #Option 2 has been selected
        return optionTwo()
    else:
        #An error has occured
        print('You have not selected a valid option')
        time.sleep(1)
        os.system('cls')
        return start()


for i in range(1):
    start()

This should do the job for almost everything as long as you tweak it to your needs!!
