Python tkinter密码强度检查器gui

Question

我正在尝试创建一个密码强度检查器gui，检查密码的长度（超过8个字符）小写和大写字母，数字和特殊字符然后告诉你它是什么级别，弱，强等...然后它创建一个md5哈希并显示它，然后你可以将这个哈希存储在一个文本文件中。然后再次输入密码并从文本文件中验证（尚未为此完成任何代码）。

我设法实现了力量检查，哈希生成，登录到文件......我想。虽然如果没有输入密码，我希望代码返回'密码不能为空'，但它似乎没有在gui中工作。相同的代码在shell中运行。即使只使用3个字符作为密码，代码也永远不会返回'Very Weak'作为强度。

到目前为止，这是我的代码：

from tkinter import *
import hashlib
import os
import re

myGui = Tk()
myGui.geometry('500x400+700+250')
myGui.title('Password Generator')
guiFont = font = dict(family='Courier New, monospaced', size=18, color='#7f7f7f')


#====== Password Entry ==========
eLabel = Label(myGui, text="Please Enter you Password:   ", font=guiFont)
eLabel.grid(row=0, column=0)
ePassword = Entry(myGui, show="*")
ePassword.grid(row=0, column=1)



#====== Strength Check =======


def checkPassword():
    strength = ['Password can not be Blank', 'Very Weak', 'Weak', 'Medium', 'Strong', 'Very Strong']
    score = 1
    password = ePassword.get()

    if len(password) < 1:
        return strength[0]

    if len(password) < 4:
        return strength[1]

    if len(password) >= 8:
        score += 1

    if re.search("[0-9]", password):
        score += 1

    if re.search("[a-z]", password) and re.search("[A-Z]", password):
        score += 1

    if re.search(".", password):
        score += 1

    passwordStrength.set(strength[score])

passwordStrength = StringVar()
checkStrBtn = Button(myGui, text="Check Strength", command=checkPassword, height=2, width=25, font=guiFont)
checkStrBtn.grid(row=2, column=0)
checkStrLab = Label(myGui, textvariable=passwordStrength)
checkStrLab.grid(row=2, column=1, sticky=W)

#====== Hash the Password ======


def passwordHash():
    hash_obj1 = hashlib.md5()
    pwmd5 = ePassword.get().encode('utf-8')
    hash_obj1.update(pwmd5)
    md5pw.set(hash_obj1.hexdigest())

md5pw = StringVar()
hashBtn = Button(myGui, text="Generate Hash", command=passwordHash, height=2, width=25, font=guiFont)
hashBtn.grid(row=3, column=0)
hashLbl = Label(myGui, textvariable=md5pw)
hashLbl.grid(row=3, column=1, sticky=W)


#====== Log the Hash to a file =======


def hashlog():
    loghash = md5pw.get()

    if os.path.isfile('password_hash_log.txt'):
        obj1 = open('password_hash_log.txt', 'a')
        obj1.write(loghash)
        obj1.write("\n")
        obj1.close()

    else:
        obj2 = open('password_hash_log.txt', 'w')
        obj2.write(loghash)
        obj2.write("\n")
        obj2.close()

btnLog = Button(myGui, text="Log Hash", command=hashlog, height=2, width=25, font=guiFont)
btnLog.grid(row=4, column=0)

#====== Re enter password and check against stored hash ======
lblVerify = Label(myGui, text="Enter Password to Verify:   ", font=guiFont)
lblVerify.grid(row=5, column=0, sticky=W)

myGui.mainloop()

非常感谢任何帮助。感谢。

您拥有checkPassword函数的结果，其中密码小于4或1个字符，作为return语句返回。您没有为checkPassword的结果分配变量，因此在这两种情况下无法从函数接收数据。我建议更像：

from tkinter import *
import hashlib
import os
import re

myGui = Tk()
myGui.geometry('500x400+700+250')
myGui.title('Password Generator')
guiFont = font = dict(family='Courier New, monospaced', size=18, color='#7f7f7f')


#====== Password Entry ==========
eLabel = Label(myGui, text="Please Enter you Password:   ", font=guiFont)
eLabel.grid(row=0, column=0)
ePassword = Entry(myGui, show="*")
ePassword.grid(row=0, column=1)



#====== Strength Check =======


def checkPassword():
    strength = ['Password can not be Blank', 'Very Weak', 'Weak', 'Medium', 'Strong', 'Very Strong']
    score = 1
    password = ePassword.get()
    print password, len(password)

    if len(password) == 0:
        passwordStrength.set(strength[0])
        return

    if len(password) < 4:
        passwordStrength.set(strength[1])
        return

    if len(password) >= 8:
        score += 1

    if re.search("[0-9]", password):
        score += 1

    if re.search("[a-z]", password) and re.search("[A-Z]", password):
        score += 1

    if re.search(".", password):
        score += 1

    passwordStrength.set(strength[score])

passwordStrength = StringVar()
checkStrBtn = Button(myGui, text="Check Strength", command=checkPassword, height=2, width=25, font=guiFont)
checkStrBtn.grid(row=2, column=0)
checkStrLab = Label(myGui, textvariable=passwordStrength)
checkStrLab.grid(row=2, column=1, sticky=W)

#====== Hash the Password ======


def passwordHash():
    hash_obj1 = hashlib.md5()
    pwmd5 = ePassword.get().encode('utf-8')
    hash_obj1.update(pwmd5)
    md5pw.set(hash_obj1.hexdigest())

md5pw = StringVar()
hashBtn = Button(myGui, text="Generate Hash", command=passwordHash, height=2, width=25, font=guiFont)
hashBtn.grid(row=3, column=0)
hashLbl = Label(myGui, textvariable=md5pw)
hashLbl.grid(row=3, column=1, sticky=W)


#====== Log the Hash to a file =======


def hashlog():
    loghash = md5pw.get()

    if os.path.isfile('password_hash_log.txt'):
        obj1 = open('password_hash_log.txt', 'a')
        obj1.write(loghash)
        obj1.write("\n")
        obj1.close()

    else:
        obj2 = open('password_hash_log.txt', 'w')
        obj2.write(loghash)
        obj2.write("\n")
        obj2.close()

btnLog = Button(myGui, text="Log Hash", command=hashlog, height=2, width=25, font=guiFont)
btnLog.grid(row=4, column=0)

#====== Re enter password and check against stored hash ======
lblVerify = Label(myGui, text="Enter Password to Verify:   ", font=guiFont)
lblVerify.grid(row=5, column=0, sticky=W)

myGui.mainloop()
