用户界面-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，它检查密码的长度（超过8个字符）小写字母、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，并从文本文件中进行验证（尚未为此执行任何代码）。

我已经设法实现了强度检查、哈希生成、日志到文件。。。。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"，但它似乎在gui中不起作用。相同的代码在shell中工作。即使只有3个字符用作密码，该代码也从不返回"Very Weak"作为强度。

这是我到目前为止的代码：

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()

任何帮助都将不胜感激。谢谢

您得到了checkPassword函数的结果，其中密码少于4或1个字符，并作为返回语句返回。您并没有为checkPassword的结果分配变量，所以在这两种情况下，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)
