Question

我差不多完成了我的gui。这应该检查输入的密码的强度，即它有多长，大小写，特殊字符等... 将该密码哈希到md5哈希中，将其存储在文本文件中。然后用户将重新输入密码，将进行重新散列，然后检查文本文件以查看该散列是否在那里。但是我似乎无法正确地重新输入密码并使用它来检查文件。

我的完整代码：

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')
guiFont2 = font1 = dict(family='Courier New, monospaced', size=18, color='9400d3')


#====== 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) == 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, font=guiFont2)
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, font=guiFont2)
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 ======


def verifyHash():
    hashinput = vHash.get()
    hashobj2 = hashlib.md5(hashinput.encode('utf-8')).hexidigest()

    with open('password_hash_log.txt') as obj3:
        for line in obj3:
            line = line.rstrip()
            if line == hashobj2:
                output.set("Password Match")
            else:
                output.set("Passwords do not match try again")


output = StringVar()
lblVerify = Label(myGui, text="Enter Password to Verify:   ", font=guiFont)
lblVerify.grid(row=5, column=0, sticky=W)
vHash = Entry(myGui, show="*")
vHash.grid(row=5, column=1)
vBtn = Button(myGui, text="Verify Password", command=verifyHash, height=2, width=25, font=guiFont)
vBtn.grid(row=6, column=0)
vLbl = Label(myGui, textvariable=output, font=guiFont2)
vLbl.grid(row=6, column=1, sticky=W)

myGui.mainloop()

我已经接近完成了我需要做的事情，所以非常感谢任何帮助。

在我之前的例子中，没有通过hexidigest传递任何东西来产生哈希。我修改了代码的最后部分，gui现在按计划工作。

新代码：

def verifyHash():

    hash_obj2 = hashlib.md5()
    pwmd52 = vHash.get().encode('utf-8')
    hash_obj2.update(pwmd52)
    md5pw2.set(hash_obj2.hexdigest())

    with open('password_hash_log.txt') as obj3:
        for line in obj3:
            line = line.rstrip()
            if line == md5pw2.get():
                output.set("Password Match")
            else:
                output.set("Passwords do not match try again")

md5pw2 = StringVar()

现在md5pw2是Hashed代码并验证Hash接受并检查文本文件的每一行以查看该Hash是否在那里，然后如果找到它则返回密码匹配。
