使用Python计算文件和文本的多种Hash值

这篇文章主要为大家详细介绍了如何使用Python计算文件和文本的多种Hash值,文中的示例代码讲解详细,感兴趣的小伙伴可以跟随小编一起学习一下

本文将使用Python编写的GUI应用，具备文件拖拽功能，能够计算文件和文本的多种Hash值，包括MD5、SHA1、SHA224、SHA256、SHA384、SHA512以及CRC32。

具体界面效果如下

导入模块

import tkinter
from tkinter import *
import tkinter as tk
from tkinter.ttk import *
import tkinter.filedialog
import pyperclip
import windnd
import hashlib  
import sys
import zlib

简单框架

root = Tk()
root.title('贱工坊-Hash计算')  # 程序的标题名称
root.geometry("580x400+512+288")  # 窗口的大小及页面的显示位置
root.resizable(False, False)  # 固定页面不可放大缩小
root.iconbitmap("picture.ico")  # 程序的图标

为界面添加图片及要拖拽框架的指向位置

canvas = tkinter.Canvas(root, bg="#ebebeb", height=400, width=700, borderwidth=-3)  # 创建画布
canvas.pack(side='top')  # 放置画布（为上端）
try:
    image_file = tkinter.PhotoImage(file="./Along.png")  # 加载图片文件
    canvas.create_image(0, 0, anchor='nw', image=image_file)  # 将图片置于画布上
except:
    pass
photo = PhotoImage(file="./ZCY.png")
theLabel = Label(root,image=photo)
theLabel.place(x=450,y=20)

多行文本框，一个是输入，一个是输出

ScrolledText = Text(root, width=60, height=12)
ScrolledText.place(x=1,y=1)

ScrolledText_file = Text(root, width=60, height=12)
ScrolledText_file.place(x=1,y=236)

用来转换文件hash
