ayit期末设计刚好密码学的和信息管理的都可以用rsa算法于是就写了一份信息管理的需要有界面所以使用了pyqt5来做界面

Python 复现RSA算法

环境

首先python就不说了吧

如果你需要做界面就安装pyqt5和pyqt5-tools如果不需要就可以不安装

我是用的开发软件是pycharm

带Gui版本

信息管理需要带Gui的版本，其实最初版本是没有带Gui的

安装

安装pyqt5

pip install PyQt5

安装pyqt5-tools

pip install pyqt5-tools

然后在pycharm中配置外部工具 Qt-Designer可视化编辑界面工具和 pyuic5 .ui -> .py工具

Qt-Designer配置

工具设置 ->程序位置 ~\AppData\Roaming\Python\Python311\site-packages\qt5_applications\Qt\bin\designer.exe

工作目录 $FileDir$

pyuic5

工具设置 ->程序位置 AppData\Roaming\Python\Python311\Scripts\pyuic5.exe

实参 $FileName$ -o $FileNameWithoutExtension$.py

工作目录 $FileDir$

代码

main函数

import sys
import Gui
from PyQt5.QtWidgets import QApplication, QMainWindow

if __name__ == "__main__":
    # 实例化，传参
    app = QApplication(sys.argv)
    mainWindow = QMainWindow()
    ui = Gui.Ui_MainWindow()
    ui.setupUi(mainWindow)
    mainWindow.show()
    sys.exit(app.exec_())

Gui界面

其实大部分是使用工具直接生成的界面，主要编写部分是对行为的定义和槽函数的编写如果你需要自定义可以自己更改槽函数部分
