简单的加密算法

import hashlib
str = 'hello world'
bytestring = str.encode('UTF-8') # 生成bytes类型数据
m = hashlib.md5() # 产生MD5加密对象
m.update(bytestring) # 把产生的bytes加入到m对象中
a = m.hexdigest() # 生成密文
print(a)

加密算法的GUI实现

使用QtDesigner绘制GUI框架

如上图所示打开QtDesigner，并绘制如下图框架。

注意：上图框架中的文本框使用的是plainTextEdit。

将绘制好的.ui文件用PyUIC转换为.py文件。

功能实现代码如下：

import sys
from PyQt5 import QtCore, QtGui, QtWidgets
import hashlib
# 加密方式
encry_mode = {
 'md5': hashlib.md5,
 'sha1': hashlib.sha1,
 'sha224': hashlib.sha224,
 'sha256': hashlib.sha256,
 'sha384': hashlib.sha384,
 'sha512': hashlib.sha512,
 'sha3_224': hashlib.sha3_224,
 'sha3_256': hashlib.sha3_256,
 'sha3_384': hashlib.sha3_384,
 'sha3_512': hashlib.sha3_512,
}

 self.retranslateUi(Form)

 QtCore.QMetaObject.connectSlotsByName(Form)

 Form.setWindowTitle(_translate("Form", "加密算法"))
