简单的加密算法
import hashlibstr = \'hello world\'
bytestring = str.encode(\'UTF-8\') # 生成bytes型别资料
m = hashlib.md5() # 产生MD5加密物件
m.update(bytestring) # 把产生的bytes加入到m物件中
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
如上图所示开启QtDesigner，并绘制如下图框架。
注意：上图框架中的文字框使用的是plainTextEdit。
将绘制好的.ui档案用PyUIC转换为.py档案。
功能实现程式码如下：
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,
}
