凯撒密码

md5

 1 # 由于MD5模块在python3中被移除
 2 # 在python3中使用hashlib模块进行md5操作
 3 
 4 import hashlib
 5 
 6 # 待加密信息
 7 str = input('请输入要加密的字符串:')
 8 
 9 # 创建md5对象
10 m = hashlib.md5()
11 
12 # Tips
13 # 此处必须encode
14 # 若写法为m.update(str)  报错为： Unicode-objects must be encoded before hashing
15 # 因为python3里默认的str是unicode
16 # 或者 b = bytes(str, encoding='utf-8')，作用相同，都是encode为bytes
17 b = str.encode(encoding='utf-8')
18 m.update(b)
19 str_md5 = m.hexdigest()
20 # md5在线解密网站：https://cmd5.com/
21 
22 print('MD5加密前为 ：' + str)
23 print('MD5加密后为 ：' + str_md5)
24 
25 # 另一种写法：b‘’前缀代表的就是bytes
26 # str_md5 = hashlib.md5(b'this is a md5 test.').hexdigest()
27 # print('MD5加密后为 ：' + str_md5)
