✨费纳姆密码：加解密都需要密钥，以二进制形式表示的密码。（密钥多是一次性的，称位一次性密码本）

加密过程：

✨杰弗逊转轮加密：需要密钥并用很多行乱序英文字母表示密文的密码。首先要将密文按密钥顺序进行调整，再根据密文顺序整每行字符串即可得到明文。

方法1：

除了每行第一个字母组成的，依次往后向下寻找有意义的字符串，直到找到为止！！！

方法2：

import re
PasswordList = '''
1: < ZWAXJGDLUBVIQHKYPNTCRMOSFE <
2: < KPBELNACZDTRXMJQOYHGVSFUWI <
3: < BDMAIZVRNSJUWFHTEQGYXPLOCK <
4: < RPLNDVHGFCUKTEBSXQYIZMJWAO <
5: < IHFRLABEUOTSGJVDKCPMNZQWXY <
6: < AMKGHIWPNYCJBFZDRUSLOQXVET <
7: < GWTHSPYBXIZULVKMRAFDCEONJQ <
8: < NOZUTWDCVRJLXKISEFAPMYGHBQ <

12: < LVNCMXZPQOWEIURYTASBKJDFHG <
13: < JZQAWSXCDERFVBGTYHNUMKILOP <
'''
ciphertext = "UOFJLBLSXJPJY"  # 存放密文
content = re.findall(r'<(.*?)<', PasswordList, re.S)  # 匹配所有的密码表字符串
key = [2, 3, 7, 5, 13, 12, 9, 1, 8, 10, 4, 11, 6]   # 密钥
list = []   # 定义空列表list，和空串ans
ans = ""
for i in range(13):index = content[key[i]-1].index(ciphertext[i])list.append((index))
for i in range(0, 26):flag = ""for j in range(13):flag += content[key[j]-1][(list[j]+i) % 26]print(flag)

 

 从出来的结果找出有意义的那串字符即为明文！！！
