0x00 介绍
培根密码实际上就是一种替换密码，根据所给表一一对应转换即可加密解密
它的特殊之处在于：可以通过不明显的特征来隐藏密码信息，比如大小写、正斜体等，只要两个不同的属性，密码即可隐藏
0x01 代码实现
脚本很简单，就是建立对应关系，对密文，或者明文进行相应的替换即可
需要注意的是输入的都应该是全小写字母或全大写字母，在脚本里也有说明
python脚本如下：
# coding:utf8
import re
alphabet = ['a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z']
first_cipher = ["aaaaa","aaaab","aaaba","aaabb","aabaa","aabab","aabba","aabbb","abaaa","abaab","ababa","ababb","abbaa","abbab","abbba","abbbb","baaaa","baaab","baaba","baabb","babaa","babab","babba","babbb","bbaaa","bbaab"]
second_cipher = ["aaaaa","aaaab","aaaba","aaabb","aabaa","aabab","aabba","aabbb","abaaa","abaaa","abaab","ababa","ababb","abbaa","abbab","abbba","abbbb","baaaa","baaab","baaba","baabb","baabb","babaa","babab","babba","babbb"]
def encode():
upper_flag = False # 用于判断输入是否为大写
string = raw_input("please input string to encode:\n")
if string.isupper():
upper_flag = True
string = string.lower()
e_string1 = ""
e_string2 = ""
for index in string:
for i in range(0,26):
if index == alphabet[i]:
e_string1 += first_cipher[i]
e_string2 += second_cipher[i]
break
if upper_flag:
e_string1 = e_string1.upper()
e_string2 = e_string2.upper()
print "first encode method result is:\n"+e_string1
print "second encode method result is:\n"+e_string2
return
def decode():
upper_flag = False # 用于判断输入是否为大写
e_string = raw_input("please input string to decode:\n")
if e_string.isupper():
upper_flag = True
e_string = e_string.lower()
e_array = re.findall(".{5}",e_string)
d_string1 = ""
d_string2 = ""
for index in e_array:
for i in range(0,26):
if index == first_cipher[i]:
d_string1 += alphabet[i]
if index == second_cipher[i]:
d_string2 += alphabet[i]
if upper_flag:
d_string1 = d_string1.upper()
d_string2 = d_string2.upper()
print "first decode method result is:\n"+d_string1
print "second decode method result is:\n"+d_string2
return
if __name__ == '__main__':
print "\t\tcoding by qux"
while True:
print "\t*******Bacon Encode_Decode System*******"
print "input should be only lowercase or uppercase,cipher just include a,b(or A,B)"
print "1.encode\n2.decode\n3.exit"
s_number = raw_input("please input number to choose\n")
if s_number == "1":
encode()
raw_input()
elif s_number == "2":
decode()
raw_input()
elif s_number == "3":
break
else:
continue0x02 不足
脚本的提示是英语，如果想改的话，在每个输出的地方把输出的字符串编码转一下就可以了，比如:
print("你好".decode("utf-8").encode("gbk"))
感觉没什么必要……
