各种编码及密码原理(边积累边更新)

也有看过很多大佬的总结，本来想转载一个过来，但还是决定把自己用过的亲自总结一遍，欢迎指教。

注意：

1）字母矩阵注意结果可能在一行中，可能在一列中，也可能有其余情况，需要仔细观察，一般拼接后是单词

2）字母密码需要注意顺序：正序、倒序、根据格式拼接

1、凯撒加密

古典密码之一，原理：移位，一般是ASCII码移位。

很多在线工具和软件都只进行26个字母的移位，不处理符号，且在26个字母之间循环移位(Z移位变成A)。

例：aZZg/x\ZbavpZiEZp+n)o+用凯撒之后为

bAAh/y\AcbwqAjFAq+o)p+
cBBi/z\BdcxrBkGBr+p)q+
dCCj/a\CedysClHCs+q)r+

sRRy/p\RtsnhRaWRh+f)g+
tSSz/q\SutoiSbXSi+g)h+
uTTa/r\TvupjTcYTj+h)i+
vUUb/s\UwvqkUdZUk+i)j+
wVVc/t\VxwrlVeAVl+j)k+
xWWd/u\WyxsmWfBWm+k)l+
yXXe/v\XzytnXgCXn+l)m+
zYYf/w\YazuoYhDYo+m)n+
aZZg/x\ZbavpZiEZp+n)o+

可以看到只在大小写字母间循环移位，对符号不予理睬，但有的题目是需要符号移位的，下面给出一个ASCII范围在33-126之内的循环移位脚本(94种结果)：

代码转自：https://blog.csdn.net/dongyanwen6036/article/details/76447628# 实现33-126ASCII能打印的字符循环平移
# 和通常凯撒加密不同注意
def change(c, i):num = ord(c)if (num >= 33 and num <= 126):num = 33 + (num + i - 33) % (94)  # 126-33=93return chr(num)def kaisa_jiAmi(string, i):string_new = ''for s in string:string_new += change(s, i)print(string_new)return string_new# 本题有种暴力解密感觉
def kaisa_jiEmi(string):for i in range(0, 94):print('第' + str(i + 1) + '种可能:', end='   ')# 区别在于 string 是该对象原本就是字符串类型, 而 str()则是将该对象转换成字符串类型。kaisa_jiAmi(string, i)# 你要知道input输入的数据类型都是string
def main():print('请输入操作，注意不是平常26种:')choice = input('1:恺撒加密,2:凯撒穷举解密.请输入1或2：')if choice == '1':string = input('请输入需要加密字符串： ')num = int(input('请输入需要加密的KEY： '))kaisa_jiAmi(string, num)elif choice == '2':string = input('请输入需要解密字符串： ')kaisa_jiEmi(string)else:print('输入错误，请重试')main()if __name__ == '__main__':main()

2、栅栏加密

古典密码之一，原理：就是把要加密的明文分成N个一组，然后把每组的第1个字分别连起来，然后再把每个组按顺序依次连接，形成一段无规律密文。

所以一般密文个数不是质数

例：2栏的栅栏密码。

比如明文：THERE IS A CIPHER

去掉空格后变为：THEREISACIPHER

两个一组，得到：TH ER EI SA CI PH ER

先取出第一个字母：TEESCPE

再取出第二个字母：HRIAIHR

连在一起就是：TEESCPEHRIAIHR

解码用工具就可以。

3、摩斯电码

这个都很熟悉，就是利用摩斯电码表来翻译明文和密文

4、维吉尼亚加密(超级凯撒)(密码表+明文+密钥)(对称加密)

维吉尼亚密码是以凯撒加密为基础衍生出来的加密方法，利用了26个字母经过凯撒加密组成的密码表来进行加密解密。

A -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
B -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 A
C -C D E F G H I J K L M N O P Q R S T U V W X Y Z A B
D -D E F G H I J K L M N O P Q R S T U V W X Y Z A B C
E -E F G H I J K L M N O P Q R S T U V W X Y Z A B C D
F -F G H I J K L M N O P Q R S T U V W X Y Z A B C D E
G -G H I J K L M N O P Q R S T U V W X Y Z A B C D E F

O -O P Q R S T U V W X Y Z A B C D E F G H I J K L M N
P -P Q R S T U V W X Y Z A B C D E F G H I J K L M N O
Q -Q R S T U V W X Y Z A B C D E F G H I J K L M N O P
R -R S T U V W X Y Z A B C D E F G H I J K L M N O P Q
S -S T U V W X Y Z A B C D E F G H I J K L M N O P Q R
T -T U V W X Y Z A B C D E F G H I J K L M N O P Q R S
U -U V W X Y Z A B C D E F G H I J K L M N O P Q R S T
V -V W X Y Z A B C D E F G H I J K L M N O P Q R S T U
W -W X Y Z A B C D E F G H I J K L M N O P Q R S T U V
X -X Y Z A B C D E F G H I J K L M N O P Q R S T U V W
Y -Y Z A B C D E F G H I J K L M N O P Q R S T U V W X
Z -Z 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
这就是密码表，举个例子：

明文BLOCKCIPHERDESIGNPRINCIPLE，密钥COMPUTER，我们要对明文进行加密。

明文第一个是B，密钥第一个是C，于是就找在C开头的行中和B(第一行的字母)同一列的字母：D。

明文第二个是L，密钥第二个是O，于是就找在O开头的行中和L(第一行的字母)同一列的字母：Z。

依次查找(循环使用密钥)，加密结果：DZAREVMGJSDSYLMXPDDXHVMGNS

这里附上维吉尼亚密码的解密脚本：

代码转自：https://blog.csdn.net/dongyanwen6036/article/details/76716373# encoding: utf-8def VigenereEncryto(min,key):MinLen=len(min)#明文长度KeyLen=len(key)#密钥长度(q,r)=divmod(MinLen,KeyLen)#q商 r余数out=""#完整映射密钥的加密for i in range(0,q):for j in range(0,KeyLen):#谈谈核心代码理解结合实例#密钥:R#明文:T#密文:K：#(R-A)%26+A和（T-A）%26+A得到K===>（T-A+R-A）%26+A#（T-A）%26+A就是以A开头第T个元素，A与R列对齐意思即是，(R-A)%26+A就是以R头字母表，R之后的第T-A元素c=int((ord(min[i*KeyLen+j])-ord('A')+ord(key[j])-ord('A'))%26+ord('A'))out+=chr(c)#残余映射密钥加密for i in range(0,r):c=int((ord(min[q*KeyLen+i])-ord('A')+ord(key[i])-ord('A'))%26+ord('A'))out+=chr(c)return outdef VigenereDecryto(anwen,key):AnLen=len(anwen)#明文长度KeyLen=len(key)#密钥长度(q,r)=divmod(AnLen,KeyLen)#q商 r余数out=""#完整映射密钥的加密for i in range(0,q):for j in range(0,KeyLen):#已知暗文位置减去A,加上Z减去key的位置就是，A到明文长度#K-A+1   + Z-R===〉T-Ac=int((ord(anwen[i*KeyLen+j])-ord('A')+1+ord('Z')-ord(key[j]))%26+ord('A'))out+=chr(c)#残余映射密钥加密for i in range(0,r):c=int((ord(anwen[q*KeyLen+i])-ord('A')+1+ord('Z')-ord(key[i]))%26+ord('A'))out+=chr(c)return out

5、PlayFair加密(明文+密钥)(对称加密)

PlayFair使用的是5*5矩阵以及明文每两个一组的分组来加密的。

详细解释及使用参考：https://blog.csdn.net/zz_Caleb/article/details/86698112

6、盲文密码

根据盲文进行转换加密

7、甲子年加密

这个应该是比较少见的，见过一个利用甲子年进行ASCII码转换的。

8、ASCII码运算加密

通过对ASCII码进行各种运算进行加密。

如：

97 102 90 95 114 57 86 89 102 83 99 79 101 79 95 85 76 94 82 87 85 99
a f Z _ r 9
102 108 97 103 123
flag{

ASCII码的差值递增：5、6、7.....。

9、拼音九键加密

利用字母在九键上的位置进行加密，特点：数字为偶数个，且偶数位的数小于5(九键上一个键上的字母最多是四个)

例：335321414374744361715332

两个数为一组分开：33 53 21 41 43 74 74 43 61 71 53 32

对应九键进行查找：3键的第三个字母、5键的第3个字母、……

10、当铺密码

以汉字为基础的一种密码，若汉字中任一笔画末端无其余笔画连接，则加入计数。(也就数俗话说的出头且不被连接的地方)

如：王=6、夫=7.

11、转盘密码(密码表+明文+密钥)

给出一个CTF的题(取自bugku)(字母矩阵注意结果可能在一行中，可能在一列中，也可能有其余情况，需要仔细观察，一般拼接后是单词)

1： <ZWAXJGDLUBVIQHKYPNTCRMOSFE <
2： <KPBELNACZDTRXMJQOYHGVSFUWI <
3： <BDMAIZVRNSJUWFHTEQGYXPLOCK <
4： <RPLNDVHGFCUKTEBSXQYIZMJWAO <
5： <IHFRLABEUOTSGJVDKCPMNZQWXY <
6： <AMKGHIWPNYCJBFZDRUSLOQXVET <
7： <GWTHSPYBXIZULVKMRAFDCEONJQ <
8： <NOZUTWDCVRJLXKISEFAPMYGHBQ <
9： <QWATDSRFHENYVUBMCOIKZGJXPL <
10： <WABMCXPLTDSRJQZGOIKFHENYVU <
11： <XPLTDAOIKFZGHENYSRUBMCQWVJ <
12： <TDSWAYXPLVUBOIKZGJRFHENMCQ <
13： <BMCSRFHLTDENQWAOXPYVUIKZGJ <
14： <XPHKZGJTDSENYVUBMLAOIRFCQW <

密钥： 2,5,1,3,6,4,9,7,8,14,10,13,11,12

密文：HCBTSXWCRQGLES

这是一个转盘加密：

比如第一个密钥匙：2、密文匙：H

把转盘第二行单独提出来 2： <KPBELNACZDTRXMJQOYHGVSFUWI <

从H的地方一直剪切，把剪切的内容放在最前面，变成 2： <HGVSFUWIKPBELNACZDTRXMJQOY <

依次类推把14行都按这样的方式整一遍就得到这个：

2：  <HGVSFUWIKPBELNACZDTRXMJQOY <
5：  <CPMNZQWXYIHFRLABEUOTSGJVDK <
1：  <BVIQHKYPNTCRMOSFEZWAXJGDLU <
3：  <TEQGYXPLOCKBDMAIZVRNSJUWFH <
6：  <SLOQXVETAMKGHIWPNYCJBFZDRU <
4：  <XQYIZMJWAORPLNDVHGFCUKTEBS <
9：  <WATDSRFHENYVUBMCOIKZGJXPLQ <
7：  <CEONJQGWTHSPYBXIZULVKMRAFD <
8：  <RJLXKISEFAPMYGHBQNOZUTWDCV <
14：<QWXPHKZGJTDSENYVUBMLAOIRFC <
10：<GOIKFHENYVUWABMCXPLTDSRJQZ <
13：<LTDENQWAOXPYVUIKZGJBMCSRFH <
11：<ENYSRUBMCQWVJXPLTDAOIKFZGH <
12：<SWAYXPLVUBOIKZGJRFHENMCQTD <

这个结果在第倒数第六行

12、26键密码

利用电脑键盘进行加密，有许多的类型，下面是本人遇到的

1）给出几组字母，每组字母在键盘上按顺序输入后轨迹会组成一个字母，把每组字母轨迹组成的字母提取出来组成密文。

2）利用键盘上字母的顺序：qwertyuiopasdfghjklzxcvbnm和26个字母顺序abcdefg……进行的运算加密，或者是将两个字母表进行顺序对应然后替换，见下表

13、JScript和VBScript脚本加密

具体的密文具体格式目前还不太清楚，应该和下面这个类似，见过一个VBScript脚本加密：

#@~^TgAAAA=='[6*liLa6++p'aXvfiLaa6i[[avWi[[a*p[[6*!I'[6cp'aXvXILa6fp[:6+Wp[:XvWi[[6+XivRIAAA==^#~@

14、DES加密(密钥+明文)(对称加密)

简单介绍一下：

摘自百度百科：

DES全称为Data Encryption Standard，即数据加密标准，是一种使用密钥加密的块算法，1977年被美国联邦政府的国家标准局确定为联邦资料处理标准（FIPS），并授权在非密级政府通信中使用，随后该算法在国际上广泛流传开来。需要注意的是，在某些文献中，作为算法的DES称为数据加密算法（Data Encryption Algorithm,DEA），已与作为标准的DES区分开来。

美国政府用过的加密标准，这个加密的原理很复杂，可以参考：https://blog.csdn.net/qq_27570955/article/details/52442092

解密网站：http://tool.oschina.net/encrypt

需要知道的是：1）key：8个字节共64位的工作密钥(有一位是就校验位，出去就是七位)

2）data：8个字节共64位的需要被加密或被解密的数据(加密后的密文很多采用base64和hex编码)

知道这key和data就能在网站上直接进行加解密了。

15、Ook加密

密文形式一（常见）：

Ook. Ook. Ook. Ook. Ook. Ook. Ook. Ook. Ook. Ook. Ook. Ook. Ook. Ook. Ook.
Ook. Ook. Ook. Ook. Ook. Ook! Ook? Ook! Ook! Ook. Ook? Ook. Ook. Ook. Ook.
Ook. Ook. Ook. Ook. Ook. Ook. Ook. Ook. Ook. Ook. Ook. Ook. Ook. Ook. Ook.
Ook. Ook? Ook. Ook? Ook! Ook. Ook? Ook. Ook. Ook. Ook. Ook. Ook. Ook. Ook.

密文形式二（不常见）：

..... ..... ..... ..... !?!!. ?.... ..... ..... ..... .?.?! .?... .!...
..... ..... !.?.. ..... !?!!. ?!!!! !!?.? !.?!! !!!.. ..... ..... .!.?.

16、Brainfuck加密

密文形式：

+++++ +++++ [->++ +++++ +++<] >++++ .---. +++++ ++..+ ++.<

解密：https://www.splitbrain.org/services/ook

17、base家族

base64：Base64编码是使用64个可打印ASCII字符（A-Z、a-z、0-9、+、/）将任意字节序列数据编码成ASCII字符串，另有“=”符号用作后缀用途。

例：bWV0YXNwb2xpdCBpcyBhIG91dHN0YW5kaW5nIHRvb2w=

base32：Base32编码是使用32个可打印字符（字母A-Z和数字2-7）对任意字节数据进行编码的方案，编码后的字符串不用区分大小写并排除了容易混淆的字符，可以方便地由人类使用并由计算机处理，另有“=”符号用作后缀用途。

例：NVSXIYLTOBXWY2LUEBUXGIDBEBXXK5DTORQW4ZDJNZTSA5DPN5WA====

base16：Base16编码使用16个ASCII可打印字符（数字0-9和字母A-F）对任意字节数据进行编码，没有“=”后缀。

例：6D65746173706F6C69742069732061206F75747374616E64696E6720746F6F6C

有时可能会把base64和base32的后缀“=”去掉，判断时要留意。

base家族不止这三个编码方式，还有base91等，但base64是目前最常用的了。

18、escape编码

escape是对字符串(string)进行编码，作用是让它们在所有电脑上可读，其中 ASCII字母、数字、@*/+ ，这几个字符不会被编码。
编码之后的效果是%XX或者%uXXXX这种形式，可能是\也不会被编码吧，也遇到过这种：\134\170\65\143。

19、十六进制编码

就是直接把明文加密成十六进制：0x5c这样的

20、ASCII码编码

直接用十进制形式的ASCII码来进行加密，直接转换即可

21、HTML加密

形式：

flag%7Bctf_tfc201717qwe%7D

22、MD5加密

MD5的典型应用是对一段信息（Message）产生信息摘要（Message-Digest），以防止被篡改。

密文以0-9和a-f组成：0ca175b9c0f726a831d895e269332461

MD5是不可逆的加密方式，也就是说不可能被解密，但可以使用撞库的方法来解，就是在存放密文-明文的库中寻找和已知密文对应的密文-明文对，从而找出明文。

23、银河字母加密

标准银河字母表：

24、ROT13

原理：（摘自百度百科）

套用ROT13到一段文字上仅仅只需要检查字元字母顺序并取代它在13位之后的对应字母，有需要超过时则重新绕回26英文字母开头即可。A换成N、B换成O、依此类推到M换成Z，然后序列反转：N换成A、O换成B、最后Z换成M。只有这些出现在英文字母里头的字元受影响；数字、符号、空白字元以及所有其他字元都不变。因为只有在英文字母表里头只有26个，并且26=2×13，ROT13函数是它自己的逆反： [1]

对任何字元x：ROT13(ROT13(x))=ROT26(x)=x。

换句话说，两个连续的ROT13应用函式会回复原始文字（在数学上，这有时称之为对合（involution）；在密码学上，这叫做对等加密（reciprocalcipher））。

转换可以利用查找表完成，如下例所示：

ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz

NOPQRSTUVWXYZABCDEFGHIJKLMnopqrstuvwxyzabcdefghijklm

例如，下面的英文笑话，精华句为ROT13所隐匿：

How can you tell an extrovert from an

introvert at NSA?Va gur ryringbef,

gur rkgebireg ybbxf ng gur BGURE thl'f fubrf.

透过ROT13表格转换整片文字，该笑话的解答揭露如下：

Ubj pna lbh gryy na rkgebireg sebz na

vagebireg ng AFN?In the elevators,

the extrovert looks at the OTHER guy's shoes.

第二次ROT13函数将转回原始文字。

25、utf7编码

这个编码好像已经不用了：

格式如下：前面是+号，后面是-号

+AGsAZQB5ADoAaQBhAG0AdQB0AGYANwBIAG4AYwBGQAZQBk-

26、aaencode

aaencode：将JS代码转换成常用的网络表情。直接在控制台就能解密。

27、jjencode

jjencode:将JS代码转换成只有符号的字符串。jjencode可以用自定义的符号对代码进行混淆，并且实际上的效果和加密的效果是一样的，因为如果不知道自定义的符号 key，过程是不可逆的。

$=~[];$={___:++$,$$$$:(![]+"")[$],__$:++$,$_$_:(![]+"")[$],_$_:++$,$_$$:({}+"")[$],$$_$:($[$]+"")[$],_$$:++$,$$$_:(!""+"")[$],$__:++$,$_$:++$,$$__:({}+"")[$],$$_:++$,$$$:++$,$___:++$,$__$:++$};$.$_=($.$_=$+"")[$.$_$]+($._$=$.$_[$.__$])+($.$$=($.$+"")[$.__$])+((!$)+"")[$._$$]+($.__=$.$_[$.$$_])+($.$=(!""+"")[$.__$])+($._=(!""+"")[$._$_])+$.$_[$.$_$]+$.__+$._$+$.$;$.$$=$.$+(!""+"")[$._$$]+$.__+$._+$.$+$.$$;$.$=($.___)[$.$_][$.$_];$.$($.$($.$$+"\""+$.$_$_+(![]+"")[$._$_]+$.$$$_+"\\"+$.__$+$.$$_+$._$_+$.__+"(\\\"\\"+$.__$+$.__$+$.___+$.$$$_+(![]+"")[$._$_]+(![]+"")[$._$_]+$._$+",\\"+$.$__+$.___+"\\"+$.__$+$.$$_+$.$$$+"\\"+$.__$+$.$$_+$.$$$+"\\"+$.__$+$.$$_+$.$$$+"."+$._$+"\\"+$.__$+$.$_$+$.__$+$.$$__+"\\"+$.__$+$.$$_+$.__$+"\\"+$.__$+$.$$$+$._$_+$._$+"\\"+$.__$+$.$_$+$.$$_+$.$$$_+"."+$.$$__+$._$+"\\"+$.__$+$.$_$+$.$_$+"\\\"\\"+$.$__+$.___+")"+"\"")())();

28、xor加密

解密很简单，直接进行异或就行了，给个例子：https://blog.csdn.net/zz_Caleb/article/details/88587238

29、64进制加密

64进制用的是base64的索引表进行的加密：

30、AES加密(密文+密钥，密钥可为空)

摘自百度百科：

高级加密标准（英语：Advanced Encryption Standard，缩写：AES），在密码学中又称Rijndael加密法，是美国联邦政府采用的一种区块加密标准。这个标准用来替代原先的DES。

32、幂数加密

摘自：https://baike.baidu.com/item/%E4%BA%8C%E8%BF%9B%E5%88%B6%E5%B9%82%E6%95%B0%E5%8A%A0%E5%AF%86%E6%B3%95/2410151?fr=aladdin

二进制数除了0和1的表示方法外，在由二进制转换成十进制的时候，还可以表示成2的N次方的形式。例如：

15=2^0+2^1+2^2+2^3

并且我们发现，任意的十进制数都可以用2^n或2^n+2^m+……的形式表示出来，可以表示的单元数由使用的max n来决定。

可表示的单元数=2^(n+1)-1

二进制幂数加密法就是应用这个原理，由于英文字母只有26个字母，由公式可知，只要2的0、1、2、3、4次幂就可以表示31个单元。通过用二进制幂数表示字母序号数来加密。例如

明文： d o n o t p u l l a l l y o u r e g g s i n o n e b a s k e t

字母序号：4 15 14 15 20 16 21 12 12 1 12 12 25 15 21 18 5 7 7 19 9 14 15 14 5 2 1 19 11 5 20

由于4=2^2 所以D加密过之后是2；15=2^0+2^1+2^2+2^3所以O加密后是0123。同理得到上述明文的加密后的密文

密文：2 0123/123 0123 24/4 024 23 23/0 23 23/034 0123 024 14/02 012 012 014/03 123 /0123 123 02/1 0 014 013 02 24

其中空格表示字母的间隔，/表示单词的间隔。

字母加密结果对照

A 1-------0

B 2-------1

C 3------01

D 4------2

E 5------02

F 6------12

G 7------012

H 8------3

I 9------03

J 10-----13

K 11-----013

L 12-----23

M 13----023

N 14----123

O 15----0123

P 16----4

Q 17----04

R 18----14

S 19-----014

T 20-----24

U 21-----024

V 22-----124

W 23-----0124

X 24-----34

Y 25-----034

Z 26-----134

我们拿到密文后，分组一定要分对，如：8842101220480224404014224202480122

0肯定是开头的，这样我们可以分成8组：
a=["88421","0122","048","02244","04","0142242","0248","0122"]

解密脚本：

a=["88421","0122","048","02244","04","0142242","0248","0122"]
flag=""
for j in range(0,len(a)): str = a[j] list=[] sum=0 for i in str: list.append(i) length = len(list) for i in range(0,length): sum+=int(list[i]) flag+=chr(64+sum)
print(flag)

解码为：
在所有邮件处理的各式各样的编码中，很多编码的目的都是通过编码手段使得七位字符的邮件协议体系可以传送八位的二进制文件、双字节语言文字等等。 Quoted-Printable也是这样一些编码中的一个，它的目的同样是帮助非ASCII 编码的信件传输通过 SMTP。Quoted-Printable 编码是字符对应的编码，每个未编码的二进制字符被编码成三个字符，即一个等号和一个十六进制的数字，如“A8”。

35、Rabbit加密

rabbit是公钥加密的一种，也就相当于是加盐的加密，其形式和base64及其相思

例：U2FsdGVkX19pDorZ2hTP+5w0zSA9bXhVezJy2umFTSp6PdN6zPKCMA==

base64解密是乱码的，rabbit解密得到：fxbqrwrvnwmngrjxsrnsrnhx
