spammimic加密

最近做Crypto题遇到了一种新的加密方式，用到了一个网站： https://www.spammimic.com/

主要用于把文本加密成垃圾邮件，查了一下，这个网站估计是用特定的内容来逐个字符进行替换

有网友试了一下每个字符的替换结果

a Dear Professional , Thank-you…
b Dear Professional , Especially…
c Dear Professional , This…
d Dear Professional ; You…
e Dear Professional ; Thank-you…
f Dear Professional ; Especially…
g Dear Professional ; This…
h Dear Decision maker , You…
i Dear Decision maker , Thank-you…
j Dear Decision maker , Especially…
k Dear Decision maker , This…
l Dear Decision maker ; You…
m Dear Decision maker ; Thank-you…
n Dear Decision maker ; Especially…
o Dear Decision Maker ; This…
p Dear Business person , You…
q Dear Business person , Thank-you
r Dear Business person , Especially
s Dear Business person , This…
t Dear Business person ; You…
u Dear Business person ; Thank-you…
v Dear Business person ; Especially…
w Dear Business person ; This…
x Dear E-Commerce professional , You…
y Dear E-Commerce professional , Thank-you…
z Dear E-Commerce professional , Especially…

网站有多种加密形式，这里开一篇文章记录一下。

1、垃圾邮件

Dear Decision maker ; Especially for you - this cutting-edge 
intelligence . This is a one time mailing there is 
no need to request removal if you won't want any more 
. This mail is being sent in compliance with Senate 
bill 1621 , Title 5 ; Section 302 . This is NOT unsolicited 
bulk mail ! Why work for somebody else when you can 
become rich in 85 months ! Have you ever noticed how 
long the line-ups are at bank machines and more people 
than ever are surfing the web . Well, now is your chance 
to capitalize on this . WE will help YOU deliver goods 
right to the customer's doorstep & process your orders 
within seconds ! You can begin at absolutely no cost 
to you ! But don't believe us . Mrs Anderson of Illinois 
tried us and says "I've been poor and I've been rich 
- rich is better" ! This offer is 100% legal ! Don't 
delay - order today . Sign up a friend and you get

垃圾邮件有有密码的加密和无密码的加密两种形式。

2、账单

估计是和垃圾邮件同理的按字符替换

Expenses
Gas,$3370.27
Security Alarm,$5.09
Heating,$1.58
Motor Vehicle,$55.40
Entertainment,$6.00
Software Licenses,$20.64
Advertising,$5.89

3、俄语

用形状相似的俄文字母进行替换

flag{asdfaldjflajofuas987d9f7a987ds9f7as98d7f9}
ғӀаӵ{аѕәғаӀәјғӀајоғџаѕ987ә9ғ7а987әѕ9ғ7аѕ98ә7ғ9}

4、空格

在后面跟很多空格，实则是加密的密文
