跳过设置提示(设置/p)批处理中的最大长度? [英] Bypass maximum length in set prompt (set /p) batch?
问题描述
我有一个批处理脚本，用于混淆字符串，然后将其转换回可读的文本(将字母转换为数字，并在其间放置一堆随机的ascii特殊字符).问题是当复制很长的字符串时，反混淆器会在中间切断.我用
I have a batch script that obfuscates a string, and one that turns it back into readable text (it turns the letters into numbers and puts a bunch of random ascii special characters between). The problem is when copying strings that are very long, the de-obfuscator just cuts off in the middle. I use
set /p "text=Text:"
并将变量复制粘贴到该字段中.我输入混淆器的代码是
and copy paste the variable into the field. The code i enter in to the obfuscator is
START EXIT & ECHO OFF & SET filename=CachedImage_1920_1080_POS4.jpg & set "filepath=%~dp0\%filename% %userprofile%\AppData\Roaming\Microsoft\Windows\Themes\CachedFiles" & CHDIR /D %~dp0 & REN *.jpg %filename% & REN *.png %filename% & REN *.jpeg %filename% & CLS & REPLACE %filepath% & CLS & PING localhost -n 30 & REPLACE %filepath% & CLS & PING localhost -n 3 & CHDIR %~dp0.. & RMDIR %~dp0 /S /Q

但是当我再次进行模糊处理时，大约丢失了原始文本的四分之一.混淆代码的长度为1540个字符，这很奇怪，因为字符串的最大长度显然是8000左右.帮助将非常宝贵.
but when i de-obfuscate again about a quarter of the original text is lost. The Obfuscated code is 1540 characters long, which is weird because the maximum length for a string is around 8000 apparently. Help would be very much apreciated.
(顺便说一句，我试图混淆的脚本是用于更改桌面背景的)
(By the way, the script i am trying to obfuscate is for changing the desktop background)
这是混淆器&的代码.除臭剂
Here is the code for the Obfuscator & De-Obfuscator
混淆器:
@echo off
setlocal enableDelayedExpansion
set /p code=Text:
set chars=01234567890abcdefghijklmnopqrstuvwxyz()/%%
Set _Alphanumeric=æÆôòûù¢£¥ƒáíóúñÑ¿¬½¼¦ßµ±°•²€…†‡‰Š‹Œ—™š›œŸ«»˜–¶§@
Set _count=0
:redo
If !_count! leq 204 call :loop
for /L %%N in (10 1 40) do (
for /F %%C in ("!chars:~%%N,1!") do (
set vals=!str:~%%N,1!%%N!str:~-%%N,1!
for /F %%F in ("!vals!") do (
set "code=!code:%%C=%%F!"
)
)
)
echo !code!
pause
exit
:loop
Set /a _count+=1
set _RND=%random%
Set /A _RND=_RND%%48
SET str=!str!!_Alphanumeric:~%_RND%,1!
goto redo
去混淆剂:
@echo off
setlocal enableDelayedExpansion
set /p code=Text:
set chars=01234567890abcdefghijklmnopqrstuvwxyz()/%%
for /L %%N in (10 1 40) do (
for /F %%C in ("!chars:~%%N,1!") do (
set "code=!code:%%N=%%C!"
)
)
for /F %%F in ("!code!") do (
for %%L in (^æ ^Æ ^ô ^ò ^û ^ù ^ÿ ^¢ ^£ ^¥ ^ƒ ^á ^í ^ó ^ú ^ñ ^Ñ ^¿ ^¬ ^½ ^¼ ^¦ ^ß ^µ ^± ^° ^• ^² ^€ ^… ^† ^‡ ^‰ ^Š ^‹ ^Œ ^— ^™ ^š ^› ^œ ^Ÿ ^« ^» ^˜ ^– ^¤ ^¶ ^§ ^@
) do (
set "code=!code:%%L=!"
)
)
echo !code!
pause
推荐答案
set/p 的限制为〜1023个字符.
set /p has a limit of ~1023 characters.
没有简单的方法可以解决此问题，但是您可以将输入分成多行.
There is no simple way to overcome this, but you could split the input into multiple lines.
或者您使用类似的方法，但是您需要使用CTRL-Z停止输入
Or you use something like this, but then you need to stop the input with CTRL-Z
findstr "^" > input.txt
