Batch file 批处理文件以允许对此代码的大写字母进行加密和解密

我希望这个代码能够加密大写字母，因为当我添加大写字母时，它会像小写字母一样加密

这是密码 加密码

解密码

必须使用

IF

测试进行循环，以检查字符是小写还是大写：

示例：

@echo off

::The string to Encrypt

set "$string=aBA baB"

setlocal enabledelayedexpansion

for /l %%i in (0,1,9000) do (
   set char=!$string:~%%i,1!
      if "!char!"==" " set char=#
      if defined char (

REM here the tests and substitutions
         if !char!==a set "char=!char:a=[aSmall]!"
         if !char!==A set "char=!char:A=[ACapital]!"
         if !char!==b set "char=!char:b=[bSmall]!"
         if !char!==B set "char=!char:B=[BCapital]!"

         set "$final=!$final!!char!"
        )
)
echo %$String% --^> !$final:#= !

那么，如果代码太长，你也应该要求缩小它<代码>：-）这是加密部分的解决方案：

@echo off
setlocal  EnableDelayedExpansion

rem Create the encryption array
for %%a in ("UA=45UDFM" "UB=GFH21D" "UC=6DFDH5" "UD=46FGS5" "UE=JHJUK4" "UF=4SERG5"

set lowCase=abcdefghijklmnopqrstuvwxyz

   set char=%Encrypt2:~0,1%

解密部分与原始部分完全相同，只需添加一组大写字母…

请在问题本身中包含代码。你试过做那件事吗？你遇到什么问题了吗？你发现任何东西的方法似乎把问题抛到了StackOverflow上——这不是适当的研究，也不会引出非常有趣的问题——最后一部分就是问题所在。artjom我写了我的问题（能够加密大写字母，因为当我添加大写字母时，它将像小写字母一样加密）我可以把完整的代码，因为它是longi发现，我没有发现代码有加密和解密，能够加密和解密大写字母、小写字母和数字问题是我不能把你和SachaDee接受的答案放在一起我试着它不起作用
