You have to make a loop with an IF test to check if the char is lower or upper case :

Example :

@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:#= !
