What is most concerned is: Excuse me, moderators and experts such as yuanyong630, if this tool is used to encrypt a more complex batch processing, will there be operation errors and other situations?

It should not. After encryption, only a section of code is generated at the beginning of the file. When this section of code is run, an error will be prompted.

Then the following commands will be executed. It will not interrupt the execution of the following commands. Please rest assured.

This method can be seen with type under DOS. I think the best one is still the encryption method proposed by the moderator of version 3742668 on the 11th floor. After all, no one will slowly look for your code among so many English words???

If this tool is used to encrypt more complex batch processing, there will be no any problems.

Thanks "pengfei".

Finally, I bring a section of code. Everyone guess what the password is? (It's very simple)

@echo off
set a=1
set d=0
:sub
cls
@echo.
@echo.
@echo.
@echo.
@echo.
@echo.
@echo.
choice /c:1234567890 /n . Please enter the DOS entry password (3-%a%):

if errorlevel 10 goto 10
if errorlevel 9 goto 9
if errorlevel 8 goto 8
if errorlevel 7 goto 7
if errorlevel 6 goto 6
if errorlevel 5 goto 5
if errorlevel 4 goto 4
if errorlevel 3 goto 3
if errorlevel 2 goto 2

if %a%==3 goto run
if %a%==2 set a=3
if %a%==1 set a=2
goto sub

:10
if %d%==2 set d=3
if %a%==3 goto run
if %a%==2 set a=3
if %a%==1 set a=2
goto sub

:9
if %a%==3 goto run
if %a%==2 set a=3
if %a%==1 set a=2
goto sub

:8
if %a%==3 goto run
if %a%==2 set a=3
if %a%==1 set a=2
goto sub

:7
if %d%==0 set d=1
if %a%==3 goto run
if %a%==2 set a=3
if %a%==1 set a=2
goto sub

:6
if %a%==3 goto run
if %a%==2 set a=3
if %a%==1 set a=2
goto sub

:5
if %d%==1 set d=2
if %a%==3 goto run
if %a%==2 set a=3
if %a%==1 set a=2
goto sub

:4
if %a%==3 goto run
if %a%==2 set a=3
if %a%==1 set a=2
goto sub

:3
if %a%==3 goto run
if %a%==2 set a=3
if %a%==1 set a=2
goto sub

:2
if %a%==3 goto run
if %a%==2 set a=3
if %a%==1 set a=2
goto sub

:run
if %d%==3 goto end
cls
@echo Incorrect password, please enter again!!!
pause >nul
goto sub

:end

Simpler way:
Create a new "a.txt" text file, open it, copy 【ൡ挊獬਍】(excluding the 【】), paste it into "a.txt" text file. When saving, it prompts "Contains Unicode characters....", select "Cancel", change the encoding to "Unicode" and save.

Batch processing: copy/b a.txt+the file to be encrypted.bat encrypted.bat

Re zxcv『Post 14』:

According to your plan, an automated password generator script with relatively high automation has been made. Since it uses itself as the encryption key, it is itself a segment of ciphertext, so the code cannot be posted directly, and can only be uploaded as an attachment.

Re yuanyong630
Brother, the code on floor 34, I cracked it by inputting from 9 to 0. In the worst case, you can crack it by inputting from 0 to 9 three times in a row. It seems you forgot to clear the variable d at the appropriate time.

Although I haven't interjected all the time, this discussion is very interesting. I also occasionally try to encrypt something.

My code does have some bugs. Thanks everyone! I've learned a lot! Thanks

Re zxcv『Post 14』:

Made an automated password generator script with a relatively high level of automation according to your plan. Since it uses itself as the encryption key, it is itself a piece of ciphertext, so therefore...

Modify it: if not == if exist %1 copy /b "%~f0"+%1 enc_%1>nul&echo. Enc_%1 is create.&goto :eof

Remove the ":EncryBat_Encryption" part

Just keep the following for actual use:

@echo off
if......
if......
:EncryBat_Display

就行了^_^

Re zxcv:

There is a small issue with your modification. In the line "if not == if exist %~f1", the enhanced command line parameter reference (%~1) is used, so it needs to be enclosed in quotes to prevent a syntax error when the file name contains spaces. As follows:

if not "%~n1"=="" if exist "%~f1" ...

If the original parameter reference (%1) is used, because the system or the caller automatically adds quotes to parameters containing spaces, quotes should not be used at this time, otherwise the spaces in the parameters will be exposed due to incorrect quote matching. For example:

if not ""space file name""=="" if exist ""space file name"" ... (syntax error)

If the enhanced parameter reference (%~1) is used, because the quotes in parameters containing spaces are automatically removed by the system, quotes must be used at this time, otherwise the spaces in the parameters will be exposed due to the lack of quote protection.

if not == if exist space file name ... (syntax error)

Thanks to moderator willsort for the correction.

The modifications are as follows:

1. @echo off
   
2. if not "%~n0"=="EncryBat" goto EncryBat_Display
   
3. if not "%~n1"=="" if exist "%~f1" copy/b "%~f0"+"%~f1" "%~dp1enc_%~nx1">nul 2>nul&cls&echo.&echo. Enc_%~nx1 is create.&goto :eof
   
4. 
   
5. :EncryBat_Help
   
6. echo.
   
7. echo %~n0 - Cryptographic machine for batch program
   
8. echo zxcv@cn-dos, willsort@cn-dos - 2006-8-4 - CMD@WinXP
   
9. echo.
   
10. echo Useage: %~n0 batch_program_with_extname
    
11. echo Reference: http://www.cn-dos.net/forum/viewthread.php?tid=22053
    
12. if /i not %0]== pause
    
13. goto :eof
    
14.

Correct the error that encrypted files cannot be generated for file names with spaces

The text in the graphical menu window of the encrypted batch processing opened in the CMD window is incorrect when using the EncryBat from the upper floor!
