echo BAT加密最終版為"BAT加密工具"的更新版本, 較上一版加密工具而言有諸多優勢:

echo   可以一次性成功加密任何批處理檔案, 更省事.

echo   可以由您輸入任意需要加密的批處理, 加密靈活性更大.

echo   能夠自動判斷錯誤輸入, 更加人性化.

echo 說明: 在下面輸入需要加密的批處理檔案, 直接輸入批處理檔案名為加密目前目錄下的BAT,也可以帶路徑指定任意BAT. 目前目錄下生成的encrypt.bat檔案即為加密的批處理. 

set /p file=請輸入需要加密的批處理後按Enter鍵(q=退出):

if "%file%"=="q" goto quit

echo %file%|findstr /i "\.bat$">nul && goto go

echo %file%|findstr /i "\.cmd$">nul && goto go

echo ==============

echo 請正确輸入!

echo 按任意鍵重新輸入......
