echo BAT加密最终版为"BAT加密工具"的更新版本, 较上一版加密工具而言有诸多优势:

echo   可以一次性成功加密任何批处理文件, 更省事.

echo   可以由您输入任意需要加密的批处理, 加密灵活性更大.

echo   能够自动判断错误输入, 更加人性化.

echo 说明: 在下面输入需要加密的批处理文件, 直接输入批处理文件名为加密当前目录下的BAT,也可以带路径指定任意BAT. 当前目录下生成的encrypt.bat文件即为加密的批处理. 

set /p file=请输入需要加密的批处理后按回车键(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 请正确输入!
